C 语言部门管理系统

2024年08月28日 | 阅读 29 分钟

这个部门商店管理系统完全基于提供有关添加、计算、检查产品以及其他功能的信息的理念。管理员或客户能够完全了解数据，没有任何压力。该程序在处理付款时犯错的潜在可能性很小，并且还能减少向客户提交付款的延迟。由于记录丢失的风险最低，我们不必担心此系统会崩溃。

它的优点之一是能够立即将远程用户连接到远程资源。可扩展的系统可以是开放系统（其中每个组件始终可与其他组件交互）或封闭系统（系统可以快速修改以处理用户数量的变化等）。在零售行业，一个强大的部门商店管理系统是您最重要的资产之一。如果一切按计划进行，这将如同拥有自己的专家团队在幕后确保顺畅运行。要在当今竞争激烈的零售世界中成功经营您的企业，您需要一个 DSM 系统。

您只需提供产品的证据信息。添加产品后，您将被发送到计算账单选项。您可以在此菜单中找到您的全部应付金额。如果您愿意，产品是可编辑的。必须先提供产品代码。同样，您可以选择删除其他商品。显示选项将列出您购买的所有商品。如果您记不清商品，请搜索。

通过这种方法，您可以随时退出。系统就是这样运行的。项目代码非常容易理解。您的记录由项目保存为文本文件。我强烈建议在使用此项目的源代码时使用 Dev C++ 代码编辑器。它具有编译和运行的能力，并且可以轻松识别错误。下载项目以获得第一手体验。

程序分解

void gotocoordinate ( int x , int y )
{
    coordinates.X = x ;
    coordinates.Y = y ;
    SetConsoleCursorPosition ( GetStdHandle ( STD_OUTPUT_HANDLE ) , coordinates ) ;
}

上述代码用于设置控制台光标位置。

typedef struct
{
    char name [ CNN ] , code [ CBN ] ;
    float rate ;
    int quantity ;
} record ;
record stocks ;

为记录创建结构。

void cur ( int ) ;
void departmentbill ( ) ;
void department_menu ( ) ;
void view ( record * , int , int ) ;
void window_screen ( int , int , int , int ) ;
void view_concern ( ) ;
void department_search ( ) ;
void h_light ( int , int ) ;

void cal_bill ( ) ;
void modify ( ) ;
void add_stocks ( ) ;
void delete_stocks ( ) ;
void exit ( ) ;

void depart_code ( ) ;
void depart_rate ( ) ;
void depart_qty ( ) ;
void depart_all ( ) ;

以上将是我们代码中的函数。

void department_menu ( )
{
    int a ;
    char st ;
    const char * menu [ ] = { "   Calculate Bill " , " Add Goods " , " Edit Goods " , " Display All " , " Search " , " Delete Goods " , " Exit " } ;
    system ( " cls " ) ;
    window_screen ( 25 , 50 , 20 , 32 ) ;
    gotocoordinate ( 33 , 18 ) ;
    printf ( " MAIN MENU " ) ;
    for ( a = 0 ; a < = 6 ; a + + )
    {
        gotocoordinate ( 30 , 22 + a + 1 ) ;
        printf ( " % s \ n \ n \ n " , menu [ a ] ) ;
    }
    cur ( 7 ) ;
}

以上代码将显示部门菜单。

void department_search ( )
{
    char st ;
    int a ;
    const char * menu [ ] = { " By Code " , " By Rate " , " By Quantity " , " Back to main menu " } ;
    system ( " cls " ) ;

    window_screen ( 25 , 50 , 20, 32 ) ;
    gotocoordinate ( 33 , 18 ) ;
    printf ( " SEARCH MENU " ) ;
    for ( a = 0 ; a < = 3 ; a + + )
    {
        gotocoordinate ( 30 , 22 + a + 1 ) ;
        printf ( " % s \ n \ n \ n " , menu [ a ] ) ;
    }
    cur ( 4 ) ;
}

要在部门商店中搜索，将执行上述代码。

void cur ( int no )
{
    int counting = 1 ;
    char st = ' 0 ' ;
    gotocoordinate ( 30 , 23 ) ;
    while ( 1 )
    {
        switch ( st ) 
        {
        case 80 :
            counting + + ;
            if ( counting = = no + 1 ) counting = 1 ;
            break ;
        case 72 :
            counting - - ;
            if ( counting = = 0 ) counting = no ;
            break ;
        }
        h_light ( no , counting ) ;
        st = getch ( ) ;
        if ( st = = ' \ r ' )
        {
            if ( no = = 7 )
            {
                if ( counting = = 1 ) cal_bill ( ) ;
                else if ( counting = = 2 ) add_stocks ( ) ;
                else if ( counting = = 3 ) modify ( ) ;
                else if ( counting = = 4 ) depart_all ( ) ;
                else if ( counting = = 5 ) department_search ( ) ;
                else if ( counting = = 6 ) delete_stocks ( ) ;
                else exit ( 0 ) ;
            }
            if ( no = = 4 )
            {
                if ( counting = = 1 ) depart_code ( ) ;
                else if ( counting = = 2 ) depart_rate ( ) ;
                else if ( counting = = 3 ) depart_qty ( ) ;
                else department_menu ( ) ;
            }
        }
    }
}

根据用户，上述代码将帮助向部门商店添加商品。

void h_light ( int no , int count )
{
    if ( no = = 4 )
    {

        gotocoordinate ( 30 , 23 ) ;
        printf ( " By Code " ) ;
        gotocoordinate ( 30 , 24 ) ;
        printf ( " By Rate " ) ;
        gotocoordinate ( 30 , 25 ) ;
        printf ( " By Quantity " ) ;
        gotocoordinate ( 30 , 26 ) ;
        printf ( " Back to main menu " ) ;

        switch ( count )
        {
        case 1 :
            gotocoordinate ( 30 , 23 ) ;
            printf ( " - By Code " ) ;
            break ;
        case 2 :
            gotocoordinate ( 30 , 24 ) ;
            printf ( " - By Rate " ) ;
            break ;
        case 3 :
            gotocoordinate ( 30 , 25 ) ;
            printf ( " - By Quantity " ) ;
            break ;
        case 4 :
            gotocoordinate ( 30 , 26 ) ;
            printf ( " - Back to main menu " ) ;
            break ;
        }
    }

    if ( no = = 7 )
    {

        gotocoordinate ( 30 , 23 ) ;
        printf ( " Calculate Bill " ) ;
        gotocoordinate ( 30 , 24 ) ;
        printf ( " Add Goods " ) ;
        gotocoordinate ( 30 , 25 ) ;
        printf ( " Edit Goods " ) ;
        gotocoordinate ( 30 , 26 ) ;
        printf ( " Display All " ) ;
        gotocoordinate ( 30 , 27 ) ;
        printf ( " Search " ) ;
        gotocoordinate (30,28);
        printf ( " Delete Goods " ) ;
        gotocoordinate ( 30 , 29 ) ;
        printf ( " Exit " ) ;

        switch ( count )
        {
        case 1 :
            gotocoordinate ( 30 , 23 ) ;
            printf ( " - Calculate Bill " ) ;
            break ;
        case 2 :
            gotocoordinate ( 30 , 24 ) ;
            printf ( " - Add Goods " ) ;
            break ;
        case 3 :
            gotocoordinate ( 30 , 25 ) ;
            printf ( " - Edit Goods " ) ;
            break ;
        case 4 :
            gotocoordinate ( 30 , 26 ) ;
            printf ( " - Display All " ) ;
            break ;
        case 5 :
            gotocoordinate ( 30 , 27 ) ;
            printf ( " - Search " ) ;
            break ;
        case 6 :
            gotocoordinate ( 30 , 28 ) ;
            printf ( " - Delete Goods " ) ;
            break ;
        case 7 :
            gotocoordinate ( 30 , 29 ) ;
            printf ( " - Exit " ) ;
            break ;
        }
    }
}

以上代码将显示部门管理系统的菜单。

void cal_bill ( )
{
    char c [ 4 ] = { 0 } ; 
    int d = 29 , e = 0 , size = 0 , f = 1 ;
    float d_tot = 0 , gross_tot = 0 ;
    FILE * openfile ;
    openfile = fopen ( " record.txt " , " r + b " ) ;
    rewind ( openfile ) ;
    system ( " cls " ) ;
    departmentbill ( ) ;
    gotocoordinate ( 26 , 15 ) ;
    printf ( "enter  \ " end \ " to finish input " ) ;
    while ( 1 )
    {
        gotocoordinate ( 25 , 18 ) ;
        printf ( " " ) ;
        gotocoordinate ( 25 , 19 ) ;
        printf ( " " ) ;

        printf ( " enter item code : " ) ;
        scanf ( " % s " , c ) ;
        if ( strcmp ( c , " end " ) = = 0 )
            break ;
        gotocoordinate ( 25 , 19 ) ;
        printf ( " enter quantity : " ) ;
        scanf ( " % d " , & e ) ;
        rewind ( openfile ) ;
        while ( fread ( & stocks , sizeof ( stocks ) , 1 , openfile ) )
        {
            if ( ( strcmp ( stocks.code , c  ) = = 0 ) ) 
            {
                d_tot=stocks.rate * e ;
                gotocoordinate ( 11 , d ) ;
                printf ( " % 4 d " , f ) ;
                printf ( " % 9 s " , stocks.name ) ;
                printf ( " % 13 d " , e ) ;
                printf ( " % 15.2 f " , stocks.rate ) ;
                printf ( " % 13.2 f " , d_tot ) ;
                gross_tot = gross_tot + d_tot ;
                size = sizeof ( stocks ) ;
                stocks.quantity = stocks.quantity - e ;
                d + = 2 ;
                f + + ;
                fseek ( openfile , -size , SEEK_CUR ) ;
                fwrite ( & stocks , sizeof ( stocks ) , 1 , openfile ) ;
                break ;
            }
        }
    }
    if ( gross_tot ! = 0 )
    {
        gotocoordinate ( 30 , d + 5 ) ;
        printf ( " TOTAL AMOUNT = P % 6.2 f " , gross_tot ) ;
    }
    fclose ( openfile ) ;
    getch ( ) ;
    department_menu ( ) ;
}

以上代码将计算所选商品的账单。

void departmentbill ( )
{
    int a ;
    gotocoordinate ( 20 , 10 ) ;
    for ( a = 1 ; a < = 10 ; a + + )
        printf ( " * " ) ;
    printf ( " * FASHION WEAR * " ) ;
    for ( a = 1 ; a < = 10 ; a + + )
        printf ( " * " ) ;
    printf ( " \ n \ n " ) ;
    gotocoordinate ( 30 , 11 ) ;
    printf ( " Departmental Store " ) ;
//textcolor ( 1 ) ;
    gotocoordinate ( 32 , 25 ) ;
    printf ( " CUSTOMER'S BILL " ) ;
//textcolor ( 8 ) ;
    gotocoordinate ( 13 , 27 ) ;
    printf ( " SN.   Item Name     Quantity     Rate     Total " ) ;
}

以上代码将向用户显示所选商品和账单。

void add_stocks ( )
{
    FILE * openfile ;
    char l [ CBN ] , m [ 12 ] ;
    system ( " cls " ) ;
//textbackground ( 11 ) ;
//textcolor ( 0 ) ;
    gotocoordinate ( 25 , 25 ) ;
    printf ( " Enter new record ( Y / N ) ? " ) ;
    while ( toupper ( getche ( ) ) = = ' Y ' )
    {
        system ( " cls " ) ;
        openfile = fopen ( " record.txt " , " ab " ) ;
        checking_code ( l ) ;
        strcpy ( stocks.code , l ) ;
        gotocoordinate ( 22 , 28 ) ;
        printf ( " Enter rate of the item : " ) ;
        scanf ( " % f " , & stocks.rate ) ;
        gotocoordinate ( 22 , 30 ) ;
        printf ( " Enter quantity of the item : " ) ;
        scanf ( " % d " , & stocks.quantity ) ;
        gotocoordinate ( 22 , 32 ) ;
        printf ( " Enter name of the item : " ) ;
        scanf ( " % s " , stocks.name ) ;
        fseek ( openfile , 0 , SEEK_END ) ;
        fwrite ( & stocks , sizeof ( stocks ) , 1 , openfile ) ;
        fclose ( openfile ) ;
        gotocoordinate ( 22 , 34 ) ;
        printf ( " Enter new record ( Y / N ) ? " ) ;

    }
    department_menu ( ) ;
}

如果所有者想添加商品的库存，那么将执行上述代码。

void checking_code ( char y [ ] )
{
    int flagerized ;
    FILE * openfile ;
    openfile = fopen ( " record.txt " , " rb " ) ;
    while ( 1 )
    {
        system ( " cls " ) ;
        window_screen ( 20 , 58 , 23 , 36 ) ;
        gotocoordinate ( 32 , 18 ) ;
        printf ( " ADD ARTICLES " ) ;
        flagerized = 1 ;
        rewind ( openfile ) ;
        gotocoordinate ( 22 , 25 ) ;
        printf ( " Enter new code of the article : " ) ;
        scanf ( " % [ ^ \ n ] " , y ) ;
        while ( fread ( & stocks , sizeof ( stocks ) , 1 , openfile ) = = 1 )
        {
            if ( strcmp ( y , stocks.code ) = = 0 )
            {
                flagerized = 0 ;
                gotocoordinate ( 26 , 30 ) ;
                printf ( " code already exists " ) ;
                gotocoordinate ( 29 , 32 ) ;
                printf ( " enter again " ) ;
                getch ( ) ;
                break ;
            }
        }
        if ( flagerized = = 1 )
            break ;
    } 
}

以上代码将检查输入的商品代码。

void modify ( )
{
    int flagerized = 0 , options ;
    char r [ CBN ] , s [ CBN ] ;
    FILE * openfile ;
    int sze ;
    system ( " cls " ) ;

    printf ( " EDIT RECORDS " ) ;
    gotocoordinate ( 25 , 23 ) ;
    printf ( " enter item code : " ) ;
    scanf ( " % s " , r ) ;
    flagerized = checking ( r ) ;
    if ( flagerized = = 0 )
    {
        openfile = fopen ( " record.txt " , " r + b " ) ;
        rewind ( openfile ) ;
        while ( fread ( & stocks , sizeof ( stocks ) , 1 , openfile ) )
        {
            if ( strcmp ( stocks.code , r ) = = 0 )
            {

                printf ( " quantity = % d " , stocks.quantity ) ;
                gotocoordinate ( 25 , 32 ) ;
                printf ( " Do you want to edit this record ? ( y / n ) : " ) ;

                        sze = sizeof ( stocks ) ;
                        fseek ( openfile , - sze , SEEK_CUR ) ;
                        fwrite ( & stocks , sizeof ( stocks ) , 1 , openfile ) ;
                        break ;
                    case 4 :  
                        system ( " cls " ) ;
                        window_screen ( 23 , 65 , 20 , 40 ) ;
                        gotocoordinate ( 35 , 18 ) ;
                        printf ( " EDIT RECORDS " ) ;
                        gotocoordinate ( 25 , 24 ) ;
                        printf ( " enter new quantity : " ) ;
                        scanf ( " % d " , & stocks.quantity ) ;

        }
    }
    if ( flagerized = = 1 )
    {
        gotocoordinate ( 32 , 30 ) ;
        printf ( " Item does not exist. " ) ;
        gotocoordinate ( 36 , 32 ) ;
        printf ( " TRY ABGAIN " ) ;
    }
    getch ( ) ;
    fclose ( openfile ) ;
    department_menu ( ) ;

以上代码将帮助修改库存。

void depart_all ( )
{
    int a , d = 1 ;
    FILE * openfile ;
    view_concern ( ) ;
    openfile = fopen ( " record.txt " , " rb " ) ;
    rewind ( openfile ) ;
    a = 26 ;
    fflush ( openfile ) ;
    while ( fread ( & stocks , sizeof ( stocks ) , 1 , openfile ) )
    {
        view ( & stocks , a , d ) ;
        a + + ;
        d + + ;
        if ( ( d % 20 ) = = 0 )
        {
            gotocoordinate ( 27 , 47 ) ; / * textcolor ( 0 ) * / ;
            printf ( " Press any key to see more........... " ) ;
            getch ( ) ;
            system ( " cls " ) ;
            view_concern ( ) ;
            a = 26 ;
            continue ;
        }
    }
    getch ( ) ;
    if ( a = = 26 )
    {
        gotocoordinate ( 24 , 30 ) ;
        printf ( " -- no articles found -- " ) ;
    }
    getch ( ) ;
    fclose ( openfile ) ;
    department_menu ( ) ;
}

如果用户想更改所选选项，那么将执行上述代码。

void depart_qty ( )
{
    int s , t = 1 ;
    int p , q ;
    FILE * openfile ;
    view_concern ( ) ;
    openfile = fopen ( " record.txt " , " rb " ) ;
    rewind ( openfile ) ;
    s = 26 ;
    gotocoordinate ( 16 , 20 ) ;
    printf ( " Enter lower range : " ) ;
    scanf ( " % d " , & p ) ;
    gotocoordinate ( 16 , 21 ) ;
    printf ( " Enter upper range : " ) ;
    scanf ( " % d " , & q ) ;
    fflush ( openfile ) ;
    while ( fread ( & stocks , sizeof ( stocks ) , 1 , openfile ) )
    {
        if ( ( stocks.quantity > = p ) & & ( stocks.quantity < = q ) )
        {
            view ( & stocks , s , t ) ;
            s + + ; 
            t + + ;
            if ( ( t % 20 ) = = 0 )
            {
                gotocoordinate ( 27 , 47 ) ;
                printf ( " Press any key to see more........... " ) ;
                getch ( ) ;
                system ( " cls " ) ;
                view_concern ( ) ;
                s = 26 ;
                continue ;
            }
        }
    }
    getch ( ) ;
    if ( s = = 26 )
    {
        gotocoordinate ( 28 , 30 ) ;
        printf ( " No items found. " ) ;
    }
    getch ( ) ;
    department_search ( ) ;
    fclose ( openfile ) ;
}

将使用上述代码添加库存数量。

void depart_rate ( )
{
    int s , t = 1 ;
    float p , q ;
    FILE * openfile ;
    view_concern ( ) ;
    openfile = fopen ( " record.txt " , " rb " ) ;
    rewind ( openfile ) ;
    s = 26 ;
    gotocoordinate ( 16 , 20 ) ;
    printf ( " enter lower range : " ) ;
    scanf ( " % f " , & p ) ;
    gotocoordinate ( 16 , 21 ) ;
    printf ( " enter upper range : " ) ;
    scanf ( " % f " , & q ) ;
    fflush ( openfile ) ;
    while ( fread ( & stocks , sizeof ( stocks ) , 1 , openfile ) )
    {
        if ( ( stocks.rate > = p ) & & ( stocks.rate < = q ) )
        {
            view ( & stocks , s , t ) ;
            s + + ;
            t + + ;
            if ( ( t % 20 ) = = 0 )
            {
                gotocoordinate ( 27 , 47 ) ;
                printf ( " press any key to see more ........... " ) ;
                getch ( ) ;
                system ( " cls " ) ;
                view_concern ( ) ;
                s = 26 ;
                continue ;
            }
        }
    }
    getch ( ) ;
    if ( s = = 26 )
    {
        gotocoordinate ( 28 , 30 ) ;
        printf ( " no item found " ) ;
    }
    getch ( ) ;
    fclose ( openfile ) ;
    department_search ( ) ;
}

商品的价格将使用上述代码设置。

void depart_code ( )
{
    int s , t = 1 ;
    char d [ 4 ] = { 0 } ;
    FILE * openfile ;
    view_concern ( ) ;
    openfile = fopen ( " record.txt " , " rb " ) ;
    rewind ( openfile ) ;
    s = 26 ;
    gotocoordinate ( 16 , 20 ) ;
    printf ( " enter item code : " ) ;
    scanf ( " % s " , d ) ;
    fflush ( openfile ) ;
    while ( fread ( & stocks , sizeof ( stocks) , 1 , openfile ) )
    {
        if ( ( strcmp ( stocks.code , d ) = = 0 ) )
        {
            view ( & stocks , s , t ) ; 
            s + + ;
            t + + ;
            break ;
        } 
    }
    if ( s = = 26 )
    {
        gotocoordinate ( 28 , 30 ) ;
        printf ( " no item found " ) ;
    }
    getch ( ) ;
    fclose ( openfile ) ;
    department_search ( ) ;
}

如果用户输入了错误的商品代码，那么上述代码将标志一个错误。

void view_concern ( )
{
    int a ;
    system ( " cls " ) ;
    gotocoordinate ( 20 , 10 ) ;
    for ( a = 1 ; a < = 10 ; a + + )
        printf ( " * " ) ;
    printf ( " * FASHION WEAR * " ) ;
    for ( a = 1 ; a < = 10 ; a + + )
        printf ( " * " ) ;
    printf ( " \ n \ n " ) ;
    gotocoordinate ( 30 , 11 ) ;
    printf ( " Departmental Store " ) ;
//textcolor ( 1 ) ;
    gotocoordinate ( 32 , 17 ) ;
    printf ( " RECORDS " ) ;
//textcolor ( 8 ) ;
    gotocoordinate ( 18 , 23 ) ;
    printf  ( " SN   Item Name   Item Code   Rate   Quantity " ) ;
}

根据用户输入的商品代码，上述代码将显示结果。

void view ( record * stocks , int i , int j )
{
    gotocoordinate ( 16 , i ) ;
    printf ( " % 4d " , j ) ;
    printf ( " % 9s " , stocks - > name ) ;
    printf ( " % 12 s " , stocks - > code ) ;
    printf ( " % 14.2 f " , stocks - > rate ) ;
    printf ( " % 11d " , stocks - > quantity ) ;
}

以上代码将显示部门的商品。

void delete_stocks ( )
{

    char d [ CNN ] ;
    FILE * openfile , * openfile1 ;
    system ( " cls " ) ;

        openfile1 = fopen ( " record1.txt " , " ab " ) ;
        openfile = fopen ( " record.txt " , " rb " ) ;
        rewind ( openfile ) ;
        while ( fread ( & stocks , sizeof ( stocks ) , 1 , openfile ) )
        {
            if ( strcmp ( stocks.code , d ) ! = 0 )
                fwrite ( & stocks , sizeof ( stocks ) , 1 , openfile1 ) ;
        }
        gotocoordinate ( 27 , 29 ) ;
        printf ( " --- item deleted --- " ) ;
        remove ( " record.txt " ) ;
        rename ( " record1.txt " , " record.txt " ) ;
    }
    if ( flagerized = = 1 )
