不使用算术、关系或条件运算符设置变量

2024 年 8 月 28 日 | 3 分钟阅读

我们有三个变量 a, b 和 c，任务是不使用任何算术、关系和条件运算符来设置 x 的值。我们需要遵循以下规则。

应遵循的方法

If c = 0
    x = a
Else // here, in this case, the c variable is binary
    x = b.

示例

Input: a = 5, b = 10, c = 0;
Output: x = 5
Input: a = 5, b = 10, c = 1;
Output: x = 10

算术运算符 C++ 代码

// here we are writing down the C++ programming language code to 
// demonstrate the concept of arithmetic operators
#include <iostream>
using namespace std;
// the main driver code functionality starts from here
int main()
{
	int JTP1, JTP2;
	JTP1 = 10;
	JTP2 = 3;

	// printing the sum 
	cout<< "JTP1 + JTP2= " << (JTP1 + JTP2) << endl;

	// printing the difference 
	cout << "JTP1 - JTP2 = " << (JTP1 - JTP2) << endl;

	// printing the product 
	cout << "JTP1 * JTP2 = " << (JTP1 * JTP2) << endl;

	// printing the division 
	cout << "JTP1 / JTP2 = " << (JTP1 / JTP2) << endl;

	// printing the modulo 
	cout << "JTP1 % JTP2 = " << (JTP1 % JTP2) << endl;

	return 0;
}

输出

JTP1 + JTP2= 13
JTP1 - JTP2 = 7
JTP1 * JTP2 = 30
JTP1 / JTP2 = 3
JTP1 % JTP2 = 1

关系运算符

序列号	关系运算符	运算符描述	示例片段
1	==	等于运算符	x == y
2	!=	不等于运算符	x != y
3	<	小于运算符	x < y
4	<=	小于或等于运算符	x <= y
5	>	大于运算符	x > y
6	>=	大于或等于运算符	x >= y

条件运算符

// here we are writing down the C++ programming language code to 
// demonstrate the concept of relational operators
#include <iostream>
using namespace std;
// the main driver code functionality starts from here
int main()
{

	// here, we are declaring the variables 
	int n1 = 5, n2 = 10, max;

	// using the relational operators, we are trying to find the largest one
	max = (n1 > n2) ? n1 : n2;

	// using the cout output statement, we are trying to print the largest one
	cout << "The largest number between " << n1
						<< " and " << n2
						<< " is " << max;

	return 0;
	// end of the program
}

输出

The largest number between 5 and 10 is 10

C++ 代码

// here we are writing down the C++ programming language code to 
// demonstrate the concept of Setting a variable without using Arithmetic, 
// Relational or Conditional Operator
#include <iostream>
using namespace std;
// function to calculate the value of x returned to the driver code call
int calc(int a, int b, int c)
{
	return ((1 - c) * a) + (c * b);
}

// the main driver code functionality starts from here
int main()
{
    // assigning the values of the variables
int a = 45, b = 90, c = 0;
	
int x = calc(a, b, c);
// displaying the output value returned by the calc function
cout << x << endl;
	
return 0;
}

输出

}

{
        // assigning the values of the variables
int a = 6, b = 7, c = 1;
	
int x = calculate(a, b, c);
// displaying the output value returned by the calc function
cout << x << endl;
	
return 0;
}
