C语言代码：计算两个整数的和与差

#include <stdio.h>

int main() {
    int num1, num2, sum, diff;
    
    // 输入两个整数
    scanf('%d %d', &num1, &num2);
    
    // 计算和与差
    sum = num1 + num2;
    diff = num1 - num2;
    
    // 输出结果
    printf('The sum is %d and the difference is %d.', sum, diff);
    
    return 0;
}
