交换a与b的两种实现方法

1. 使用逗号表达式交换变量值

在C语言中,使用逗号表达式可以实现多个变量的交换操作。这种方法简洁且高效,适用于代码简化需求。

int main(){    int a, b, t;    printf("输入a和b值: ");    scanf_s("%d %d", &a, &b);    t = a, a = b, b = t;    printf("交换后的值: %d %d\n", a, b);}

2. 使用赋值语句交换变量值

另一种常用的方法是使用赋值操作符逐个交换变量值。这种方法的逻辑清晰,易于理解。

int main(){    int a, b, t;    printf("输入a和b值: ");    scanf_s("%d %d", &a, &b);    t = a;    a = b;    b = t;    printf("交换后的值: %d %d\n", a, b);}

测试结果示例

输入a和b值: 10 30

交换后的值: 30 10
