a、b、c 三个变量，通过引用按顺序循环替换他们的值。

实例

include

void cyclicSwap(int a,int b,int *c);

int main()
{
int a, b, c;

printf("输入 a, b 和 c 的值: ");
scanf("%d %d %d",&a,&b,&c);

printf("交换前:\n");
printf("a = %d \nb = %d \nc = %d\n",a,b,c);

cyclicSwap(&a, &b, &c);

printf("交换后:\n");
printf("a = %d \nb = %d \nc = %d",a, b, c);

return 0;

}
void cyclicSwap(int a,int b,int *c)
{

int temp;

// 交换
temp = *b;
*b = *a;
*a = *c;
*c = temp;

}
输出结果为：

输入 a, b 和 c 的值: 1 2 3
交换前:
a = 1
b = 2
c = 3
交换后:
a = 3
b = 1
c = 2
