C_利用函数的引用调用实现两数的交换
源码：
# include <stdio.h>
void swap(int *x, int *y);
int main()
{
int i, j;
i = 12;
j = 36;
printf("i and j before swapping: %d %d\n", i, j);
swap(&i, &j); // 传递变量i和j的地址，深刻理解此时：&i为变量的地址，而i为变量（值）
// 调用swap函数的传递过程为：x=&i ; y=&j ;
printf("i and j after swapping: %d %d\n", i, j);
return 0;
}
void swap(int *x, int *y) // 深刻理解此时：*x为变量（值）而x为指针（地址）
{
int temp;
temp = *x; /* 存储变量x的值 */
*x = *y; /* 将y的值放入到x中 */
*y = temp; /* 将x的值放入到y中 */
}
