// Example 6-1：函数 swap(): 交换两个整形变量的值
#include <iostream.h>
void swap(int *xp,int *yp)
{
	int tmp;
	tmp = *xp;
	*xp = *yp;
	*yp = tmp;
}
// 试验函数swap()用的主函数
void main()
{
	int x = 2, y = 3;
	cout << "x = " << x << ", y = " << y << endl;
	swap(&x,&y);
	cout << "After exchange x & y:" << endl;
	cout << "x = " << x << ", y = " << y << endl;
}
