https://www.nowcoder.com/practice/2c577d21ca334724aa5807744256b6f2
#include <iostream>
using namespace std;
void swap (int *a, int *b)
{
int tmp = *a;
*a = *b;
*b = tmp;
}
int main() {
int a = 0;
int b = 0;
cin >> a;
cin >> b;
//write your code here.......
swap(&a, &b);
cout << a << " " << b << endl;
return 0;
}
使用指针进行操作，指针交换是个很常见的题目，要好好掌握
