C++常见code!

1.Change values via pointer[^stackedit]. [/i] Settings .

void swap(int** p,int** q)

{

int* temp;

temp = *p;

*p = *q;

*q =temp;

}

//调用的时候—-

int* p,*q;

swap(&p,&q);

2.Input pointer String

#include<stdio.h>
#include<string.h>
#include "stdio.h"

int main(int args,char* argc[])

{

char s[255];

char *p=s;;

scanf(“%s”,p);

puts(p);

return 0;

}
