C++常见code!

1.Change values via pointer[^stackedit]. 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; }
