有12个温度数据，用指向二维数组的指针求平均温度

#include "stdio.h"
void average(float *p,int n);
void print(float (*p)[4],int n);
void main()
{
  float t[3][4]={12,22,45,12,23,23,45,33,56,23,12,56};
  average(*t,12);
  print(t,2);
  return 0;  
}
void average(float *p,int n)
{
  float sum=0,aver;
  float *q;
  for(q=p;q

利用字符指针变量输出一个字符串和该串的第四个字符

#include "stdio.h"
void main()
{
 char *p="i love you !";   
 printf("%s\n",p);
 printf("%c\n",*(p+3));
 return 0;
}

给定一串字符，输出给定n 个字符后的字符

#include "stdio.h"
void main()
{
 char *ps="sdgdbhs";   
 int n;
 scanf("%d",&n);
 ps=ps+n;
 printf("%s\n",ps);
 return 0;
}
