C语言基础(3)_指针

C语言基础(三)_指针
1.指针变量的初始化

#include<stdio.h>int add(int x,int y){return x+y;}void pfunc(int x,int y,int (*pf)(int x,int y)){printf("函数指针返回结果：%d\n",(*pf)(x,y));}void main(){/*指针数组示例*/int a[2][3],*pa[2];/*pa[0]=a[0];pa[1]=a[1];*//*二维数组行指针*/int b[3][4];int (*pb)[4];/*pb=b;*//*二级指针示例*/char *pstr[]={"one","two","three","four","five"};char **p;p=pstr;printf("二级指针返回结果：%s\n",*(p+1));getch();/*函数指针示例*/pfunc(3,5,add);}
