函数指针实例

#include <stdio.h>void fun1(void){printf("I`m fun1\n");}void fun2(void){printf("I`m fun2\n");}void fun3(void){printf("I`m fun3\n");}void fun4(void){printf("I`m fun4\n");}void fun5(void){printf("I`m fun5\n");}void (*s[5])(void) = {fun1,fun2,fun3,fun4,fun5};int main(){int i;void (*isr)(void) = NULL;//定义一个函数指针for(i=0;i<5;i++){isr = s[i];(*isr)();}return 0;}

注意：一定不要出现野指针
