// myVoid 等价于 （*pf）void myVoid(char *);void (*pf)(char *);// 声明函数的形参为另一个函数void show(void (*fp)(char *),char *c);//创建函数指针数组typedef void(*ppf)(char *);

//数组函数元素void myVoid2(char *);void myVoid3(char *);ppf bb;int main(int argc, const char * argv[]) {        //因为 myVoid等价于 pf，这里赋值后，下面函数的实参传入 pf函数就等于 把 myVoid函数传入    pf = myVoid;    char myChar[] = "my char";    show(pf, myChar);    show(myVoid, myChar);            //函数指针数组 初始化    ppf bb[3] = {myVoid,myVoid2,myVoid3};    for (int i = 0; i< 3; i++) {                char a[10];        sprintf(a,"%d",i);        show(bb[i], a);    }        void (*addPtr)(char *) = myVoid;    addPtr("dsfsadf");        return 0;}void myVoid(char *a){    puts(a);    }void myVoid2(char *b){    puts(b);}void myVoid3(char *c){    puts(c);}void show(void (*fp)(char *),char *c){    char *str = c;    //调用 myVoid（char *a)函数    //(*fp)(str) 等价于 fp(str)//    (*fp)(str);    fp(str);}
