c语言之函数指针

定义：指向函数的指针：函数指针

函数：void printFuction()

函数指针：void(*ptf)()

赋值：ptf=printFuction(ptf=&printFuction)c语言规定：当用函数名（printFution）来初始化函数指针时，函数名会被转换为指向这个函数的指针

#include<stdio.h>
void printFuction(){
printf("test ptf\n");
}
int main(){
void (*ptf)();
ptf = printFuction;//ptf=&printFuction;
printf("ptf()\n");
ptf();
printf("(*ptf)\n");
(*ptf)();
return 0;
}
