#include<stdio.h> void function1(void); void function2(void); int main (void) { printf("for he is a jolly good fellow!\n,for he is a jolly good fellow!\n"); function1(); function2(); return 0; } void function1(void) { printf("for he is a jolly good fellow!\n"); } void function2(void) { printf("which nobody can deny!\n"); } 从哪里学的语法~~ 实践前也得学习才有效果~~

你函数定义有问题，应该把类型写在前面，声明带分号。 。

关注c语言基础

[小灸舞]

函数声明末尾要加分号
调用函数的时候要有括号
函数的实现要用大括号括起来
