隐含的功能错误声明 [英] Implicit Declaration of Function Error

问题描述

我对编码很新，所以这是一个新手问题。我正在尝试使用函数而不是main来打印横幅：

Hi, I''m very new to coding, so this is a newbie question. I''m trying to print out a banner using functions instead of main:

展开 | 选择 | Wrap | 行号

推荐答案

As据我所知，函数被调用并在那里正确定义（虽然我认为你不需要参数列表中的''void''）。您是否在您的包含（主要上方）下定义了原型？你也声明int main但不返回任何东西。尝试添加''返回0;在你的banner1（）调用之下。

As far as I can tell, the function is called and defined properly there (though i don''t think you need the ''void'' in the parameter list). Do you have a prototype defined under your includes (above your main)? You also declare int main but don''t return anything. Try adding ''return 0; below your banner1() call.

我包括iostream，iomanip和cmath（整个程序很长，但横幅是现在的保留）。


我添加了return 0;，但结果与之前相同。

I include iostream, iomanip, and cmath (the entire program is pretty long, but the banner is the holdup for now).

I added "return 0;", but with the same results as before.

您是否添加了原型并从中删除了实现的参数列表？

Did you add the prototype and remove void from the parameter list of the implementation?
