我的尝试：



我将main（）更改为int main（void）但不起作用

What I have tried:

I change the main() to the int main(void) but it not worked

推荐答案

main 需要返回一个整数值：它应该如下所示：

main needs to return an integer value: it should look like this:

#include <stdio.h>
int main()
{
   ...
   return 0;
}

零表示未发现错误 - 任何非零值都是错误代码。

The zero means "no errors found" - any non-zero value is an error code.
