所以我现在正在学习用C语言编程。我们正在与ubuntu合作,所以我在家里安装了一个,但是我在编译时遇到了很多问题。
使用gcc file_name.c编译我的
这是我的代码:
#include <stdio.h>
main (){
printf ("hello world\n");
}
但问题是,它给了我这种类型的错误:

我做错了什么? ty提前为你的时间
答案 0 :(得分:1)
请尝试:
#include <stdio.h>
int main()
{
printf ("hello world\n");
return 0;
}
编辑使用:
gcc file.c -o compiledFile
答案 1 :(得分:0)
main
确实应该返回int
,但是编译器安装似乎存在问题。虽然你没有修复它,因为你做的很简单,你也可以使用在线编译器,如http://www.tutorialspoint.com/compile_c_online.php
它非常易于使用。
答案 2 :(得分:0)
所以伙计......我搜索了一下,我发现我需要安装它:
sudo apt-get install mingw32
执行此操作后,gcc file.c命令工作,并创建了一个a.out文件
之后它工作得很好。 所有的时间和消息!答案 3 :(得分:-1)
请改为尝试:
#include <stdio.h>
int main(void)
{
printf("Hello, world!\n");
return 0;
}
答案 4 :(得分:-4)
您应该在程序结尾处输入void
或int
并返回值:
void main() {
}
或
int main(void){
return 0;
}
并使用Visual Studio。它更好:))
