Why int main and not void main?

Question

Void main just seems a lot easier. Idk. I feel stupid asking this.

Answer 1

Native applications are generally expected to return a value to the operating system. This allows shell scripts to branch based on your application's return code.

In windows/MS-DOS you can see that code with:

echo %ERRORLEVEL%

In Linux or MacOS, you can see the exit code with:

echo $?

For some applications this might not matter. If you write an app that might be called in a shell script, the exit code can be helpful.
