C compile error: Id returned 1 exit status

Question

For some reason, when I try compiling a program, the compiler says permission denied and Id returned 1 exit status. Could anyone tell me what that means? Thank you

This answer is written for C++ developers, because I was haunted by such problem as one. Here is the solution:

Instead of

main()
{

}

please type

int main()
{

}

so the main function can be executed.

By the way, if you compile a C/C++ source file with no main function to execute, there will definitely be a bug message saying:

"[Error] Id returned 1 exist status"

But sometimes we just don't need main function in the file, in such a case, just ignore the bug message.
