A function declaration without a prototype is deprecated in all versions of C

[PeterMartins18*]

Hi There folks,

Someone can help me out here?
I am learning how to program "C" on Xcode and it is showing this problem all the time.
maybe someone knows what the problem is?

Thanks, Peter.

this a really old question, but is the empty argument list.

the compiler is expecting:

int main(void)
{
...
}

Hello luchifer ,

it could be the parser for syntax throwing an error.

// try with 'hard' semantic :

int main(){ // "{"" is next to the closing )    , the compiler won't warn anymore.

    // all code lines before achieving by 'return' instruction.
    return 1;
    // as you define main() function by 'integer Type', you must "return 0|1" ;

}
