LNK2001 error on atoi and stoi function with proper includes added

I have this project that throws LNK2001 error on using atoi while proper includes added:

#... //other headers
#include <cstdlib>
#include <string>
#include <cstring>
#include <cstdio>
#include <sstream>
#include <iostream>

BOOL main(int argc, char* argv[]){
    ShowNumber(atoi(argv[1]));
    return TRUE;
}

Error is: LNK2001: Unresolved external symbol _atoi

I do know that LNK error happens while a header confusion occurs. But i don't think that headers are the problem here. Is there anything in the project configuration or header conflict that may cause this to break? Also i get 15 other LNK2001 on using std::stoi.

Visual studio 2017 with 2015 or 2017 toolset.

`BOOL` being just a typedef for `int`, why not use actual `int` as is standard? – Davis Herring May 19 '19 at 20:25
@DavisHerring You are right. But i thought it might be cleaner this way. I don't think it affect performance. – 0_o May 20 '19 at 10:17
I would call it less clean (and needlessly Windows-specific), but it certainly doesn’t affect performance. – Davis Herring May 20 '19 at 10:52
