You may be capturing the directory using _getcwd . You can store it in a variable and call it as you need it. getcwd is a POSIX function that is compiled by all POSIX-compatible platforms. you will only need to include the headers Unist. d in UNIX and direct. h in the Windows

A Case:

#include <stdio.h>
#ifdef WINDOWS
   #include <direct.h>
   #define Define_CurrentDir _getcwd
#else
   #include <unistd.h>
   #define Define_CurrentDir getcwd
 #endif

        char LOCAL_DIR[FILENAME_MAX];

         if (!Define_CurrentDir(LOCAL_DIR, sizeof(LOCAL_DIR)))
             {
             return errno;
             }

        std::cout << "Diretorio: " << LOCAL_DIR;

For Windows system you can use the function GetModuleFileName() passing the parameter hModule a null value. Something like this(not tested):

#include <iostream>
#include <Windows.h>

using namespace std;

int main ()
{   wchar_t buffer[MAX_PATH]; 
    GetModuleFileName(NULL, buffer, MAX_PATH) ;
    std::cout << buffer << std::endl;
    cin.get();

}
