ofstream doesn't create file in C++

Question

I'm trying to output every element of my array into a .txt file but for some reason it doesn't even create the file. I have both a cmd output and file output in my display method which is called from the main. The cmd output works perfectly but when i use ofstream to try and create a file and output the array's element to it, i don't see any text file created.

ofstream ofs("TEST.txt");

if(!ofs)
    cout << "cannot use" << endl;
else
{
    for(int a=0; a < 12; a++)
    {
        for(int b=0; b < 12; b++)
        {

            cout << RandomArray[a][b] << "\t";
            ofs << RandomArray[a][b];
        }

        cout << "\n";
    }

}

ofs.close();

try this

#include <iostream>
#include <fstream>

#ifdef _WIN32
#include <windows.h>
#define SYSERROR()  GetLastError()
#else
#include <errno.h>
#define SYSERROR()  errno
#endif

int main(int argc, char** argv)
{
    std::ofstream of("TEXT.TXT");
    if(of.is_open())
    {
        of<<"Some text here"<<std::endl;
        of.flush();
        of.close();
        std::cout<<"wrote the file successfully!"<<std::endl;
    }
    else
    {
        std::cerr<<"Failed to open file : "<<SYSERROR()<<std::endl;
        return -1;
    }
    return 0;
}

The win32 GetLastError() #define isn't tested, as I don't have a windows box handy. The errno bit works. this will at least tell you what the error is if the file open fails

Your program is okay, it should work so long as ofstream can be created. I think that you are not looking in the right directory.
