Can you tell me what's wrong with it because it's not running on visual studio and I need it right now???

That builds and runs fine. My guess is that it finishes very quickly because it can't find the datafile and you don't even realise it ran and finished.

If you want to see the message comment out line #27 exit(1);

In VC++ you can do the following to see where your program is running:

Add include statement:

#include<direct.h>

Then add the following code to "Payroll::Payroll"

char* buffer;
string curDir;

// Get the current working directory: 
if( (buffer = _getcwd( NULL, 0 )) == NULL )
{
      perror( "_getcwd error" );
}
else
{
    curDir = buffer;
    printf("Current Directory: %s \n", buffer);
    free(buffer);
}

Then change

from:

cout<<"Sorry Data File is not Found"<<endl;

to:

cout<<"Sorry Data File is not Found (" << curDir << ")" << endl;

Better yet, you can make the path of your input file fully-qualified to ensure that the file is where you expect it to be.
