Loop on String

[Nobody/Anonymous]

I am trying to loop this program for a CS class of mine.  Everytime I try to do a do,while loop in the main part, it doesn't work. This isnt exactly a problem with Dev-C++, but i know there is someone here who can help.  Below is a copy of the program:

#include <iostream.h>
#include <stdlib.h>
#include <string>
//**********************************************************
void WriteFirstLast(){

string Name;
cout << "Enter name in Last, First format: ";
getline(cin, Name);
cout << Name << endl;
int comma = Name.find(",");
string Last = Name.substr(0, comma);
string First = Name.substr(comma + 2, 999);
cout << First << " " << Last << endl;
}
//**********************************************************
int main()
{
WriteFirstLast();
system("PAUSE");
      return 0;
}

// Start of Prog
#include <iostream>
#include <stdlib.h>
#include <string>
using namespace std;

//**********************************************************
bool WriteFirstLast()
{
  string Name;
  cout << "Enter name in Last, First format: ";
  getline(cin, Name);
  if (Name == "") // CLS If nothing is entered
    return false; // CLS Quit loop
  cout << Name << endl;
  int comma = Name.find(",");
  string Last = Name.substr(0, comma);
  string First = Name.substr(comma + 2, 999);
  cout << First << " " << Last << endl;
  return true; // CLS Everything A-ok
}
//**********************************************************
int main()
{
  bool success = true;
  while(success) // CLS Loop condition based on return val of WriteFirstLast()
  {
    success = WriteFirstLast();
  }
  system("PAUSE");
  return 0;
}
// End of Prog

By not entering anything and just hitting 'enter' the loop will exit.  I believe that this is what you were looking for.
