LinuxQuestions.org - Please help find bug in my c++ program!

Hi,

I have made a small program that makes life a bit easier for people who
run game servers and lan partys in linux. The problem is i am having
problem working out what loop in my program is wrong, and i dont think it
is reading games.db from the correct part. The program should read the
games.db from the begging where the path is and then enter that directory
and execute the start script. The games.db looks like this :-

path;./startscript:gamename e.g /home/twirl/bf1942;./start.sh:Bf1942

The problem is i cannot see what loop in my program aint working correctly
from case 3, as it should cd into the directory and execute the script and
should print out errors if something aint right but it aint doing either.
Please have a look at my code below and help a newbie to c++ out. All your
help is very much appreciated! All code below compiles without errors

Code:

#include <iostream>

#include <fstream>

#include <string>

using namespace std;

 

int main()

{

 int i=0;

 char s1[80],s2[40],s3[90],s4[256],s5[90];      // set char size for input

 ofstream outfile("games.db", ios::app);

 string whole,p1,p2,p3;

 ifstream infile;

 

// Start Main Menu

 

 char choice='\0';//NULL;

 bool finished=false;

 while (finished != true) 

 {

  cout<<"MAIN MENU\n";

  cout<<"1. AddGame\n";

  cout<<"2. Options\n";

  cout<<"3. RunGame\n";
