cout<<"Each player is asked to bet a certain amount of cash before a round of dealing starts. He/She may bet anywhere between 50$ to how much ever they have left in their account."<<endl;

cout<<"\n\n DEALING PATTERN..."<<endl;
cout<<"\n= The aim of this game is too get a sum total of 21 from your cards. If a Player's dealt cards sum up to 21 , Then he straight away wins that round."<<endl;
cout<<"= Firstly,each player gets a 2 alternate chances to generate 1 card out of the deck , by saying'HIT' when it is his/her turn. After two turns each, each player has two cards and then the play goes to Player 1 to continue with the 'HIT' or 'STAY-( STAY-which means that the player is satisfied with the dealt cards and wants to stop 'HITTING'."<<endl;
cout<<"\n\n Once Player 1 decides to 'STAY', It is Player 2's turn to 'HIT' or 'STAY'.He/She may continue to do so until he/she is also satisfied with the cards dealt."<<endl;
cout<<"\n \n= After both the players have stopped with the dealing of the cards, The sum total of their respective cards is calculated and the player with the highest total wins that round.But there are certain rules regarding who wins and who loses."<<endl;
getchar();clrscr();
cout<<"\n\n HOW DO YOU WIN A ROUND OF BLACKJACK...?"<<endl;
cout<<"\n= The scoring system goes like this:-\nAce- 1point\nFace cards-10 points\nRest of the cards- Points=the face value of the card"<<endl;
cout<<"\n The player's whose points add up closest to 21 , but not greater than 21, wins the round."<<endl;
getchar();clrscr();
cout<<"\n\n WHAT IS A BLACKJACK...?"<<endl;
cout<<"\n= When a player's points on the cards add up to a 'Perfect 21' , He/she is said to have got a Blackjack! and wins the round."<<endl;
cout<<"\n\n WHAT IS A BUST...?"<<endl;
cout<<"\n= When any player's points sum upto greater than 21, He/she is BUSTED and loses that round. "<<endl;
cout<<"\n\n Thus , the 'WINNER' of the game Blackjack is the one who beats the other player in terms of account balance."<<endl;

You need to be specific about what the issues are. As the great (moderator) WaltP will tell you, "we're not mind readers."

The account delete is not working. The logging in doesn't work. I think the create function itself is creating a doubt.

Line 60,122,123 (etc) never use gets. You can overrun your buffer and crash your program. The gotos make everything a little sloppy.
Can you elaborate more on those issues? What about it doesn't work? Is it the file reading or the password matching? You can shed some light on these issues by running it through a debugger or by cout'ing your variables along the way.
