i wish to modify this kbc like code n provide the option of PLAY AGAIN and QUIT to the user. if the user chooses to play again, a different set of questions is to be displayed. here is the code...

This is not how you should be doing it. You should use the files to store the questions options and the answer.
changes for main(): even if you dont want to totally change the look of the program you can define a Code: void question(int question_number) function containing all the questions you want. now there should be a question_counter in the main() and you will need to pass the value of it in the function question(). changes for question(): use condition based on the ques no.(if-else or whatever you like) to run the part of the code related with that code number. at last you can print "do you want to continue... blah blah" and scan the choice. check the choice(yes or no) and use Code: goto start; accordingly by condition checking. type Code: start: in the starting part of the code wherefrom you want to repeat the whole thing. warning: everyone will tell it is better not to use goto for good programming. so alternatively you can use loop within the main(). thats it. when you finish it you plz post the code here or email me abhasbhattacharya@gmail.com as you like. i will try to fine tune it.
