hi there, newish to C, need a little help *RESOLVED*

[Bond0r]

hi there, im creating a little proggy for uni and have come accross a couple of things i just cant find on the NET. so i thought id ask one of the pros, here it is....

btw, its a simple C dos window app thingy

1) me program has a few Yes/No questions and then 'IF' statements are based on the answers, how can i disable the keyboard only letting the user press the 'y' or 'n' key. My friend has it done, but wont tell me how.

2) is there a way to restart the app? it envolves the user inputting a set of questions (age, y/n Q's, etc) and then displays a summary (is this info correct), what i want to do is, if the user presses the 'n' key (as in, no the info is not correct) to restart the app from the beginning thus going throw the input stage again

i hope this makes sense, and i would be grateful if one of you guys could help me with this
