KHALID ANSARI December 25, 2011

first of all error occured is “function exit(0) must have prototype” but however if you will not include case 4 then it wud run but after running first you enter the choice 2 n see what happend..prog is not abs. right.
Dear uploader, upload absolutely right prog without any error..
