What is wrong with this program?

[Prongs298]

it exits after i enter the choice of the menu item..

People here would be able to better help you if you explain to them what problem you are facing.

 

[gameranand]

Do you get to enter the number or not ??

 

[krishnandu.sarkar]

scanf("%c",v2); => scanf("%c", &v2);

 

[Prongs298]

scanf("%c",v2); => scanf("%c", &v2);

yeah mate that was it. i figured it out myself also. and that was fifteen minutes after posting it her. its embarrassing.

just tell what problem you are facing... nobody has time to read whole code.
