I've posted my C code below for a card game (yep, i'm still on it). Now the neg() function is called from the turn() function. so using return; sends it back there, but i want it to go back to the start of the main function (basicaly start again). As with in the eval function i want it to go back to the beginning of the main function if the input is y.
Also when n is the input, i want the program to just print the line "ok see ya" then finish, but it keeps looping either to the turn function or the eval. :cry:
ignore the "path" bits and functions for now. that's for when images are used in java..
