Hi, i'm new to c++. I understand the idea of functions, and i know that i have to declare them as rand. I think that you have to declare an argument, but i find the tutorial a little hazy. At the minute i am experimenting with the example on the switch/case page, which i have to declare playgame, loadgame and playmultiplayer as functions. I have declared them as rand's but it says it takes 0 argument, so i don't know what to type. Any advice?
