getting “void value not ignored as it ought to be” in C

Question

I started learning C in class and have started the assignment but I'm writing it one piece at a time. Currently I'm stuck because I may be doing something completely wrong but I don't know what I'm doing.

Answer 1

The error is pretty clear... The void type isn't something you can return / store in a variable. Instead it's a special type that means "nothing". You can't store nothing, you must ignore the return or return something.

Answer 2

displayCard only displays the cards, it does nothing to define them, so you shouldn't be trying to use it to create your cards. Instead, think about what a "card" actually is in your program--what, for example, do you have to pass to displayCard in order for it to know which card to display?
