Hi guys,
I have a technical question. How do I see if the user's input is a number?
So for example, when they type in 6,4 how can I get both 6 and 4 to store it in two variables?
I tried to implement this using a if statement like so : if(input == %d%d) but I guess it doesn't work like that.
Help please?
Read it in as a string, tokenize and parse it, and see if it matches the type of input you expected. If there is even a small deviation, discard the input and replace the user.

type.h is your friend.
Also, scanf can scan multiple variables in a specified format. Google it up!
