Really simple question, can't seem to find an answer. How do I do anything with a return value from a function. For example, I want to check the value of the return value with an if statement, what is the name of that which I should be comparing?
Code:void something (blah, blah2) { ...some code here... return 5; } int main() { something (5, 7); if ( ??? == 5) { ...some code here... } }

First of all your type signature is wrong for returning an integer. Try
Second you have to have a variable to receive the output of your function (in most cases).Code:int something (int a, int b) { return(5) ; }
You should give your C book a read now and then, or even try some of the tutorials.Code:int y = something(5,7) ; if (y == 5) { }
I was just painting in wide strokes so I forgot to add the types.Originally Posted by SevenThunders
Putting a variable to capture the return value is what I was looking for. Thanks!
or
Code:if (something(5, 7) == 5) { ... }
