Logic To Find Biggest of 2 Numbers using Function

We ask the user to enter 2 integer numbers. We pass those 2 integer numbers to user defined function biggest. Inside function biggest we use ternary operator to determine the biggest number. Function biggest returns the biggest of the 2 numbers.

x>y?x:y

Here if x is greater than y, x will be returned else y will be returned.

Note: Function biggest returns integer type data. And it takes 2 arguments of type integer. We’re calling function biggest from inside printf() function.
