Functions (C++) A function is a block of code that performs some operation. A function can optionally define input parameters that enable callers to pass arguments into the function. A function can optionally return a value as output. Functions are useful for encapsulating common operations in a single reusable block, ideally with a name that clearly describes what the function does. The following function accepts two integers from a caller and returns their sum; a and b are parameters of type int.
