Simple Function Example Programs  In C++

Definition

A function is like a black box. It takes in input, does something with it, then spits out an answer.
We have some terminology to refer to functions:
  • A function, call it f, that uses another function g, is said to call g. For example, f calls g to print the squares of ten numbers.
  • A function's inputs are known as its arguments
  • A function g that gives some kind of answer back to f is said to return that answer. For example, g returns the sum of its arguments.

Syntax:

return_type function_name(argumnent)
{
// body Of the Function
}
