What is the function of a parameter?

A parameter is a named variable passed into a function . Parameter variables are used to import arguments into functions. Note the difference between parameters and arguments: Function parameters are the names listed in the function’s definition.

When calling a function with a function parameter, the value passed must be a pointer to a function . Use the function’s name (without parentheses) for this: func(print); would call func , passing the print function to it.
