In this tutorial, I have demonstrated such functions that have any valid return type but no parameter list with a proper coding example in C programming language. Functions that have a return type is said to have any valid data types written as the return type such as int, float, double, and char. It indicates the type of the data value that will be returned to caller function by the end of execution of the called function. If there is no parameter list of a function then void is written in the place of the parameter list.
