Question

How does a value-returning function differ from the void functions?

Answer 1

Void functions are made and utilized simply like value-returning functions aside from they don't restore a value after the capacity executes. In lieu of an information type, void functions utilize the watchword "void." A void capacity performs a task, and afterward control returns back to the caller- at the same time, it doesn't restore a value. You could possibly utilize the return articulation, as there is no bring value back. Indeed, even without the return statement, control will re-visitation of the caller naturally toward the finish of the capacity. A decent usage of a void capacity is print a header/footer to a screen or file. Interestingly, a void capacity (technique or method, in different dialects) doesn't restore a function value. Nor is it called from inside an articulation. Rather, the function call shows up as a complete, independent statement
