How to use nested functions in C Programming

A function calling another function within its function definition is known as a nested function. So, far we are declaring a main function and calling other user-defined functions and predefined functions like printf, scanf, gets, putsetc., So, main function can be treated as a nested function. Let’s see the following example: In the above example, the main function is calling three functions namely: clrscr, func1 and getch. So, main is a nested function. Also, in the definition of func1, it is calling another function func2. So, func1 is also a nested function. Note: In programs containing nested functions, the enclosing
