Programming Fundamentals [C Language] by: SHAH NAWAZ,UoG,Lahore The function and simple recursion 21-Topics Covered : Using more than one function, What is recursion?, Recursion vs iteration Using more than one functions C language allows to use more than one functions in one C program. All then functions will have their own declaration, definition and call. E.g #include<stdio.h> #include<conio.h> void one() void two(); void main() { clrscr(); one(); getch(); } void one() { printf (“This is function one”); two(); } void two() { Printf (“\nThis is function two”); } Output This is function one This is function two

In programming languages, if a program allows you to call a function by itself, then it is called a recursive call of the function and this technique is known as recursion. A useful way to think of recursive functions is to imagine them as a process being performed where one of the instructions is to "repeat the process". This makes it sound

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
