The Five Steps - Step 4

Understand the problem

Do a small example by hand

Write an algorithm for solving the problem

Translate the algorithm into a programming language (like C)

We know that a C program is a collection of functions. For such a simple algorithm, we only need a single function. Since every C program must have a function main(), we can implement the algorithm by defining main().

Note: before even writing any code, we have included documentation in our program file in the form of comments

How do we define a function?

Defining a function in C consists of 2 parts - the header, and the body:

Test the program
