C and C based languages - A first practical program

A first practical program - C and C based languages module C202

Programs store information in variables, and we'll look at how these are declared, initialise and used for calculation in C. We'll also look at reading inputs from the user and writing information back out so that by the end of this module you'll have written a simple but practical program in C.
