Students use an interactive animated slideshow to guide them through the process of programming a simple calculator with user inputs. Using C, the student will learn about variable definitions, assignments, format strings, scanf, printf, taking user input, simple storage, equality, and operations. This is part one of the tutorial. In part two, users will use if and while to create a loop. This is a great tool for the beginner computer programmer as it spells out in basic English what the code is actually doing. I made it easy understand for the novice learner.
