Document Summary

Week 4 - lecture 6 - user-designed functions. A function is a way to group statements together and give them a name. It collects all the steps into one convenient place. Don"t refer to a recipe by its ingredients and steps. Instead you refer to it by its name. You solve a small piece of a problem once and then turn it into a function. Then you can use it whenever and wherever you want. Then other programmers have access to that solution and can refer to it by name instead of re-solving the problem. No language has all the built-in functions that you"d ever need, so every language gives you the ability to create your own functions. Make you own functions in order to write well-designed programs. Name can be any valid identifier(i. e. , same as a variable name) Parameters are unknowns(use none if there is no need; still need parentheses) Body can be any group of statements.
