Document Summary

Function: a group of statements that exist within a program for the purpose of performing a specific task. If a function doesn"t return anything, you must have a print statement. A function that does not receive any arguments and does not return any values. A function that does not receive any arguments but returns value(s) A function that receives arguments but does not return any values. A function that receives arguments and returns value(s) Modularized program: a program that has been written with each task in its own function. Defining a function specifies what it does. We must call a function to execute it. Hierarchy chart (structure chart): shows boxes that represent each function in a program. Local variable: assigning a value to a variable inside a function. Only statements inside that function can access the variable. An error will occur if a statement in one function tries to access a local variable that belongs to another program.
