Functions - ## A function is a sequence of instructions with a name. ## When a function is called, the instructions are executed. ## When the execution of the instructions is complete, the function may return a value to the calling program. Function round - price = round(6.8275, 2) ## The function round is called with arguments 6.8275 ## and 2. ## round returns the number 6.83, which becomes the ## value of price. ## The computations within round are hidden from the ## calling program...

Functions - group of statements that exist within a program for the purpose of performing a specific task Divide and conquer - Instead of writing 1 large program, break it down into individual tasks. individuals or teams can works independently on separate tasks. Advantages of divide and conquer - Simpler for programmers code reuse better testing faster development void function - executes statements, nothing is put into it by the program, and it sends nothing back to the main pro...
