Iterative programs

Iterative programs are consistently reused steps within programming, the basic flowchart for iterative programs follows the steps below:

• Establish the variable we are going to use
• Initialize outside the loop
• Setup the right end test
• Construct the block of code 
• the set of instructions that will be done each time through the loop
• the variable must change each time or you will end up in an infinite loop
• What happens when the iteration is done

Defensive programming

• Assume that if you are getting inputs from a user, don't expect the user to give them what you want.
• If you are getting something from another part of the program or an external source, expect the source and information to not be as expected.
• Make sure that all possible paths through the code are accounted
• Make sure there is a possible path through
