5. Iteration with Programs and Classes

More Looping: Math Tables
formerly got PhD for better tables
pow1.cpp
pow2.cpp
The Fence Post Problem

for Loop Syntax

for ( initialization; logical expression; update )
{
      statement list 
}

Use where number of iterations is "known"

Good for most examples shown previously

Class: Modify blastoff.cpp
Problem: Adder Program
- while or for ?
adder.cpp
Defining Constants
const type identifier = value;
all caps
Pre-tested and Post-tested Loops
Iteration (post-tested)
- loop test

do-while Loop Syntax

do
{
       statement list 
}
while ( logical expression );

Using the do-while Loop
addwhile.cpp
Infinite Loops
break Statement
Nested Loops multable.cpp
nesting can be hidden by using function
Scope of Variables
- Global Variables (XXX)
