CPS 6, Ramm - Summer Semester I - 5/26/00 #7

Chapt 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; test expression; update) { statement list
}
- Good for most examples shown previously
Class: Modify blastoff.cpp
Problem: Adder Program

Add an unknown number of numbers
When to quit
Sentinel Value
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 ( test 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)
Random Numbers & N-sided Dice: Simulations
Class: dice
- Behavior
Using dice
roll.cpp
Class Diagram
- Private
  - member functions
  - data
Constructors
The Dice Interface
dice.h
"Declaration" not code (not Definition)
Dice Implementation
dice.cpp
Iteration (pre-tested)
- update
Dice/While Example roll300.cpp
modify to use for loop
