Hello-World

At the end of this lesson you will be able to write a program that will use while, do, and for loops. You will know the difference between a for, while, and do loop.

1. Print and read the lesson. (Punch, staple, put in your binder.)
Loop Lesson 2: while and do loops

2. Run each of the programs from the lesson, work with the flowchart if one is provided:

While1: print 0 1 2 3 4 5
While 2: print 0 1 2 3 4 5 using ++
Blast OFF: using a while loop
Average: using a while loop until negative number is entered. Flowchart
Total2: just 2 variables Flowchart
Total3: using a for loop to read 3 numbers Flowchart
Total4: uses a for loop to read N numbers Flowchart
Do Average: uses a do loop to find average Flowchart
Fahrenheit to Celcius: Flowchart

• Run the flowchart (if provided) to help understand the logic.
• Copy the program, paste it into your C++ compiler and run it..
• Experiment with it: make little changes and see what happens, make sure you understand it.
• Erase it - now try to write it without looking at your notes!

3. Using the sample programs as a model, write a program that will loop to input numbers. Print the total, count, average, smallest and largest.

Follow good programming habits:

• Indent each statement inside the curly braces about 2 spaces. All of the statements should line up.
• Use good variable names and comments: if you look at the program in a year, will you know what the program does?
