Hello Computer Science: Loops in C++

1. Print and read the lesson. (Punch, staple, put in your binder.) Lesson 1: for loops

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

Total1: no loop 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
Blast Off!: loop to print numbers
Count by 5: using a for loop
Powers of 2: for loop print 1 2 4 8 ...
Count by .5: for loop to print 1 1.5 2 2.5, etc.
Fractions: for loop to print 1/N
Alphabet: use for loop to print the alphabet
Binary: convert integer to binary. Optional: Lesson on binary numbers.

To get the most out of these programs

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!

4. 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?
