Monday (11/15/10)
Warmup:
- Assume you have the following code:
1 a = 0
2 b = 1
3 c = 0
4 a = a + 1
5 c = c + 1
6 b = a * c
7 c = c + 1
- What are the final values of a, b, and c?
Agenda:
- Introduction to Iteration (looping)
- while loops
- counter variables
- Looping practice
- Print out all the numbers from 0-50
- Print out all the numbers from 75 down to 25
- Write a loop that prints out the first 100 even numbers
- Prompt the user for a number and store it in a variable n, then print out the first n odd numbers (starting at 1) using a loop
- Print out all the numbers that are divisible by 6 from 0 through 100
