1. Program Options: 10 Minutes online
Write a program that will display your home address as it would on an envelope.
First Name Last Name
Address
City, State Zip Code
Push: Let the user enter some or all of the information, and have your program format it.
Write a mad-lib program
Have the user enter at least 4 pieces of information.
Noun, Adverb (honestly), Adjective (messy), Verb, Geographical location, …
The computer will generate the mad-lib
Here is a sample website
Write a program that shows a poem or song. Can be an original work. Include space as appropriate.
Push: Look up for..do, or repeat..until to have your program repeat the song several times.
Push: Use the Pascal tutorial to add color etc.

7. Math Math Pascal Code Example + Ans:= first+second; -
Ans:= second – first; x *
Ans := first * second; ÷ /
Ans := first / second ()
Ans := (first + 2)/second; π PI
Ans := PI; 52
sqr
Ans := sqr(first); √
Sqrt()
Ans:= sqrt(first);

16. Sample program Input: The radius and height of a cylinder. Process:
Surface area = 2πr2+2 πrh
Volume = πr2h
Output: The Volume and surface area of the cylinder.

17. Hands on Test: Radius of 1 inch and height of 1 inch
Surface area = πr2 + πr2 +2 πrh
Volume = πr2h
Test:
Radius of 1 inch and height of 1 inch
Radius of 2 inches and height of 10 inches
