Assignment #: DC04
Assignment: Recipe Pseudocode & Flowchart
Due: Start of class - Oct 6/99
Marks: 10 marks

PART A: Design a program in pseudocode that describes how to prepare your favorite recipe. After typing the
recipe, do the following:

• Make sure everything is broken down into a number of steps

• Number each of the steps

• Indent/nest where necessary (in loops, conditions, etc.)

PART B: Develop a flowchart to graphically represent the control structure of your program.

Assignment Background Info

Sequence: Instructions typically follow a particular sequence. Computer instructions must be explicit.

1. Get cup

2. Pour Tea

3. Drink Tea

Repetitions: Sometimes steps are repeated. "Pour hot tea into each teacup"

REPEAT
    GET a NEW teacup
    pour the hot tea INTO that teacup
UNTIL the teapot is empty OR there are no more teacups available

Selection/Conditional: Computer can make choices

IF milk wanted, do this:
    add milk to tea
ELSE, do this:
    add nothing

Key words to capitalize: 

FOR EACH, REPEAT, UNTIL, WHILE, IF, THEN, ELSE, SELECT FROM, NEW
DELETE, PUT, GET, INTO

Example (to make tea):
