1. Design and Implementation

2. Four Steps to Programming
Read
Design
Implement
Test

3. Program
A program is a list of instructions (actions) to accomplish a task.
Each instruction is an action to be performed with a program.
The process includes the four steps:
Read a scenario
Design a storyboard
Implement the code for the program
Test the program

4. Read
Is the description of the story, game or simulation, often called the “problem statement.”

5. Design How to go about creating the animation or program
Usually includes a flowchart
A form of communicating a programs design or a programs sketch.

6. Flowcharting
The best way to communicate a programs design is to create a design sketch or a visual system.
Flowcharts are constructed using a basic collection of symbols and are related to the actions that occur as the program runs.

7. Flowchart Symbols and Details
terminal
processing
Represents an action where the
User of the program is being asked
Information or a result is displayed:
Words associated w/symbol: read,
Print, and write.
Represents the beginning and
ending of a complete program:
Words associated w/symbol:
start, begin, end, stop and return
Used to illustrate mathematical
Operations, or built-in instruction
Or statement.
Input/output
decision
call
Represents an action where a decision is to
Be made. The outcome of a decision is a
Boolean value, which is either true or false.
Words w/symbol express the condition or test.
Represents the action of one piece of a
program calling another piece of the program.

8. Test Implementation The written code of a program
Running the program for errors.
Errors in computer programs are generally referred to as bugs. Correcting errors in a program is debugging.

9. Other Terms Algorithms: A textual storyboard.
Comments: Used to describe what a program is designed to do.
Functions: A math operation on numbers or other kinds of values.
Expression: A math operation on numbers or other number or other kinds of values.

10. Control Statements or Control Structure
Do in order
Do together
If/Else: A conditional execution control structure used to make a decision about whether a particular section of s program will be executed.
Loop: a repetitious control structure that is used to repeat a section again and again.
Do while
For all in order

11. Control statements can be nested meaning that one program statement can be written inside another.
