​Lesson Objective

• Create a clear name for each variable

• Write an outline plan for a program

​Naming a variable

• Name must be meaningful and appropriate

• Correctly describes variable's purpose

• Can easily tell the difference between multiple variables

• Others can also understand what your program or algorithm is doing

Naming a variable

​Naming a variable

• Avoid use random numbers

​Importance of Planning a program

• To be clear on what exactly will be included in your program

• To have a simple overview of your program

​Steps to writing an outline plan

• Step 1 : Identify purpose of the program

• Step 2: Identify the events

• Step 3 : Identify expected outcome

​Subprograms

• are small programs that are part of larger program

• each event and outcome can be written as subprogram
