Notes to students:

1.See the attached video from class for revision if needed.
2.The demonstration files that were created are also attached to this post. (It’s posted individually as “Demo01.Fprg” and “Demo02-Looping (While Loop).fprg“.  Both of these files are packaged together in the zip, “Class Demonstration Files


Follow the example that was demonstrated in class today to :
1. Draw a flowchart which will output the cubes of the first 100 numbers
2. Write the pseudocode for the flowchart above.
3. Required reading for next class:

Repetition (Iteration) Constructs

Consider the following example:

Find the sum of 10 numbers provided by the user.

This can be accomplished as follows:

The above solution is very long as well as difficult to understand , manipulate and communicate .

Observe that there were many repeated steps in obtaining input from the user.

The solution can be simplified by looping.

A general looping construct is shown below:

The solution can be simply implemented using looping:

Class Discussion: walk-through of solution is discussed.
