Question 2 (Marks: 50)
The system to be developed for Williams and Son needs to produce the following slip for a
customer once the sale has been concluded.
Please note: For the purpose of this assignment, assume that a customer will only purchase one
unit of each item.
Q.2.1 Write the pseudocode that will produce a slip similar to the one illustrated at
the beginning of the question. Your solution should satisfy the following
requirements:
The solution must illustrate the use of good programming practices;
The solution must make use of a loop;
The loop must make use of a sentinel value.
(22)
Q.2.2 The mainline logic of almost every procedural program consists of three parts
namely housekeeping tasks, detail loop tasks and end-of-job tasks. By making
use of flowcharts, show how these parts can be implemented in your solution
for Question 2.1.

B. They are exactly the same a while loops.
hint: google for loops vs while loops
C. On each iteration of the for loop, the indexing variable usually, $i, if always incremented by 1
D. $i++ means $i = $i + 1
