Introduction

This Internal Assessment is a based on problem solving where the researcher has chosen a problem where the implementation of algorithms is used to find the solution. The problem developed is made so that the researcher can show the examiner the step by step procedure used to solve the problem. The problem developed was of the business Kool Kut Barbers where the problem entails the business trying to improve their profits and system which manages the efficiency of their services.

The Question (Requirements)

Each candidate is expected to choose a problem for which a software solution is appropriate and create algorithms for the solution using sequencing, assignments, and iteration ( bounded and unbounded). They should represent their algorithms using narrative format and either flow chats or pseudo code. Candidates are expected to implement their algorithms as C programs using arrays with no less than five functions and using at least one file. They must also create a test plan that is used to test their implemented programs for correctness.

Definition of Problem

The manager or owner of Kool Kut Barbers has a problem as his establishment is losing customers or sales due to the lack of organization in dealing with the customers. The employees have been faced with problems as the correct order in which the customers come, the prices which each individual should pay and the customers service selection are all time consuming to deal with each and every customer. The manager would like to develop a program or system where both customers and employees can log in. The system also has a price list of the services they give. The program allows one to log in state whether male or female as the prices for male and female trims differ. After ordering a service the system asks if the customer would like to add a pattern. The system logs the time and order in which customer come and also state which of the barbers will be serving them. There are additional options as to view the owner’s detail. When logged in as an employee you can access the customers information, the services they order, the time and the order in which they logged in and the total amount received from each customer.
