SECTION A: Problem Solving (Programming) (30 marks)
Problem : A “Njangi Group” in a certain community has decided to automate their financial processes, as a
result of the rapid increase in membership making manual processing of financial transactions difficult.
Financial transactions include: Checking members balance, Checking Eligibility for a Loan, Calculating
Interests, and setting deadlines for payments.
The management has decided to make life easy to both members and financial officers by developing a
Cash Dispenser Machine. Members can use this machine to check their balance, withdraw funds, check
their eligibility for a loan and so on.
“Aigcn Tech“, an IT startup company in which you work as a software developer has been given the Job to
develop a program for the Cash Dispenser System.
The System analysts have already done their Job by analyzing the requirements of the system and
documenting them in a Systems Requirements Specification Document.
As the lead Software Developer, your role is to coordinate the development of the required program for the
system. Each component of the softw are has to be implemented as described in the Software Requirements
Specification Document.
Go through the Work Breakdown Structure of the software Requirements Specification outlined below in
the form of tasks which you and your team are to carry out to complete the project.
Sample Data: Figure one below shows how each member in the “Njangi” has their first name and balance
stored separately with a matching unique PIN code known only by them. The figure 1 below‘ show‘s a
sample of how information about a few members is stored. The PIN Codes are shown in the figure as the
“indices”.
NB: 101 – 105 are Unique PIN codes assigned Each Member

A
| Balance | 10000 | 50000 | 25000 | 55655 | 1565785 |
| 101 | 102 | 103 | 104 | 105 | |
| Figure 1 |
The Array “Balance” has the corresponding account balance for each member as indicated with the PIN.
The follow‘ing Algorithms may be required for some parts of your solution.
| Algorithm 2 Variables: Balance[ ], Memberf ], PIN, Amount, loanAmount, Name, Option, K. //Inside your main program, do the following * Add program statements that prompt and allow a user to enter their PIN and Name * A *– Return value from Authentic function iF (A^irr REPEAT * Display Cash Dispenser Menu Options, i.e 1. Check Balance 2. Cash Withdrawal 3. Loan * Prompt and allow user to enter an option |
Algorithm 1 Function Authenticate(Array, PIN, Name) Boolean p = –1//assumed not authentic For i «–101to 105 Do IFArray[i] = Name THEN IF i = PIN THEN P = 111 authentic break End If End IF End For Return p End Procedure |
* SWITCH (option){
Case of Check Balance
Function call
Break
Case of Widthrawal
Prompt & allow‘ user enter withdrawal Amount |
