Homework 3:

Simple Discrete Even Simulation Using Queues (C++)

The assignment:

Customers arrive at the bank to make deposits or withdrawals and are served by a teller.

The following information is kept in a structure about each customer.

1. A structure named customer contains at least the following information:

int ID; customerId;

customer first name // // as either an array of char or a string

customer last name; // as either an array of char or a string

double amount of deposit or withdrawal

char Transaction Type: Deposit or Withdrawal

int arrival time;

int service time

double Balance: Account balance

int TellerNo; // a value between 1 and 3

2. Create an input file containing the information of at least 35 customers.

3. Create an array of struct: read the customers data from the input file into the array.

4. Create a queue: you can use the standard library template for the queue or you can write your own code for the different queue operations. The queue stores data of type customer.

5. Also submit an output file of all output that is being sent to the console.

What to do:

You need to code at least the following functions:

I. Random number generator

II. Initialization function:

• initialize an int named timer= 0 ;
• initialize an int named clock = 0 ;
• initialize the number of transactions served by each teller to zero

1. Read customers data from the input file into an array of structures.

2. For each customer in the array,

a. Generate a random number between 1 and 3 representing the teller station number.

b. Generate a number between 1 and 10 and add it to the timer, then store it as

the arrival time value for the customer.

III. . Create the queue function

enqueue the customer structure into the queue

IV. Teller Function

4. Dequeue the customers one at a time from the queue and do the following:

a. Add the amount of deposit or subtract the amount of the withdrawal to/from the balance
