Question

Plz do it in c++ language

Define a class named FCFSQueue with two private attributes:
CustomerList: an array of 100 elements of type Customer;
length: integer, which is the number of customers in the queue.
And four public methods:
1. method IsEmpty checks whether the queue is empty or not. Return true if empty, otherwise, return false;
2. method GetLength will return the number of customers in the queue;
3. method Enqueue will insert a new customer to the tail of the queue;
4. method Dequeue will remove a customer from the head of the queue.
And 1 constructor:
1. Default: where you will initialize length
Problem 2
Implement all methods for Problem 1and test them in your main function by creating an FCFSQueue object calling methods on it.

In this program, you will implement a FIFO or FCFS Queue.
The data:
Define a class named Customer with four private attributes:
CustomerName: 15-character c-string which is the name of the customer or regular string
ArrivalTime: integer, which is the arrival time of the customer
ServiceTime: integer, which is the time point that the customer starts to be serviced
FinishTime: integer, which is the leaving time of the customer
And two public methods:
1. method setCustomer that takes 3 parameters: customer name as a character array or a string, arrival time as an integer, and service time
as an integer
2. method displayCustomer will display a customer name, arrival time, service time, and finish time.
3. and 2 constructors:
1. Default Constructor
2. Parameterized with 3 parameters: customer name as a character array or a string, arrival time as an integer, and service time as
an integer
