Create a class called Stack for storing integers. The data members are an integer array for storing

the integers and an integer for storing the top of stack (tos). Include member functions for initializing tos

to 0, pushing an element to the stack and for popping an element from the stack. The push() function

should check for “stack overflow” and pop() should check for “stack underflow”.

IFone, a cellular company, offersthe following three postpaid data packages to its customers.

(5+5 marks)

● Package A: For Rs. 100 per month, 1 GB data is provided. Additional data can be purchased for

Rs. 20 per 100 MB.

● Package B: For Rs. 200 per month, 2.5 GB data is provided. Additional data can be purchased

for Rs. 10 per 100 MB.

● Package C: For Rs. 1000 per month, unlimited access is provided.

Part A: Write a program that calculates a customer’s monthly bill. It should ask how many GBs the

customer has used in the month and which package the customer has subscribed for. It should then

display the total amount due.

Part-B: Modify the program in Part A so that it also displays how much money Package A customers

an appropriate message.

You are given a 9*9 grid as shown in the figure below. You can determine the color

of each square from the grid. The number of each square is also shown below. Write a C++ program for

this below given grid. The user is given two options to select from.

Part A: When the user selects 1st option, the user will enter number of square in this grid (any

number from 1-81). Your program will determine the color of the square.

Part B: When the user enters 2nd option, the user will enter two numbers from this grid. Your
