Answer to Question #261512 in C++ for saliha

Question

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

would save if they purchased packages B or C, and how much money Package B customers would save if

they purchased Package A or C. If there are no savings for a particular package, your program shall print

an appropriate message.

Answer 1

Part A: 
#include <iostream>


using namespace std;


int main() {
	float GBs;
	char package;
	float totalAmountDue=0;
	//ask how many GBs the customer has used in the month and which package the customer has subscribed for. 
	cout<<"How many GBs the customer has used?: ";
	cin>>GBs;
	cout<<"Which package the customer has subscribed for (A,B or C)?: ";
	cin>>package;
	//Package A: For Rs. 100 per month, 1 GB data is provided. Additional data can be purchased for Rs. 20 per 100 MB.
	if(package=='a' || package=='A'){
		totalAmountDue=100.0;
		if(GBs>1){
			totalAmountDue+=((GBs-1.0))*200;
		}
	}
	//calculates a customer’s monthly bill.
	//Package B: For Rs. 200 per month, 2.5 GB data is provided. 
	//Additional data can be purchased for Rs. 10 per 100 MB.
	if(package=='b' || package=='B'){
		totalAmountDue=200.0;
		if(GBs>2.5){
			totalAmountDue+=((GBs-2.5))*100;	
		}
	}
	//Package C: For Rs. 1000 per month, unlimited access is provided.
	if(package=='c' || package=='C'){
		totalAmountDue=1000.0;
	}
	//display the total amount due.
	cout<<"\nThe total amount due: "<<totalAmountDue<<"\n\n";


	cin>>GBs;
	return 0;

	//calculates a customer’s monthly bill.
	//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.
	if(package=='c' || package=='C'){
