Question

Q1. Write program calculate the final price of a purchased item using values entered by the user

Hint: you are required to use formatting output for number, currency and percentage.

--------------------[Print Receipt] ------------

Enter the quantity: 6

Enter the unit price: $1.98

Subtotals: $10.14

Tax: $ 0.61 at 6%

Total: $10.75

------------------------------------------------

Q2. Write a program that prompts for and reads the users’ first name and last name, Job title, DOB (date of Birth), and the Email address (separately). Then create and print a random phone number of the form XXX-XXX-XXXX. Include the dashes in the output. Do not let the first three digits contain an 8 or 9 (but don’t be more restrictive than that), and make sure that the second set of three digits is not greater than 742. Hint: Think through the easiest way to construct the phone number. Each digit does not to be determined separately.

----------------------------[ User details] ---------------------

First name: Adam

Last Name: Hunter

Date of Birth: 20/02/1981

Email Address: [email protected]

Phone number: 235-653-3541

this is a software development question using c++ programing language

Answer 1

CODE :

//Q1. Write program calculate the final price of a purchased item using values entered by the user

#include<iostream>   //for using standard I/O operations
#include<iomanip>   //for set precision function
using namespace std;

int main(){
  
//   declaration of variable for taking inputs from the user
   int quantity;
   double price;
   cout<<"---------------------[Print Receipt]-------------------\n";
//   taking the quantity
   cout<<"Enter the quantity: ";
   cin>>quantity;
  
//   prompting for the quantity of the one unit
   cout<<"Enter the unit price: $";
   cin>>price;
  
//   calculating the subtotal
   double subtotal=quantity*price;
   cout<<"Subtotals: $"<<setprecision(4)<<subtotal<<endl;
  
//   calculating the tax at 6%
   double tax=subtotal*6/100;
   cout<<"Tax: $"<<setprecision(2)<<tax<<" at 6%"<<endl;
  
//   calculating the total price after paying the tax at 6%
   double total=subtotal+tax;
   cout<<"Total: $"<<setprecision(4)<<total;
}
