The Assignment
Working with your partner, write a C++ program which reads in the number of items a user wants to buy (an integer) and then computes the final cost (a real number). Items cost $5 each but customers will receive a $10 discount (i.e. subtract $10 from their total) if their total bill is at least $50. You should compute the final cost in the variable cost.
Begin by creating a new C++ file called Discount.cpp in a C++ compiler. Next, copy and paste this starter code into the file:
#include <iostream>
using namespace std;
int main()
{
// declare a variable to store the total cost...
double cost = 0.0;
// declare a variable to contain the number of items (an int)...
// Receive the number of items from the user (no prompt)....
/* add an output statement with a descriptive message about how many items
were entered by the user... */
/* Calculate the total cost and store it in the variable "cost". You need to
make a decision here: Recall items cost $5 each with a $10 discount if the
total is at least $50... */
// output the final cost...
cout << "Final cost is $" << cost << endl;
// return "success" to the operating system (OS)...
return 0;
}
Modify the code to complete the assignment. When you have completed the assignment, demonstrate it for the instructor.
