Write a C++ program that asks for the number of units sold and computes the total cost of the purchase.

Object:

A software company sells a package that retails for $99. Quantity discounts are given according to the following table:

  • Quantity Discount :
  • 10-19 20%
  • 20-49 30%
  • 50-99 40%
  • 100 or more 50%

Write a program that asks for the number of units sold and computes the total cost of the purchase.
Input validation: Make sure the number of units is greater than 0. C++ Projects.

Code:

#include<iostream>
#include<conio.h>

using namespace std;
void main()
{
double cost, qunt;
cout<<“\n\t**************************************************************************************\n”;
cout<<“\t\t:S o f t w a r e c o m p a n y sells a p a c k a g e:\n”;
cout<<“\t**************************************************************************************\n\n”;

cout<<“Enter here how many unit sold : “;
cin>>qunt;
if(qunt >0 && qunt <10)
