A software company sells a package that re discounts are given according to the followi A software company sells a package that retails for $99. Quantity discoun according to the following table. Quantity Discount
GIVEN:
Write a program to compute the total cost of a purchase after applying discounts.
NOTE: As the programming language is not mentioned, we have executed it in C++.
PROGRAM:
#include <iostream>
using namespace std;
int main()
{
//Initialize the variables
float Initial_cost, discount, total_cost;
int unit;
//Get the number of units from user
cout<<"How many units were sold : ";
cin>>unit;
//When unit is zero, print that the units must be greater than 0
if (unit==0)
{
cout<<"Units sold must be greater than 0";
}
else
{
//cost of one unit is $99
//So, Initial cost= number of units * 99
Initial_cost= unit * 99;
//when number of units is between 10 and 19, discount is 20%
if (unit >= 10 && unit <=19 )
{
discount=0.20;
total_cost= Initial_cost - (Initial_cost * discount);
}
//when number of units is between 20 and 49, discount is 30%
else if (unit >= 20 && unit <=49 )
{
discount=0.30;
total_cost= Initial_cost - (Initial_cost * discount);
}
//when number of units is between 50 and 99, discount is 40%
else if (unit >= 50 && unit <=99 )
{
discount=0.40;
total_cost= Initial_cost - (Initial_cost * discount);
}
//when number of units is greater than and equal to 100, discount is 50%
else if (unit >= 100 )
{
discount=0.50;
total_cost= Initial_cost - (Initial_cost * discount);
}
cout<<"The total cost of the purchase is $"<<total_cost;
}
return 0;
}
