#include<iostream>

#include<iomanip>

using namespace std;

int main()

{

cout << "\n**************\n"

<< " Software Sales"

<< "\n**************\n\n";

int units;

double subtotal, total;

cout << "Enter number of units sold: ";

cout << setprecision(2) << fixed;

if(units > 0 && units < 10)

{

total = units * 99;

cout << "The total is: $" << total << "\n\n";

}

else

{

if(units >= 10 && units <= 19)

{

subtotal = (units * 99) * 0.20;

total = (units * 99) - subtotal;

cout << "The total is: $" << total << "\n\n";

}

else

{

if(units >= 20 && units <=49)

{

subtotal = (units * 99) * 0.30;

total = (units * 99) - subtotal;

cout << "The total is: $" << total << "\n\n";

}

else

{

if(units >= 50 && units <= 99)

{

subtotal = (units * 99) * 0.40;

total = (units * 99) - subtotal;

cout << "The total is: $" << total << "\n\n";

}

else

{

if(units >= 100)

{

subtotal = (units * 99) * 0.50;

total = (units * 99) - subtotal;

cout << "The total is: $" << total << "\n\n";

}

else

{

cout << "The number of units has to be greater than 0!! \n\n";

}

}

}

}

}

system("pause");

return 0;

}

if(books >= 4)

{

points = 60;

cout << "You have earned: " << points << " points \n\n";

}

else

{
