Question

C++ Programming: Using Conditions

Hello, can anyone create a C++ program that will allow me to ask the user to supply the current total and the quantity of the hardware purchased. This program should calculate the grand total based on the number of units purchased as shown in the chart below:

Amount of Hardware	Discount Received
10-19	20%
20-49	30%
50-99	40%
100 or more	50%

Also, make sure to certify what happens when the user enter 0 or less items!

C++ Code :

#include <iostream>
using namespace std;
int main()
{
float total,quantity;
float discount=0,grandtotal;
cout<<"Enter current total : "; //entering total
cin>>total;
cout<<"Enter quantity : "; //entering grand total
cin>>quantity;
  
if(quantity<=0)
cout<<"Quantity cannot be negative or Zero "; //prints if the quantity is<=0
else
{
if(quantity>=10 && quantity<=19)
discount=20;
else if(quantity>=20 && quantity<=49)
discount=30;
else if(quantity>=50 && quantity<=99)
discount=40;
else if(quantity>=100)
discount=50;
  
grandtotal=total-((total*discount)/100); //calculates grand total based on the discount
cout<<"Grand total is :"<<grandtotal;
}
return 0;
}

8 12 14 #include <iostream> 2 using namespace std; 3 int main() 4-{ 5 float total, quantity; 6 float discount=0,grand total; 7 cout<<"Enter current total : "; //entering total cin>>total; 9 cout<<"Enter quantity : "; //entering grand total 10 cin>>quantity; 11 if(quantity<=0) 13 cout<<"Quantity cannot be negative or Zero "; //prints if the quantity is<=0 else 15 { 16 if(quantity>=10 && quantity<=19) 17 discount=20; 18 else if(quantity>=20 && quantity<=49) discount=30; 20 else if(quantity>=50 && quantity<=99) 21 discount=40; 22 else if(quantity>=100) 23 discount=50; 24 25 grandtotal=total-((total discount)/100); //calculates grand total based on the discount 26 cout<<"Grand total is :"<<grandtotal; 27 return 0; 29} 19 } 28 30

Output :

Enter current total : 100 Enter quantity : 10 Grand total is : 80
