Write a C++ program to calculate the total expenses if quantity and price per item are input by the user and discount of 20% is offered if the expense is more than 10000.  

Program Code:

#include<iostream>

using namespace std;

int main()

{

int total_expenses, quantity, price, discount;

cout<<"Enter total quantity to be purchased  :";

cin>>quantity;

cout<<endl;

cout<<"Enter price of total quantity purchased  :";

cin>>price;

cout<<endl;

total_expenses = quantity * price;

if(total_expenses>10000)

{

discount=(total_expenses*0.2);

total_expenses=total_expenses-discount;

}

cout<<"Total Expense is  Rs. "<<total_expenses;

return 0;

}

The program output is tested on www.jdoodle.com

Output:

Enter total quantity to be purchased : 10

Enter price of total quantity purchased : 15000

Total Expense is  Rs. 120000
