Question

Convert from Python to C++

how would this code be written in C++?

def calculate(price,quantity):
total=price*quantity
if(quantity<10):
discount=0
elif(quantity>=10 and quantity<=20):
discount=total*10/100
elif(quantity>20):
discount=total*20/100
#returning price after discount
return total-discount
  
quantity=float(input("Enter quantity: "))
price=float(input("Enter price: "))

print("Price after discount is ${0:.2f}".format(calculate(price,quantity)))

Answer 1

#include <iostream>

using namespace std;

double calculate(double price, int quantity){
    double total=price*quantity, discount;
    if(quantity<10)
        discount=0;
    else if(quantity>=10 and quantity<=20)
        discount=total*10/100;
    else if(quantity>20)
        discount=total*20/100;
    //returning price after discount
    return total-discount;
}

int main()
{
    int quantity;
    double price;
    
    cout<<"Enter quantity: ";
    cin>>quantity;
    
    cout<<"Enter price: ";
    cin>>price;
    
    cout<<"Price after discount is "<<calculate(price, quantity)<<endl;
    return 0;
