*Write a program that prompts the user to enter the price of an item and the discount offered as a percentage (on a scale of 0 to 100). The program should then calculate and display the new price.*

###### Solution

The discount amount can be easily calculated. You must multiply the before-discount price of the product by the discount value and then divide it by 100. The division is necessary since the user enters a value for the discount on a scale of 0 to 100. Be careful—the result is not the final price but only the discount amount.

The final after-discount price can be calculated by subtracting the discount amount that you calculated beforehand from the initial before-discount price.

## PHP

<?php echo "Enter the price of a product: "; $price_before_discount = trim(fgets(STDIN)); echo "Enter the discount offered (0 - 100): "; $discount = trim(fgets(STDIN)); $discount_amount = $price_before_discount * $discount / 100; $price_after_discount = $price_before_discount - $discount_amount; echo "The price after discount is: ", $price_after_discount; ?>

## Java

public static void main(String[] args) throws java.io.IOException { java.io.BufferedReader cin = new java.io. BufferedReader(new java.io.InputStreamReader(System.in)); int discount; double discount_amount, price_after_discount, price_before_discount; System.out.print("Enter the price of a product: "); price_before_discount = Double.parseDouble(cin.readLine()); System.out.print("Enter the discount offered (0 - 100): "); discount = Integer.parseInt(cin.readLine()); discount_amount = price_before_discount * discount / 100; price_after_discount = price_before_discount - discount_amount; System.out.println("The price after discount is: " + price_after_discount); }

## C++

#include <iostream> using namespace std; int main() { int discount; double discount_amount, price_after_discount, price_before_discount; cout << "Enter the price of a product: "; cin >> price_before_discount; cout << "Enter the discount offered (0 - 100): "; cin >> discount; discount_amount = price_before_discount * discount / 100; price_after_discount = price_before_discount - discount_amount; cout << "The price after discount is: " << price_after_discount; return 0; }

## C#

static void Main() { int discount; double discount_amount, price_after_discount, price_before_discount; Console.Write("Enter the price of a product: "); price_before_discount = Double.Parse(Console.ReadLine()); Console.Write("Enter the discount offered (0 - 100): "); discount = Int32.Parse(Console.ReadLine()); discount_amount = price_before_discount * discount / 100; price_after_discount = price_before_discount - discount_amount; Console.Write("The price after discount is: " + price_after_discount); Console.ReadKey(); }

## Visual Basic

Sub Main() Dim discount As Integer Dim discount_amount, price_after_discount, price_before_discount As Double Console.Write("Enter the price of a product: ") price_before_discount = Console.ReadLine() Console.Write("Enter the discount offered (0 - 100): ") discount = Console.ReadLine() discount_amount = price_before_discount * discount / 100 price_after_discount = price_before_discount - discount_amount Console.Write("The price after discount is: " & price_after_discount) Console.ReadKey() End Sub

## Python

price_before_discount = float(input("Enter the price of a product: ")) discount = int(input("Enter the discount offered (0 - 100): ")) discount_amount = price_before_discount * discount / 100 price_after_discount = price_before_discount - discount_amount print("The price after discount is:", price_after_discount)
