Answer to Question #284543 in C++ for Sara

Question

Write a C++ program that inputs the price of a shoe in a shop, then deducts the discount from the price of the shoe as follows:

20% discount if the price of the shoe is above or equal 40 BD.

10% discount if the price of the shoe is more than or equal 15 BD and less than 40 BD.

5% discount if the price of the shoe is more than or equal 7 BD and less than 15 BD.

0% discount if the price of the shoe is below 7 BD.

Then, your program should output:

The initial shoe price, the discount amount and the final shoe price after discount.

All numbers should be displayed with 2 decimal places.

Answer 1

#include <iostream>
#include <iomanip>
using namespace std;


int main() {
	double discount,priceShoe;




	cout<<"Enter the price of a shoe: ";
	cin>>priceShoe;
	//20% discount if the price of the shoe is above or equal 40 BD.
	if(priceShoe>=40){
		discount=priceShoe*0.2;
	}
	//10% discount if the price of the shoe is more than or equal 15 BD and less than 40 BD.
	else if(priceShoe>=15 && priceShoe<40){
		discount=priceShoe*0.1;
	}
	//5% discount if the price of the shoe is more than or equal 7 BD and less than 15 BD.
	else if(priceShoe>=7 && priceShoe<15){
		discount=priceShoe*0.05;
	}
	//0% discount if the price of the shoe is below 7 BD.
	else{
		discount=0;
	}
	double finalShoePrice=priceShoe-discount;
	cout<<fixed<<"\nThe price of a shoe: "<<setprecision(2)<<priceShoe<<"\n";
	cout<<"The discount of a shoe: "<<setprecision(2)<<discount<<"\n";
	cout<<"The final shoe price after discount: "<<setprecision(2)<<finalShoePrice<<"\n";


	cin>>discount;
	return 0;
}
