Question

Using loop statements, write a C++ program which takes the number of items that a shopper wants to buy, and then takes the price of each item, and at the end tells the shopper how much she must pay.

This is a sample of the output:

How many items do you have in your basket? 3
Enter the price in dollar? 10.25

Enter the price in dollar? 20.75

Enter the price in dollar? 67.5

You must pay 98.5 $ today.

The C++ program using while loop for the following problem is given below.with full code and output.

CODE

#include <iostream>
using namespace std;
//driver code
int main() {
int n; //initialize variable n to take no. of input
cout << "How many items do you have in your basket? ";
cin>>n;
//delcare array of size n and initialize amount with zero
//In loop we directly take input and add it to the amount
double amount=0;
double arr[n];
for(int i=0;i<n;i++){
cout<<"Enter the price in dollar?";
cin>>arr[i];
amount+=arr[i]; //adding item price to final amount
}
//here we display the resultant amount value
cout<<"You must pay "<<amount<<" $ today.";
