Answer 1

Answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

// main function

int main() {

//variable to store input

double price;

int totalNumber;

// variable to store total price

double total_price;

cout<<"Enter the price of an order:";

// read the price of an order

cin>>price;

cout<<"Enter the number of orders:";

// read the total number of orders

cin>>totalNumber;

// calculate total price of all orders

total_price=price*totalNumber;

cout<<"total price of all orders: "<<total_price<<endl;

return 0;

}

Explanation:

Declare three variables "price" of double type,"totalNumber" of int type And "total_price" of type double.Read the value of an order and number of orders. The calculate the total price by multiply "price" with "totalNumber" and assign it to variable "total_price". Print the total price.

Output:

Enter the price of an order:12.5                                                                                                                              

Enter the number of orders:3                                                                                                                                  

total price of all orders: 37.5
