Question

Sonia uses noon website to buy various items. if the total cost of the ordered items, at one time is 1000 AED or more then the shipping is free: otherwise the shipping will cost 10 AED/ item. write a C++ program that prompts Sonia to enter the number of items ordered and the price of each one of them. the program will then output the total billing amount, your program must use a for loop.

Answer 1

// C++ program to compute the total billing amount for the ordered items
#include <iostream>

using namespace std;

int main()
{
// initialize total cost to 0
double total_cost = 0, cost;
int num_items;

// input the number of items ordered
cout<<"Sonia, enter the number of items ordered: ";
cin>>num_items;

// for loop to input cost for each item, adding it to total cost
for(int i=0;i<num_items;i++)
{
cout<<"Enter the cost of item-"<<(i+1)<<": ";
cin>>cost;
total_cost += cost;
}

// if number of items > 0 and total cost < 1000, add shipping cost of 10AED/item
if(num_items > 0 && total_cost < 1000)
total_cost += (10*num_items);

// display the total billing amount
cout<<"Total billing amount: "<<total_cost<<" AED"<<endl;

return 0;
}

//end of program

Output:
