Question

c++

A program that displays the status of an order.
a) Program uses 2 functions (in addition to main ()).
b) The first function asks the user for the data below and stores the input values in reference parameters.
c) Input data from user: # of spools ordered, # of spools in stock, any special shipping & handling charges over and above the $10 rate.
d) The second function receives as arguments any values needed to compute and display the following information:
e) # of spools ready to ship from current stock, # of ordered spools on backorder (if ordered > in stock),
f) Total sales price of portion ready to ship (# of spools ready to ship X $100),
g) Total shipping and handling charges on the portion ready to ship, Total of the order ready to ship.
h) Shipping & handling parameter in 2nd function should have a default argument of $10.00.
I) Input validation: Do not accept numbers < 1 for spools ordered,
J) Input validation: Do not accept numbers < 0 for spools in stock or for shipping & handling charges.

Answer 1

Code:

#include<iostream>
using namespace std;
void fun1(int &spools_ordered, int &spools_stock, int &special_charges)//function 1
{
   while(1)
   {
       cout << "# of spools ordered: ";cin>>spools_ordered;
       if(spools_ordered < 1)//input validation
       {
           cout << "Enter proper input" <<endl;
       }
       else break;
   }
   while(1)
   {
       cout << "# of spools in stock: ";cin>>spools_stock;
       if( spools_stock < 0)//input validation
       {
           cout << "Enter proper input" <<endl;
       }
       else break;
   }
   while(1)
   {
       cout << "special shipping & handling charges over and above the $10 rate: ";cin>>special_charges;
       if( special_charges < 0)//input validation
       {
           cout << "Enter proper input" <<endl;
       }
       else break;
   }
}
void fun2(int &spools_stock, int &spools_ordered, int &spools_ready, int &spools_backorder, int &sales_ready, int &total_ready, int &total_shipping, int shipping_charges=10)//function2 with default argument
{
   spools_ready = spools_stock;//since no of spools ready to be shipped are those which are in the stock
   spools_backorder = (spools_ordered > spools_stock ? spools_ordered - spools_stock : 0);//if there is enough stock, backdoor is 0 otherwise, it is the difference of spools ordered to those in stock
   sales_ready = spools_ready * 100;//sales is spools * 100
   total_shipping = spools_ready * shipping_charges;//product of no of spools and their shipping charges
   total_ready = sales_ready + total_shipping;//total is sales + shipping for all the spools
}
int main()
{
   int spools_ordered, spools_stock, special_charges, spools_ready, spools_backorder, sales_ready, shipping_charges, total_ready, total_shipping;
   fun1(spools_ordered, spools_stock, special_charges);
   fun2(spools_stock, spools_ordered, spools_ready, spools_backorder, sales_ready, total_ready, total_shipping, special_charges);
   cout << "# of spools ordered: " << spools_ordered << endl;
   cout << "# of spools in stock: " << spools_stock << endl;
   cout << "# of spools ready to ship from current stock: " << spools_ready << endl;
   cout << "# of ordered spools on backorder: " << spools_backorder << endl;
   cout << "Total sales price of portion ready to ship: " << sales_ready << endl;
   cout << "Total shipping and handling charges on the portion ready to ship: " << total_shipping << endl;
   cout << "Total of the order ready to ship: " << total_ready << endl;
   return 0;
}

Output:
