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

#include <iostream>

using namespace std;

void takeInput(int &spoolsOrdered, int &spoolsInStock, int &shippingAndHandlingCharges) {
do {
cout<<"Enter number of spools ordered: ";
cin>>spoolsOrdered;
} while(spoolsOrdered < 1);
do {
cout<<"Enter number of spools in stock: ";
cin>>spoolsInStock;
} while(spoolsInStock < 0);
do {
cout<<"Enter special shipping and haddling charges: ";
cin>>shippingAndHandlingCharges;
} while(shippingAndHandlingCharges < 0);
}

void displayInformation(int spoolsOrdered, int spoolsInStock, int shippingAndHandlingCharges=10) {
int spoolsReadyToShip = spoolsOrdered;
int spoolsOnBackOrder = 0;
if (spoolsOrdered > spoolsInStock) {
spoolsReadyToShip = spoolsInStock;
spoolsOnBackOrder = spoolsOrdered - spoolsInStock;
}
int totalSalesPrice = spoolsReadyToShip * 100;
int totalShippingAndHandlingCharges = shippingAndHandlingCharges * spoolsReadyToShip;
int totalPrice = totalSalesPrice + totalShippingAndHandlingCharges;
cout<<"Spools ready to ship: "<<spoolsReadyToShip<<endl;
cout<<"Spools on backorder: "<<spoolsOnBackOrder<<endl;
cout<<"Total sales price: $"<<totalSalesPrice<<endl;
cout<<"Total shipping and handling charges: $"<<totalShippingAndHandlingCharges<<endl;
cout<<"Total price: $"<<totalPrice<<endl;
}

int main()
{
int spoolsOrdered, spoolsInStock, shippingAndHandlingCharges;
takeInput(spoolsOrdered, spoolsInStock, shippingAndHandlingCharges);
shippingAndHandlingCharges+=10;
displayInformation(spoolsOrdered, spoolsInStock, shippingAndHandlingCharges);
return 0;
