#include <iostream>
using namespace std;

const double GramsPerOunce = 28.35; 
const double GramsPerTroyOunces = 31.1; 
const double CurrentValuePerTroyOunceGold = 1744.50;
const double FullKarat = 24;

int main ()
{
  unsigned int Weight;
  double Grams, TroyOunces, FullValue, Karats, AdjustedValue;

  cout << "Please enter your weight of Gold in ounces => ";
  cin >> Weight;
  cout << endl << endl;

  cout << "Please enter the Quality of gold in Karats => ";
  cin >> Karats;
  cout << endl << endl;


  Grams = Weight * GramsPerOunce;	 

  TroyOunces = Grams / GramsPerTroyOunces;

  FullValue = TroyOunces * CurrentValuePerTroyOunceGold;

  AdjustedValue = FullValue * Karats / FullKarat;

		
  cout << "Your "<< Weight << " ounces of Gold with a Karat Quality of " << Karats << " is $" << AdjustedValue << endl  << endl;
	
  system("pause");
  return(0);
}


I need to modify it's code to include three functions:
1. Get the weight
2. Calculate the value
3. Print the results

What I have so far is... probably not even right.

I'm especially confused about what to even put in main, which is why it's pretty much empty. Note I haven't learned arrays or any of that awesomeness. It's bare bones C++ here.

Any direction would be highly appreciated.
