//Purpose: Finish this program so taht it uses the following two functions:
//    ReadNums - a void function called in main that uses cin to read three
//       numbers that the user will type in, these three numbers will be 
//       In/Out parameters that main will then pass to the next function
//    CalcMax - an int single value returning function that will determine
//       the maximum of the three numbers.


#include <iostream>
using namespace std;

//Function declarations (prototypes) for ReadNums and CalcMax go here
void ReadNums(int& x, int& y, int& z);
int Calcmax(int max);

int main()
{
    int x=0;
    int y=0;
    int z=0;
    int max;

    //Read in the three numbers using the ReadNums function
    ReadNums(x, y, z);
    

    //Calculate the max using the CalcMax value returning function
    if (x > y && x > z)
	{
		cin >> max;
	}
	else if (y > x && y > z)
	{
		cin >> max;
	}
	else if (z > x && z > y)
	{
		cin >> max;
	}
    

    //Print the maximum
    cout << "The maximum value of the three numbers you entered is " << max << endl;

    return 0;
}

//ReadNums function definition goes here
//The function will prompt the user to enter three numbers, read the 
//numbers and then pass those three numbers back to main.
void ReadNums(int& x, int& y, int& z)
{
	cout << "Enter three numbers with a space in between each number and press Enter: ";
	cin >> x >> y >> z; 
}

//CalcMax function definition goes here
//It will return an int
