Putting an array in numerical order

[tylerb]

Hello Folks,

I need to write a program that takes an array and then displays it in reverse, displays only the even values, and displays the array in descending order. I figured out the first two, but I can't seem to quite figure out the last one.

Here's the whole code

  #include <iostream>
#include <iomanip>
using namespace std;

void getlist (int[], int &);
void putlist (const int [], int);
void reverse (const int [], int);
void EvenValues (const int[], int);
void GreaterThan (const int[], int);

const int MAXSIZE=25;

int main()
{
	int list [MAXSIZE];
	int num_items;
	
	getlist (list, num_items);
	putlist (list, num_items);
	reverse (list, num_items);
	EvenValues (list, num_items);
	GreaterThan (list, num_items);
}

void getlist (int list [], int &num_items)
{
	int i; 

    cout << "Please enter the number of array values ";
    cin >> num_items;
    
    for (i = 0; i < num_items; i++)
	  {
	  cout << "Enter the next array value " << endl;
	  cin >> list [i];
	  }
	
}

void putlist (const int list [], int num_items)
{
	cout << "Array Elements" << endl;

	for (int i = 0; i < num_items; i++)
		 cout <<i << "  " << list [i] << endl;
}

void reverse (const int list [], int num_items)
{
	cout << "Reverse Array Elements" << endl;
    
    for (int i = num_items-1; i >= 0; i--)
    	cout <<i << "  " << list [i] << endl;
	
}

void EvenValues (const int list [], int num_items)
{
	cout << "Even Elements in the Array" << endl;
	
	for (int i = 0; i< num_items; i++)
		if  (list [i]%2==0)
		cout <<i<< "  " <<list [i] << endl;
	
}

void GreaterThan (const int list [], int num_items)
{
	cout <<"Array Elements in Numerical Order" << endl;
	
	for (int i = 0; i < num_items; i++)
		if (list [i]>list [i+1])
		cout <<i<< "  " <<list [i] << endl;
}

Any help would be appreciated

Use sorting algorithm like http://www.cprogramming.com/tutorial/computersciencetheory/sorting2.html
