cout array one page at a time

[snakesolid]

i have an array of 20000 elements and i need to print out but it has to be done in
a clean matter filling one page and continue when the user wants
here is what i have so far it print out my array but it would just go for ever

void showarray(const int array[], int size)
{
	for (int count = 0; count < size; count++)
		cout << array[count] << "  ";
	cout << endl;
}

this what i ended up doing is not the most effecient but it kind of worsk

void showarray(const int array[], int size)
{
	int check = 0;
	int continu;
	for (int count = 0; count < size; count++)
	{
		cout << array[count] << "  ";
		cout << endl;
		++check;
		if (check == 150)
		{
			cout << "**************************PRESS Any number to continue***********************" << endl;
			cin >> continu;
			if (cin.fail())
			{
				cout << "What the.... " << endl;
				cin.clear();
				cin.ignore(2000, '\n');
			}
			check = 1;
			continue;
		}
	}
}

Rather than printing a fixed number of spaces between each element, a neater result can be achieved by specifying the field width.

#include <iostream>
#include <iomanip>


void showarray(const int array[], int size)
{

    for (int count = 0; count < size; count++)
    {
        std::cout << std::setw(10) << array[count];   // print with a width of 10 characters

        if ((count+1)%5 == 0)                         // start a new line after each five elements
            std::cout << '\n';
    }

}

Example output:

I would like to do it like that:

void showarray(const int array[], int size)
{
	const int LINES_PER_PAGE = 20;
	const int ITEMS_PER_LINE = 10;

	int line = 0, col = 0;

	for (int item = 0; item < size; item++)
	{
		cout << array[item] << " ";
		col++;
		if (col >= ITEMS_PER_LINE)
		{
			col = 0;
			line++;
			cout << endl;
		}
		if (line > LINES_PER_PAGE)
		{
			line = 0;
			cout << "Hit any key to continue";
			getch();
		}
	} // for
} // showarray

You would need to include <conio.h>

filling one page and continue when the user wants

With so many items the user might have to press a key a few hundred times;
