how can i do a function?

[Maerle]

I would like to do a function just to output a gameboard instead of write the same code everytime when a change occurs.

#include <iostream>
#include <conio.h>
#include <cstdlib>
#include <time.h>

using namespace std;

int gameboard();

int main () {
    int gameboard[10][10];
    int row, col;
    srand(time(NULL));
    
    for (row = 0; row < 10; row++) {
        for (col = 0; col < 10; col++) {
            gameboard[row][col] = 0;
            cout << gameboard[row][col] << " ";
        }
        cout << endl;
    }
    
    gameboard[0][0] = 6;
    gameboard[9][9] = 9;
    
    for (row = 0; row < 10; row++) {
        for (col = 0; col < 10; col++)
            cout << gameboard[row][col];
        cout << endl;
    }
    
    getch();
    return 0;
}

Hi
have put drawgameboard as a function
and moved gameboard [10][10] as a global variable

also have initialixed gameboard in main function.

I notice you have srand so assume you will be using random numbers to change
the board. If you are I would put this in a while loop to update until finished

#include <iostream>
#include <conio.h>
#include <cstdlib>
#include <time.h>

using namespace std;

void	drawGameboard();

int gameboard[10][10];

int main () {
    
	for (int i=0;i<10;i++)
	{
		for (int j=0;j<10;j++)
		{
			gameboard[i][j] = 0;
		}
	}

    srand(time(NULL));
    
    drawGameboard();
    
    gameboard[0][0] = 6;
    gameboard[9][9] = 9;
    
	drawGameboard();
    
    getch();
    return 0;
}
void	drawGameboard()
{
	int row, col;

	for (row = 0; row < 10; row++) {
        for (col = 0; col < 10; col++) {
            
            cout << gameboard[row][col] << " ";
        }
        cout << endl;
    }
	cout << endl;
}

Hoped This helps

I don't mean to be rude, but this is covered in the tutorial, and its very basic. I HIGHLY suggest reading the tutorial from start to finish: http://cplusplus.com/doc/tutorial/
