Thread: How do i get this program to print random numbers?

okay, so this is the program so far, it can print one number that I set it to. how can I edit this so it will print a random number which will be printed on the front of the two squares??

Code:

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#define ROW 9
#define COL 9
 
char image[2][ROW][COL];
//       COL
//     +----+
//     |    |    ROW
//     |    |
//     +----+
//
// 5x5 X and O images
char shapes[2][5][6] = { { "*   *"
                         , " * * "
                         , "  *  "
                         , " * * "
                         , "*   *" }
                       , { " *** "
                         , "*   *"
                         , "*   *"
                         , "*   *"
                         , " *** " }
                       };
void rectange()
{
    for(int k = 0; k < 2; k++)
    for(int r = 0; r < ROW; r++)
        for(int c = 0; c < COL; c++)
        {
            image[k][r][c] = ' ';
            int top    = (r == 0);
            int bottom = (r == ROW - 1);
            int left   = (c == 0);
            int right  = (c == COL - 1);
            // corner
            if ((top || bottom) && (left || right))
                image[k][r][c] = '+';
            else
            // top or bottom
            if (top || bottom) image[k][r][c] = '-';
            else
            // left or right
            if (left || right) image[k][r][c] = '|';
        }
}
void overlay_X_or_O()
{
    for(int k = 0; k < 2; k++)
    {
        int shape = rand() % 2;
        for(int r = 0; r < 5; r++)
            for(int c = 0; c < 5; c++)
                image[k][r + 2][c + 2] = shapes[shape][r][c];
    }
}
int main()
{
    srand(time(NULL)); // initialise random number generator
    rectange(); // initialise the image with a rectange
    overlay_X_or_O(); // overlay image of X or O on top
    // print the image
    char roll_num = '2,3';
    image[0][4][4] = roll_num;
    // print the image
    for(int r = 0; r < ROW; r++)
    {
        for(int k = 0; k < 2; k++)
        {
            for(int c = 0; c < COL; c++)
                printf("%c", image[k][r][c]);
            printf("  ");
        }
        printf("\n");
    }
    return 0;
