如何用C语言在表中编写2D数组

Question

I have a project which is like this: its a game to between two players in a randomly generated square table from 4 to 10. players roll 3 dices. the first dice and second are used for the location and the 3rd dice is the value which will be put into a table made of '-' and '*'. the table looks like a checkers board. now i want to insert this number created randomly into the table. I don't know how. in other words, how do you insert an array into a table that was made before? as you can see the code is below, since this is a shared project with a friend i don't have the table ready but i'll post it as soon as possible. this function is supposed to find the randomize the location and the value. also the size of the array is randomized in another function. it's a mess .

#include <stdio.h>
int rolldice(int p)
{
   int x,y,z;
   int ar[p][p];
   x=1+rand%6;
   y=1+rand%6;
   if(z==0){
      z=1+rand%6;
      ar[x][y]=z;
   }
   else {
      printf("other player roll please");
   }
   return z;
}
int table(int n);
int main(){

int size,t;
srand(time (NULL));
size = 4 + ( rand() % 7);
int array[size][size];
table(size);
rolldice(size)
}
int table(int n){
int k,a,m;
int ar[n][n];
for (m=1;m<=n;m++){
printf(" __");
}
for (k=1;k<=n;k++){
    printf("\n");   
    for (a=1;a<=n;a++){
        printf("|__");
        printf("%c",ar[k][a]);
        if(a==n){
            printf("|");
        }
    }
}
}

Here is the code you wanted to see.

#include <stdlib.h>

#define SIZE 4

int ar[SIZE][SIZE]=
{
    {1, 0, 3, 8},
    {4, 0, 5, 0},
    {9, 0, 2, 1},
    {1, 0, 6, 2}
};

int main() {
    printTable();

    return 0;
}
printTable(){
    int i;
    int j;

    for(i = 0; i<SIZE+1;i++){
        for(j=0; j<SIZE+1;j++){
            if(i==0 || j==0 || j==SIZE || i==SIZE)
                printf(" * ");
            else if(j==SIZE-1)
                printf("%d",ar[i][j]);
            else
                printf("%d - ",ar[i][j]);
        }
        printf("\n");
    }
}

So as you can see this prints 2D array as a table, its also possible to pass that array as a parameter to function printTable() .
