Please find the code below:;

#include <iostream>
#include <stdlib.h>

using namespace std;
void displayArray(char array[][4]); //function to display array
bool gameFinish(char array[][4]); //check for game finish
int main()
{
   int array[4][4]; //array of size 4
   char arrayStar[4][4]; //array of size 4 for display *
   char digits[] = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9' }; //convert int to char
   int i=0,j=0;
   for(i=0;i<4;i++){
for(j=0;j<4;j++){
           array[i][j]=0;
           arrayStar[i][j]='*';   //initialize both array
       }
}
   int row=0,col=0; //rand row
   bool insert = true; //rand col
   for(i=1;i<=8;i++){ //for 1 to 8

       insert= true; //initialize variable

       }
       array[row][col] = i; //putting number
       insert = true; //again same step for second pair
