How to connect a pair of number in 2d array?

I am new to c programming. My aim is to break out the loop and move the number to connect to each other. I am not sure why my code is not working, I tried many times but still no luck. I really need help...please...

Here's my code :

  #include <stdio.h>
  #include <stdlib.h>

  void gameboard(char box[9][9])
 {

 int x,y;

 for(x = 0; x < 9; x++)
 {
    for(y = 0; y  <9; y++)
    {
     box[x][y] ='_'; 

   }


 }

for(x = 0; x < 9; x++)
  {

    box[0][x]='#';
    box[x][8]='#';

    box[x][0]='#';
    box[8][x]='#';


        }

}

     void rnum(char box[9][9])
           {

     int x,r1,r2,r3,r4;
     char r='1';


     srand( (unsigned) time(NULL)); 

       for(x=0;x<8;x++)
        {

      r1 = 1 + rand()%7;
      r2 = 1 + rand()%7;
      r3 = 1 + rand()%7;
      r4 = 1 + rand()%7;

      box[r1][r2]= r + x;
      box[r3][r4]= r + x;
      } 

     }


     void playgame(char box[9][9])
     {
           int x, y, choice2,num;
           char input;

        do{

        printf("Please select a number (1-7) : ");
     scanf("%i",&num);

        if(num==0 ||num > 7)
        {

        printf("Invalid!\n");


        }
        else
        {

        printf("\nNumer %i is currently selected!\n", num);

        }
       }while(num==0 ||num > 7);

       printf("\n[1]Move\n[2]Sign out\n");
       printf("\nEnter choice: \n");
       scanf("%d", &choice2);


       switch(choice2)
       {
         case 1: 
            {
                printf("Press 'e' to go up\n");

            }

            {
                printf("Press 'd' to go right\n");

            }

            {
                printf("Press 's' to go left\n");

            }

            {
                printf("Press 'x' to go down\n");

            }

                fflush(stdin);
                scanf("%c", &input);
            break;

    case 2: printf("Bye!\n");
     }



     for(x=0; x<9; x++)

     for(y=0; y<9; y++)
     {     
       if(input == 'e')
         if(box[x][y]==num)
         {
          box[x-1][y]=num;
          }

        else if(input == 'd')
         if(box[x][y]==num)
         {
          box[x][y+1] =num;
          }


          else if(input == 's')
           if(box[x][y]== num)
           {
        box[x][y-1] = num;
        }

      else if(input == 'x')
         if(box[x][y]==num)
         {
          box[x+1][y] =num;
          }


       }


     }



         int main(void)
    {


       char box[9][9];
       char name[20];
       int x,y,choice,num;


       printf("************* WELCOME TO NUMBER CONNECT ! ******************\n\n");


printf("Please key in your name :");
scanf("%s", &name);

printf("***Good day %s, let's start the game...all the best!!!***\n\n", name);  



gameboard(box);

rnum(box);     

for(x = 0; x < 9; x++)
 {
  for(y = 0; y  < 9; y++)
    {
    printf(" %c ",box[x][y]);

     }

    printf("\n\n");
  }


playgame(box);

 for(x = 0; x < 9; x++)
 {
  for(y = 0; y  < 9; y++)
    {
    printf(" %c ",box[x][y]);

     }

    printf("\n\n");
  }


do {

   printf("[1] Game Start\n[2] Logout\n");
   printf("Enter your choice: ");
   scanf("%d", &choice);

   switch(choice)
   {

    case 1: printf("Please select a number (1-7) : ");
            scanf("%i",&num);
            break;

    case 2: printf("Bye!\n");
            break;
    }
}while(choice!=2);





 return 0;
 }
