Solution in C (Clang 3.8.0) (judge verdict: Accepted)

#include<stdio.h>
int main()
{ int x,y,j,n,i;
  char a[1000][1000];
   scanf("%d%d",&x,&y);
   for(i=0;i<x;i++)
   scanf("%s",&a[i]);
   for(i=0;i<y+2;i++)
   printf("#");
   printf("\n");
    for(i=0;i<x;i++)
    {printf("#");
	  printf("%s",a[i]);
	  printf("#");
	  printf("\n");
	 } 
   for(i=0;i<y+2;i++)
   printf("#");
   printf("\n");
	   return 0;
