*    *
 ****

Ans.

/*c program for star square design*/
#include<stdio.h>
int main()
{
 int cols,rows,r,c,sp;
 printf("Enter no. of columns: ");
 scanf("%d", &cols);
 printf("Enter no. of rows: ");
 scanf("%d", &rows);
 for(r=1; r<=cols; r++)
 {
  if(r==1 || r==cols)
      printf(" ");
  else
      printf("*");
 }
 printf("\n");
 for(c=1; c<=rows-2; c++)
 {
   printf("*");
   for(sp=1; sp<=cols-2; sp++)
       printf(" ");
   printf("*\n");
 }
 for(r=1; r<=cols; r++)
 {
   if(r==1 || r==cols)
       printf(" ");
   else
       printf("*");
 }
 getch();
 return 0;
}

The output of above program would be:
