Program to print solid and hollow square patterns in C

CServer Side ProgrammingProgramming

Program Description

In geometry, a square is a regular quadrilateral, which means that it has four equal sides and four equal angles.

Solid and Hollow Square will appear as shown below

Algorithm

For Solid Square −

Accept the Number of Rows from the user to draw the Solid Square
For each Row, Print * for each Column to draw the Solid Square

For Hollow Square −

Accept the Number of Rows from the user to draw the Hollow Square
For the First and Last Row, Print * for each Column
For the Remaining Rows, Print * for the first and Last Column.

Example

/* Program to print hollow and Solid Square pattern */
#include <stdio.h>
int main(){
   int r, c, rows; //Hollow Rhombus
   int r1,c1, rows1; //Solid Rhombus
   clrscr();
   /* Hollow Square */
   printf("Enter the Number of rows for Hollow Square: ");
   scanf("%d", &rows);
   printf("\n");
   for (r=1; r<=rows; r++){
      if (r==1 || r==rows){
         for (c=1; c<=rows; c++){
            printf("*");
         }
      }
      else{
         for (c=1; c<=rows; c++){
            if (c==1 || c==rows){
               printf("*");
            }
            else{
               printf(" ");
            }
         }
      }
      printf("\n");
   }
   printf("\n");
   /* Solid Square */
   printf("Enter the Number of rows for Solid Square: ");
   scanf("%d", &rows1);
   printf("\n");
   for (r1=1; r1<=rows1; r1++){
      for (c1=1; c1<=rows1; c1++){
         printf("*");
      }
      printf("\n");
   }
   getch();
   return 0;
}
