C program to print a symbol Hollow Parallelogram Pattern - My CS Tutorial

In this tutorial we will learn how to write a C program that print a symbol Hollow Parallelogram pattern.We will use any symbol to print this pattern.

C Program Code

#include<stdio.h>

#include<conio.h>

void main()

{

    int a,b,c=0,space=1,size;

    printf("\n Enter a number for size:\n ");

    scanf("%d",&size);

    printf("\n");

    for(a=size;a>=1;a--)

    {

     for(b=1;b<=a;b++)

     {

      printf("●");

     }

     if(a!=size)

     {

       for(c=1;c<=space;c++)

       {

         printf(" ");

       }

        space+=2;

     }

     for(b=a;b>=1;b--)

     {

      if(b!=size)

      printf("●");

     }

     

     printf("\n");

    }

   //Reverse printing

    space-=4;

    for(a=2;a<=size;a++)

    {

     for(b=1;b<=a;b++)

     {

      printf("●");

     }

     if(a!=size)

     {

       for(c=1;c<=space;c++)

       {

         printf(" ");

       }

        space-=2;

     }

     for(b=a;b>=1;b--)

     {

      if(b!=size)

      printf("●");

     }

     printf("\n");

    }

    getch();

}

OUTPUT:

We can see in this output it is a symbol Hollow Parallelogram pattern.
