Hollow Pyramid Star Pattern

For the pyramid at the first line it will print one star, and at the last line it will print n number of stars. For other lines it will print exactly two stars at the end of the line, and there will be some blank spaces between these two stars.

  •  Program:

#include<stdio.h>

void main()
{
    int a,b,c,d,e;
    printf("Enter the number of rows: ");
    scanf("%d",&a);
    b=a;
    for(c=1;c<=a;c++)
    {
        for(d=1;d<=b-1;d++)
        {
            printf(" ");
        }
        for(e=1;e<=2*c-1;e++)
        {
            if(e==1 || e==2*c-1 || c==a)
            {
                printf("*");
            }
            else
            {
                printf(" ");
            }
        }
        b--;
        printf("\n");
    }
}

  •  Output:

Enter the number of rows: 5

Full Diamond Star Pattern In C Programming Language 

For printing the star full diamond pattern, the number of line is taken as input. The pattern is divided into two part. In the first half, the number of the stars are increased and in the 2nd part, the number of stars are decreased. Two extra variables are taken here  to count the number of stars and the number of spaces for each line. for printing the number of line as input checking is done. If it is odd, then only the pattern can be printed else an error message is shown.

  •  Program:

#include<stdio.h>

int main()
{
    int a,b,c=1,d,e,f;

    printf("Enter the number of lines :");
    scanf("%d",&a);

    b=a/2+1;
    //printing this pattern is possible if the number of lines is odd
    if(a%2!=0)
    {
        //printing the first half of the pattern where the number of stars 
        //are increasing
        for(d=1;d<=a/2+1;d++)
        {
            for(e=1;e<=b;e++)
            {
                printf(" ");
            }
            for(f=1;f<=c;f++)
            {
                printf("*");
            }
            printf("\n");
            b--;
            c+=2;
        }
        //printing the second half of the pattern where the number of stars 
        //are decreasing
        b=b+2;
        c=c-4;
        for(d=a/2+2;d<=a;d++)
        {
            for(e=1;e<=b;e++)
            {
                printf(" ");
            }
            for(f=1;f<=c;f++)
            {
                printf("*");
            }
            printf("\n");
            b++;
            c-=2;
        }
    }
    //printing the error message if number of line is even
    else
    {
        printf("\nPlease give correct input(no. of line should be odd)");
    }
}

  •  Output:
