There are many pattern programs are written by programmers for practice purposes. The pyramid star pattern in C is one of them. In this post, we will display half pyramid star pattern, inverted half pyramid star pattern, full pyramid star pattern, full pyramid star pattern at the center of the screen, and inverted full pyramid star pattern.

1. The Half pyramid star pattern

*
* *
* * *
* * * *
* * * * *

Below code display Half pyramid star pattern,

#include<stdio.h>
int main()
{

  // outer loop represents row
  for(int i=1;i<=5;i++)
  {
   
    // inner loop represents column
    for(int j=1;j<=i;j++)
    {
      printf("* "); // star
    }

    printf("\n"); // new line
  }

  return 0;
}

The previous program uses the increment operator to display the Half pyramid star pattern in C. But we can also use the decrement operator.

Half pyramid star pattern using both increment and decrement operators,

Here we will use the decrement operator for the outer loop and the increment operator for the inner loop to print the above print.

#include<stdio.h>
int main()
{
  // outer for loop with decrement operator
  for(int i=5; i>=1; i--)
  {
    // inner for loop with increment operator
    for(int j=i; j<=5; j++)
    {
      printf("* "); // star
    }

    printf("\n"); // new line
  }

  return 0;
}

Now, we will use the increment operator for the outer loop and decrement operator for the inner loop to print the same (above) pattern.

#include<stdio.h>
int main()
{
  // outer for loop with increment operator
  for(int i=1; i<=5; i++)
  {
    // inner for loop with decrement operator
    for(int j=i; j>=1; j--)
    {
      printf("* "); // star
    }

    printf("\n"); // new line
  }

  return 0;
}

2. The Inverted half pyramid star pattern

* * * * *
* * * *
* * *
* *
*

The code for the Inverted half pyramid star pattern is,

#include<stdio.h>
int main()
{
  // outer for loop
  for(int i=5; i>=1; i--)
  {
    // inner for loop
    for(int j=i; j>=1; j--)
    {
      printf("* "); // star
    }

    printf("\n"); // new line
  }

  return 0;
}

3. Write a C program to display the below star pattern

    *
   **

The code for the above pattern is given below,

#include<stdio.h>
int main()
{
   int n;

   printf("Enter number of rows: ");
   scanf("%d",&n);

   for(int i=1; i<=n; i++)
   {
     for(int j=1; j <= n-i; j++)
     printf(" "); // space 
     for(int k=1; k <= i; k++)
     printf("*"); // star

     printf("\n"); // new line
   }

   return 0;
}

4. Write a C program to display the below star pattern

*****

  *** 
   ** 
    *

The code for the above pattern in C is,

#include<stdio.h>
int main()
{
  int n;

  printf("Enter number of rows: ");
  scanf("%d",&n);

  for(int i=1; i<=n; i++)
  {
    for(int j=1; j<=n; j++)
    {
      if(j < i)
      printf(" "); // space 
      else
      printf("*"); // star
    }
    printf("\n"); // new line
  }
  
  return 0;
}

Full Pyramid Star Pattern in C

5. Write a C program to print Full pyramid star pattern

    *
   *** 
  *****
 *******
*********

Full star pattern program in C is given below,

#include<stdio.h>
int main()
{
  int n;

  printf("Enter number of rows: ");
  scanf("%d",&n);

  for(int i=1; i<=n; i++)
  {
    for(int j=1; j <= n-i; j++)
    printf(" "); // space 

    for(int k=1; k <= (2*i-1); k++)
    printf("*"); // star

    printf("\n"); // new line
  }

  return 0;
}

There are many another ways to solve this problem,

#include<stdio.h>
int main()
{
  int n;

  printf("Enter number of rows: ");
  scanf("%d",&n);

  for(int i=1; i<=n; i++)
  {
    for(int j=1; j< 2*n; j++)
    {
        if(j<= n-i)
        printf(" "); // spaces
        
        else if(j < n+i)
        printf("*"); //stars

    }
    printf("\n"); //next line
  }
  return 0;
}

The same pattern also can be displayed using the recursion.

#include<stdio.h>
void fullPyramid (int r)
{
   int c, space;
   static int stars = -1;

   if (r <= 0) return;

   space = r - 1;
   stars += 2;

   for (c = 0; c < space; c++)
   printf(" "); // space
   
   for (c = 0; c < stars; c++)
   printf("*"); // star

   printf("\n");

   fullPyramid(--r);
}

int main ()
{
  int n;
  printf("Enter number of rows: ");
  scanf("%d",&n);
  fullPyramid(n);
  return 0;
}

6. Full pyramid star pattern at the center of the screen

                                       *
                                      ***
                                     *****
                                    *******
                                   *********

Generally, on a computer screen, we can print Maximum 80 characters horizontally. Here we will print the full pyramid for n lines.

#include<stdio.h>
int main()
{
   int n, c=80;

   printf("Enter number of rows: ");
   scanf("%d",&n);

   for(int i=1; i<=n; i++)
   {
     for(int j=1; j<=(c/2-i); j++)
     printf(" "); // space

     for(int k=1; k<=(2*i-1); k++)
     printf("*"); //star

     printf("\n"); //next line
   }

   return 0;
}
