30 Pattern Program In C

In this article, you will learn to create 30 different Pattern program in C. Steps to create patterns are explained with the code.

1. Square pattern in C

The simplest pattern you can draw using C is a square pattern. It has a shape of a square or rectangle.

*****

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

Follow these simple steps to create the square pattern in C:

Take the size of the square or take user input.
Create a nested loop where the external loop prints rows and the inner loop prints each star in the column.
Print the stars using the command printf("*").

#include <stdio.h>

int main() {
  // take a size
  // you can take user input
  int size = 5;
  // external loop
  for (int i = 0; i < size; i++) {
    // internal loop
    for (int j = 0; j < size; j++) {
      printf("*");
    }
    printf("\n");
  }
  return 0;
}

Output:

*****

2. Hollow Square pattern in C

hollow square is a variation of square pattern. It has a similar shape but is hollow inside.

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

Steps to create a hollow square pattern in C are as follows:

Start with the size of the square.
Create a nested loop. Here the inner loop is a bit complex.
If the row is first or last print only star.
If the row is not first or last then print star at first and last position of row and space at the middle position.
Create a new line at the end of each row.

#include <stdio.h>

int main() {
  // size of the square
  int size = 5;
  // external loop
  for (int i = 0; i < size; i++) {
    // innternal loop
    for (int j = 0; j < size; j++) {
      // in first and last row print only stars
      if (i == 0 || i == size - 1) {
        printf("*");
      }
      else {
        // at first and last position
        // of row print stars else print spaces
        if (j == 0 || j == size - 1) {
          printf("*");
        }
        else {
          printf(" ");
        }
      }
    }
    printf("\n");
  }
  return 0;
}

Output:

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

3. Right triangle pattern program in C

The right triangle star pattern in C is a right angle triangle that has its perpendicular line at the right side of the triangle.

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

You can see the pattern above. Before printing stars, we have to print spaces in a certain pattern to push stars to the right side of the triangle.

Follow the steps below to create the right triangle star pattern in C:

Start with creating an external loop with 2 inner loops, 1st to print spaces and 2nd to print stars.
In the 1st inner loop start printing spaces for the size minus row number.
In the 2nd inner loop start printing stars for the row number.
At the end of both inner loops print a new line.

#include <stdio.h>

int main() {
  // set size
  // or take user input
  int size = 5;

  for (int i = 0; i < size; i++) {
    // printing spaces before stars
    for (int j = 1; j < size-i; j++) {
      printf(" ");
    }
    // printing stars
    for (int k = 0; k <= i; k++) {
      printf("*");
    }
    printf("\n");
  }
  return 0;
}

Output:

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

4. Right Down Triangle

The right down triangle is another triangle pattern which is a water image of a right triangle.

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

You can see the pattern above. It is very much the same as the right triangle star pattern with just little modifications in the code. Here is the complete code for this.

#include <stdio.h>

int main() {
  // take size
  int size = 5;

  for (int i = 0; i < size; i++) {
    // printing spaces
    for (int j = 0; j < i; j++) {
      printf(" ");
    }
    // printing stars
    for (int j = size; j > i; j--) {
      printf("*");
    }
    printf("\n");
  }
  return 0;
}

Output:

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

5. Left triangle star pattern in C

The left triangle star pattern is a triangle with a perpendicular line at the left side of the triangle.

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

Follow the steps below to create the left triangle star pattern in C:

Take the size of the triangle.
Start with creating a nested loop where the inner loop prints the star a number of times as the row number.
At the end of each row print new line by print("\n").

#include <stdio.h>

int main() {
  // take size of triangle
  int size = 5;
  
  for (int i = 0; i < size; i++) {
    // printing star in a row
    for (int j = 0; j <= i; j++) {
      printf("*");
    }
    printf("\n");
  }
  return 0;
}

Output:

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

6. Left Down Triangle

The left down triangle is a variation of the left triangle star pattern. It is a water image of this pattern.

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

With just a little modification in code, you can reverse the order of printing stars and spaces and create this pattern. Here is the complete code for this.

#include <stdio.h>

int main() {
  // size of the triangle
  int size = 5;

  for (int i = 0; i < size; i++) {
    // printing stars
    for (int j = 0; j < size-i; j++) {
      printf("*");
    }
    printf("\n");
  }
  return 0;
}

Output:

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

7. Hollow triangle star pattern in C

The hollow triangle star pattern is a little complex structure of a triangle. It is a triangle with a hollow space in the middle.

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

You can see the pattern above. You have to manage the spaces and stars in a certain way to create this pattern.

Set the size of your triangle.
Use nested loops where the external loop handles rows and the internal loop handles each column of the row.
In the internal loop check if it's not the last row and is 1st and last position of the row then print star, else print space.
In the last row print only stars.

#include <stdio.h>

int main() {

  int size = 5;

  // creating hollow triangle
  for (int i = 1; i <= size; i++) {
    for (int j = 0; j < i; j++) {
      // operation of non-last row
      if (i != size) {
        // 1st or last position of row print star
        if (j == 0 || j == i-1) {
          printf("*");
        } else {
          printf(" ");
        }
      }
      // last row print only star
      else {
        printf("*");
      }
    }
    printf("\n");
  }
  return 0;
}

Output:

8. Pyramid star pattern in C

The pyramid pattern in C is a very famous pattern shape that looks like an equilateral triangle.

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

The complete step to create a pyramid star pattern in C is given below:

Take the size of the pyramid as input or a fixed number (here 5).
Create an external loop with 2 internal loops inside. 1st loop prints spaces and 2nd loop prints stars.
Print spaces for a number of times as size minus row number.
Print stars for 2 times as row number minus 1.
Break the line after each row.

#include <stdio.h>

int main() {
  int size = 5;

  // creating pyramid
  for (int i = 0; i < size; i++) {
    // print spaces before stars
    for (int j = 0; j < size-i-1; j++) {
      printf(" ");
    }
    // print stars
    for (int k = 0; k < 2*i+1; k++) {
      printf("*");
    }
    printf("\n");
  }
  return 0;
}

Output:

    *

9. Hollow pyramid pattern program in C

The hollow pyramid is a normal pyramid but with a hollow space in the middle.

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

You can see the pattern above. This is a bit complicated to create this pattern. Here are steps to follow:

Create a nested loop with 2 internal loops to print spaces and stars.
In the first loop print only spaces for a number of times as size minus row number.
The functioning of the second loop is quite complex. In this loop check if it is the first or the last row then only print stars. If it is another row then check if it is 1st and last position of the row then print star, else print space.
Break the line after 2nd internal loop.

#include <stdio.h>

int main() {
  // size of the pyramid
  int size = 5;
  for (int  i = 0; i < size; i++) {
    // print spaces
    for (int j = 0; j < size-i-1; j++) {
      printf(" ");
    }
    // print stars
    for (int k = 0; k < 2*i+1; k++) {
      if(k == 0 || k == 2*i || i == size-1) {
        printf("*");
      } else {
        printf(" ");
      }
    }
    printf("\n");
  }
  return 0;
}

Output:

    *
   * *
  *   *
 *     *

Here is the complete code to create a reverse pyramid pattern in C.

#include <stdio.h>

int main() {
  // size of the pyramid
  int size = 5;
  for (int i = 0; i < size; i++) {
    // print spaces
    for (int j = 0; j < i; j++) {
      printf(" ");
    }
    // print stars
    for (int k = 0; k < 2*(size-i)-1; k++) {
      printf("*");
    }
    printf("\n");
  }
  return 0;
