Print Pyramid Pattern in C | Number, Star, Alphabet & Invert

The patterns of the pyramid will be covered in this article. We shall learn about numbers, stars, and C language alphabets here. A polygon structure has pyramid motifs. By joining a base that will be a polygon and all the lateral sides that are triangles, a pyramid is generated. The apex, which connects all of the bases, forms a triangle with the base and the apex. Learning patterns can help you become a more logical programmer.

And when firms ask these kinds of pattern questions in examinations, competitions, and interviews, they are quite significant. Beginners can learn the basics of loops and spaces by using questions of this type. We will learn how to create pyramid patterns in this tutorial. Simple concepts are all that are required for patterns.

With the use of examples, we will go over how to design various patterns in this article.

Introduction of Number Patterns in C language

The ability to create logic while using the Flow Control Statements is increased by practising Pattern exercises, which are frequently advised by programmers as well as in publications. Additionally, it improves logical reasoning skills. This article will provide beginners and intermediate programmers with a collection of number patterns to practice.

C Program for Print Pyramid Pattern of Numbers

#include <stdio.h>

int main()
{
	int i, j;
	int k = 1;
	for (i = 0; i <= 4; i++)
	{
		printf("\n");
		for (j = 0; j < i; j++)
		{
			printf("%d\t", k);
			k++;
		}
	}

	return (0);
}

Output

Pyramid Pattern of Numbers Explanation

In this code, as we know, we have to print a triangle in the form of numbers 1 to 10. Initially, we have taken k=1, i = rows, j = column, and in this code, we will run two loops, one for each row and another one for the column, so the first loop says for(i = 0; i<=4;i++) the number of rows keeps on increasing one by one in further steps. Now in the second loop for(j = 0; j<i; j++), the number of columns will increase, and both the loops will keep on working till 10.

C Program to Print Triangle Pattern

#include <stdio.h>

int main()
{
	{
		int i, j;
		for (i = 1; i <= 4; i++)
		{
			for (j = 1; j <= i; j++)
			{
				printf("%d", i);
			}

			printf("\n");
		}

		return (0);
	}
}

Triangle Pattern Explanation

In this code, as we know, we have to print a triangle in the form of numbers 1 to 4 but this time in a row the numbers are the same. we know that i = rows, j = column, and in this code, we will run two loops, one for each row and another one for the column, so the first loop says for(i = 1; i <=4;i++) the number of rows keeps on increasing but following the same number, as we are not increasing the digit. Now in the second loop for(j = 1; j<=i; j++), the number of columns will increase.

C Program to Print This Square Pattern

#include <stdio.h>

int main()
{
	{
		int i, j;

		for (i = 1; i <= 4; i++)
		{
			for (j = 1; j <= 4; j++)

				printf("%d", i);

			printf("\n");
		}

		return (0);
	}
}

Output

1 1 1 1

2 2 2 2

3 3 3 3

4 4 4 4

Square Pattern Explanation

In this code, we want to print a square numeric pattern. Two loops will run here, as you can see in the first loop it’s written for(i=1;i<=4;i++)means each row will carry the same number but it is according to the second loop for(j=1;j<=4;j++) the number will increase.
Introduction of Star pattern in C

In the C programming language, you only need to perform two or three loops to create a star pattern. How many loops you use will depend on the pattern you need to make. One for a row and one for a column are required as the minimal number for a pattern. The first loop is referred to as an outer loop and displays the rows, while the second loop is referred to as an inner loop and displays the columns.

C Program to Print Star Triangle

#include <stdio.h>

int main()
{
	{
		int i, j, k;

		for (i = 1; i <= 5; i++)

		{

			for (j = 4; j >= i; j--)

			{

				printf(" ");
			}

			for (k = 1; k <= (2 i - 1); k++)

			{

				printf(”“);
			}

			printf("\n");
		}

		return (0);
	}
}

Star Triangle Explanation

In this code, we will run an outer loop from 1 to i to iterate through the rows. The loop should be formatted as for(i=1; i<=5; i++) Run an inner loop from I to rows in order to iterate through the columns. The loop should be formatted as for(j=4; j>=i; j--).

Run a second inner loop from 1 to 2 * i - 1 to print the star. The appropriate loop form is for(k=1; k<=(2*i-1); k++).*This loop print has a star inside. Move to the next line, or print a new line, after printing each column in a row.

C Program to Print Inverted Star Pattern

#include <stdio.h>

int main()
{
	{
		int i, j, k;

		for (i = 4; i >= 1; i--)

		{

			for (j = 4; j > i; j--)

			{

				printf(" ");
			}

			for (k = 1; k < (i *2); k++)

			{

				printf(””);
			}

			printf("\n");
		}

		return (0);
	}

Inverted Star Pattern Explanation

In this code, we will run an outer loop from 1 to i to iterate through the rows. The loop should be formatted as for(i=4;i>=1;i--). Run an inner loop from I to rows in order to iterate through the columns. The loop should be formatted as for(j=4; j>=i; j--).

Run a second inner loop from 1 to 2 * i - 1 to print the star. The appropriate loop form is for(k=1; k<(i2); k++).*This loop print has a star inside. Move to the next line, or print a new line, after printing each column in a row.

Star Triangle Explanation

In the above code, the two for loops are used as you can see. here we used i, j, and k as required. on the execution of both loops, stars will be printed. On the different lines. Move to the next line, or print a new line, after printing each column in a row.

C Program to Print Inverted Star Triangle

#include <stdio.h>

Inverted Star Triangle Explanation

In this code, we will run an outer loop from 1 to i to iterate through the rows. The loop should be formatted as for(i=5; i>=1; i- - ). Run an inner loop from I to rows in order to iterate through the columns. The loop should be formatted as for(j=1; j<=i; j++). This loop print has a star inside. Move to the next line, or print a new line, after printing each column in a row.
Introduction of Alphabet Pattern in C

Any alphabet pattern can be printed in C. Here, I'll show how to print the alphabet pattern in C with an explanation.

A set of upper or lowercase alphabets which together form a pattern or geometric shape, such as a square, pyramid, triangle, etc., is known as an alphabet pattern. Controlled loops that are nested are being used to produce these patterns.

C Program to Print Alphabet Pattern

#include <stdio.h>

int main()
{
	{
		int i, j;

		for (i = 1; i <= 6; i++)

		{

			for (j = 1; j <= i; j++)

			{

				printf("%c", 'A' + j - 1);
			}

			printf("\n");
		}

		return (0);
	}
}

Output

A

ABCD

ABCDE

Alphabet Pattern Explanation

In this code, we will run an outer loop from 1 to i to iterate through the rows. The loop should be formatted as for(i=1;i<=6;i++). Run an inner loop from I to rows in order to iterate through the columns. The loop should be formatted as for(j=1;j<=i;j++). And using this structure,'A' + j-1 Move to the next line, or print a new line, after printing each column in a row.

Conclusion

Pyramid patterns come in different types. The most crucial thing is to understand the structure of numbers and whitespaces. Once you understand the pattern, writing code in C or any other programming language will come naturally to you.
