Pyramid program right half

The right half pyramid pattern program is frequently queried in interviews. Explore its logic with interviewspreparation.com to enhance your understanding.

Why Right half pyramid program?

This question is often posed to programming beginners seeking internships. The right half pyramid pattern, requiring basic looping skills, is a common choice. It assesses your approach to achieving the desired pattern. there are lost of pyramid pattern program available on internet.

Understand right half pyramid program

If you’re a beginner and haven’t yet created a star pattern program, I highly recommend checking out our Star pattern program post on interviewpreparation.com. There, the process of creating rows and columns in your program is thoroughly explained.

Whenever an interviewer asks you to create a pattern program, it’s crucial to first determine the number of rows and columns required. In this case, we’re aiming to create a 4 by 4 right half pyramid, as mentioned in the image above. This means we’ll have 4 rows and 4 columns.

Note that when writing the code, the length parameter corresponds to the count of rows and columns.

Check that our first row contains only one star, and as each row continues to increase, the number of columns also increases. In other words, each row has a number of columns equal to its row count.

In the code, the outer loop represents each row, and within each row, the nested loop iterates up to the row count. When the row count reaches its limit, the program executes, completing the right half pyramid pattern. Let’s delve into the code to gain a better understanding.

Logic behind right half pyramid program

I assume you’ve already visited our Star pattern program at interviewspreparation.com. That program will help you understand the columns and rows of pattern programs. Therefore, I’ll directly dive into the right half pyramid pattern program.

Step 1 :

The first step is to display a 4 by 4 grid of rows and columns, with each cell containing the * symbol.

for (int row = 0; row < 4; row++)
{
    for (int column = 0; column < 4; column++)
    {
        Console.Write(" * ");
    } 

    Console.WriteLine();
}

Output :

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

Step 2 :

Now that you have rows and columns, consider what you would need to do to ensure that each row has only its size amount of * symbols. Your answer would be to stop the nested loop when it reaches the current row’s size amount, am I correct?

When you wrote your nested loop, you stopped it at the length of 4, correct? This gave you a 4 by 4 grid of rows and columns. Now, to complete the right half pyramid program, you need to stop it at your current row count. Let’s achieve this in the code.

for (int row = 0; row < 4; row++)
{
    for (int column = 0; column <= row; column++)
    {
        Console.Write(" * ");
    } 

    Console.WriteLine();
}

Output:

*
*  *
*  *  *
*  *  *  *

I hope you’ve grasped the concept of the right half pyramid pattern program. It’s quite straightforward, isn’t it?

Summarizing the right half pyramid pattern program

If you’re a regular visitor to interviewspreparation.com, completing this pattern program should be relatively easy for you. However, for those who are new to it, let’s summarize. The first step is to display a grid of the given size. Then, within the nested loop for columns, stop at the current row count and execute your program. You’ll find that the right half pyramid program is completed successfully.
