How to Create Pascal's Triangle in C using Arrays

Pascal's Triangle is a fascinating mathematical construct where each number is the sum of the two numbers directly above it. Creating a program to output Pascal's Triangle with user-defined rows can be a rewarding exercise in learning C programming. However, many beginners face challenges while trying to implement it correctly, especially when using arrays. If you've encountered problems while coding your Pascal's Triangle in C, you're not alone. Let's go through the common pitfalls and identify how to get your program up and running properly.

The Problem

You might have written a program only to find that it doesn't output Pascal's Triangle correctly. For instance, when you input 4 for the number of rows, your program might produce an incorrect sequence of numbers, which can be frustrating. Here’s a quick recap of what to expect from a correctly functioning Pascal’s Triangle for 4 rows:

Instead, your program might have printed something unexpected like:

This indicates there’s a problem with the way you've set up your arrays or logic. Let's dive into the solution now.

Debugging the Original Code

Initially, your code had a few issues to fix, including:

Declaration of zero-length arrays.

Wrong use of arrays to store results.

Improper logic in looping through and displaying Pascal’s Triangle.

Here's an improved version of your code and detailed steps explaining each part.

The Solution

Here’s the corrected code that accomplishes the task effectively:

Key Corrections Explained

Dynamic Arrays: Change from declaring static arrays with zero-length to dynamic arrays based on user input (int par[r], rar[r];). This allows you to allocate space according to the number of rows the user wants.

Correctly Printing: Adding spaces for formatting improves the visual representation of Pascal's Triangle, making it easier to follow the output structure.

Logic Adjustment: The conditions for setting values in rar[] are explicitly defined, ensuring that they follow the rules of Pascal's Triangle correctly.

Conclusion

By following this guide, you should be able to create a functioning Pascal's Triangle program in C without any hiccups. Remember, coding is all about trial and error, but with careful attention to detail, you can successfully achieve your desired outcome. Happy coding!
