Lecture 29 – C Programming | Types of Arrays in C | 1D, 2D & Multidimensional Arrays | By Mukesh Sir

Описание: Welcome to Lecture 29 of our C Programming Course! 🎓

In this lecture, Mukesh Sir explains all types of arrays in C — from basic 1D arrays to 2D and multidimensional arrays.
This session builds a strong foundation for matrix operations, string handling, and advanced data structures.

If you want to understand arrays deeply, this lecture is extremely important!

✔ Topics Covered in Lecture 29:
🔹 1. Types of Arrays

• 1D Array
• 2D Array
• Multidimensional Array (Concept)

🔹 2. 1D Array (Revision + Deep Understanding)

• Declaration
• Initialization
• Traversing
• Memory representation
• Index & boundary concepts
• Dry runs

🔹 2D Array (Matrix Basics)

• Declaration of 2D array
• Memory layout (Row-major order)
• Input & output using loops
• Accessing elements using row/column index
• Representation of a matrix
• Common mistakes in 2D arrays

🔹 Multidimensional Arrays (Introduction)

• Syntax
• Where they are used?
• How memory is stored?

📘 Programs Covered in This Lecture:

✔ Store & print a 2D matrix
✔ Add two matrices
✔ Find sum of each row
✔ Find sum of each column
✔ Find maximum element in 2D array
✔ Count positive, negative & zero values in 2D array
✔ Display matrix in proper tabular format

🌟 Why This Lecture Is Important?

Understanding array types is essential for:
👉 Matrix programs
👉 Strings in C
👉 Searching & sorting
👉 File handling
👉 Data structures (Stack, Queue, Linked List → later)
👉 Competitive programming logic

This lecture prepares you for Array Programs Part 1 & Part 2, coming next.
