Mastering Arrays: A Dive into Declaration, Initialization, and Memory Allocation

Arrays form the backbone of data structures in programming, offering an efficient way to store and manage data. Here's what I learned recently about arrays and their fundamental concepts:

🔹 Memory Matters

• An integer (int) occupies 4 bytes (32 bits) in memory.
• A character (char) occupies just 1 byte.
• Arrays allocate memory sequentially, ensuring efficient data access using the Random Access Method (RAM).

🔹 Key Characteristics of Arrays

1. Homogeneity: Arrays are designed to store elements of a single data type. Mixing types will result in errors.
2. Static vs. Runtime Initialization:Static Initialization: Array size and elements are predefined.Runtime Initialization: Array size and elements can be set during program execution.

🔹 Understanding Array Addressing The memory address of an array element is computed as: Base Address + (Index × Size of Data Type) This ensures quick access to elements regardless of their position in the array.

Learning these concepts has deepened my understanding of how arrays operate and their importance in efficient programming.
