🔍 What is an Array?

Array ek linear data structure hai jo same type ke multiple values ko single variable name ke andar store karta hai.

🧠 Simple Words Mein:

Ek aisi box ki line jisme har box ek number rakh sakta hai — aur sabko ek hi naam se bulaya ja sakta hai (with index).

✅ Syntax:

datatype arrayName[size];

Example:

int marks[5];  // creates an array of size 5 to store integers

🧾 Array Memory Layout:

Suppose:

int arr[3] = {10, 20, 30};

Access like: arr[0], arr[1], arr[2]

📌 Features of Array:

• Fixed size (compile time defined)
• Same type ke elements (int, float, char...)
• Indexing starts from 0
