...

1 Bytes = 8 bit

Memory is a long tap of Bytes.

Types of Array:

1. One Dimensional Array:

The array with only subscript that array is called as One Dimensional Array.

Example: int a[5]; ← subscript.

2. Two Dimensional Array:

The array with two subscript that array is called as Two Dimensional Array.

Example: int a[5][5]; ← subscript.

3. Multi-Dimensional Array:

The array with more than two subscript that array is called as Multi-Dimensional Array.

Example: Creating and Using Arrays in JavaScript

// One-dimensional array
let numbers = [1, 2, 3, 4, 5];
console.log(numbers[0]); // Output: 1

// Two-dimensional array
let matrix = [
  [1, 2, 3],
  [4, 5, 6],
  [7, 8, 9]
];
console.log(matrix[1][1]); // Output: 5

// Iterating through an array
for(let i = 0; i < numbers.length; i++) {
  console.log(numbers[i]);
}
