Type of Array?

 

🔹 1. One-Dimensional Array (1D Array)

• A linear list of elements.

• Example in Python:

  python
  arr = [10, 20, 30, 40]
  

---

🔹 2. Two-Dimensional Array (2D Array)

• An array of arrays (often used to represent matrices).

• Example in Python:

  python
  arr = [[1, 2], [3, 4], [5, 6]]
  

---

🔹 3. Multi-Dimensional Array

• Arrays with more than two dimensions.

• Common in scientific computing (e.g., NumPy in Python).

• Example in Python using NumPy:

  python
  import numpy as np
  arr = np.array([[[1, 2], [3, 4]], [[5, 6], [7, 8]]])
  

---

🔹 4. Dynamic Array

• Arrays that can change size during execution.

• Example: Python's list, Java’s ArrayList, C++ vector.

---

🔹 5. Static Array

• Fixed size, declared at creation. Used in languages like C or C++.

• Example in C:

  
  int arr[5] = {1, 2, 3, 4, 5};
  

---

🔹 6. Jagged Array (Ragged Array)

• An array of arrays with different lengths (non-uniform).

• Example in C#:

  
  int[][] arr = new int[3][];
  arr[0] = new int[2];
  arr[1] = new int[3];
  arr[2] = new int[1];
