1. Definition and Purpose of Arrays Definition An array is a collection of elements of the same data type stored in contiguous memory locations. Purpose Arrays are used to store multiple values in a single variable, simplifying data manipulation and allowing for efficient operations.

2. Declaring and Initializing Arrays Syntax data_type array_name[size ]; Examples int numbers[5]; /* Declaration */
int numbers[5] = {10, 20, 30, 40, 50}; /* Initialization */

3. Declaring and Initializing Arrays Syntax: data_type array_name [size]; Examples: Declaration: int numbers[5]; Initialization: int numbers[5] = {10, 20, 30, 40, 50}; Partial Initialization: int numbers[5] = {10, 20}; // Remaining elements are initialized to 0

4. Accessing and Modifying Array Elements Accessing Elements are accessed using an index, starting from 0. Modifying Elements can be modified by assigning a new value to the desired index.

5. Array Operations: Traversal, Searching, and Sorting Traversal Iterating through all elements in an array. Searching Finding a specific element in an array. Sorting Arranging elements in a specific order.
