Declaring Arrays

  • Arrays are declared using a specific syntax in programming languages like Java or C++.
  • Example: int[] numbers; declares an integer array named 'numbers'.
  • Declaration allocates memory but doesn't assign values yet.

Initializing Arrays

  • Initialization assigns values to the array elements.
  • Example: numbers = new int[5]; creates an array with 5 integer slots.
  • You can also initialize with values: int[] numbers = {1, 2, 3, 4, 5};.

Common Operations

  • Access elements using indices: numbers[0] gives the first element.
  • Loop through arrays using for or while loops for processing.
  • Arrays have fixed size once initialized in most languages.
