Introduction to Arrays in C++

An array is a collection of elements of the same data type stored in contiguous memory locations. Arrays allow you to store multiple values in a single variable.

Declaring and Initializing Arrays

Syntax

data_type array_name[array_size];

Example: Declaring an Integer Array

int numbers[5]; // Declaration
numbers[0] = 10; // Initialization
numbers[1] = 20;
numbers[2] = 30;
numbers[3] = 40;
numbers[4] = 50;

Key Takeaways

  • Arrays store multiple values of the same type.
  • Array indexing starts at 0.
  • Access elements using the index notation array_name[index].
