One-dimensional and Multidimensional Arrays

Arrays in C++ are used to store multiple values of the same type in a single variable.

// One-dimensional array
int arr[5] = {1, 2, 3, 4, 5};

// Accessing elements
cout << arr[0]; // Output: 1

// Multidimensional array
int matrix[2][3] = {
  {1, 2, 3},
  {4, 5, 6}
};

cout << matrix[1][2]; // Output: 6

Arrays have fixed sizes and are indexed starting from 0.
