What are multi-dimensional arrays in C++?

What are multi-dimensional arrays in C++?

Multi-dimensional arrays in C++ are arrays of arrays, allowing you to store data in multiple dimensions, like a matrix.

Can you give me an example of a 2D array?

Sure! Here's a simple example:

int matrix[3][4] = {{1, 2, 3, 4},
                     {5, 6, 7, 8},
                     {9, 10, 11, 12}};

How do I access elements in a 2D array?

You can access elements using the syntax matrix[row][column]. For example, matrix[1][2] gives you the value 7.

What about initializing a 3D array?

You can initialize a 3D array like this:

int cube[2][3][4] = {{{1, 2, 3, 4}, {5, 6, 7, 8}, {9, 10, 11, 12}},
                      {{13, 14, 15, 16}, {17, 18, 19, 20}, {21, 22, 23, 24}}};
