Initializing Multidimensional Arrays in C++

Just as you can initialize a single-dimensional array by using braces and separating the elements by commas, you can initialize a multidimensional array with braces and commas and all that jazz, too. But to do this, you combine arrays inside arrays, as in this code:

int Numbers[5][6] = {
    {1,2,3,4,5,6},
    {7,8,9,10,12},
    {13,14,15,16,17,18},
    {19,20,21,22,23,24},
    {25,26,27,28,29,30}
};

The hard part is remembering whether you put in five batches of six or six batches of five. Think of it like this: Each time you add another dimension, it goes inside the previous dimension. That is, you can write a single-dimensional array like this:

int MoreNumbers[5] = {
    100,
    200,
    300,
    400,
    500,
};

Then, if you add a dimension to this array, each number in the initialization is replaced by an array initializer of the form {1,2,3,4,5,6}. Then you end up with a properly formatted multidimensional array.
