Question

I want to have a static array with arrays in it. I know you can make a normal array like this:

int test[] = {1,2,3,4};

But I want to do something like this (Xcode gives me a bunch of warnings and stuff):

int test[] = {{1,2}, {3,4}};

In python it would be:

arr = [[1,2], [3,4]];

What’s the proper way to do this?

Answer 1

To have a multidimensional array, you’d need two levels of arrays:

int test[][] = {{1,2}, {3,4}};

However, that will not work, as you need to declare the size of the inner-most arrays except the last one:

int test[2][] = {{1,2}, {3,4}};

Or if you need an even stricter type safety:

int test[2][2] = {{1,2}, {3,4}};
