Question

static int (*g_data)[3];

I’d like to new N elements of int[3]. I’m only able to this as follows:

g_data = (int(*)[3]) new int[N*3];

I know that this is okay and using struct would be an alternative solution. But, just for curiosity, can I directly call new for int[3], i.e., without the type conversion?

Answer 1

Since g_data is a pointer to a 1D array of 3 int, to make an array of N such arrays of 3, you simply use int [N][3]:

g_data = new int[N][3];
