Question

You can write like this:

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

but what if you want to use a pointer and allocate it with new?

int *test2;
test2 = new int[]{1,2,3,4};

This does not work, what is the syntax or is it possible?

Answer 1

This is one of the short-comings of current standard C++. Initialization is not uniform. Your best hope is uniform initialization in C++0x, but for the mean while you can assign the values after creating the array, e.g.

int *test2;
test2 = new int[4]; // Note that you still have to specify the size in C++0x
test2[0] = 1;
test2[1] = 2;
test2[2] = 3;
test2[3] = 4;
