Inline array initialization

Question

I was used to using

new int[] {1,2,3,4,5};

for initializing array. But it seems nowadays, this does not work anymore, i have to explicitly state how many elements there are, with

new int[5] {1,2,3,4,5};

so compilers forgot how to count ?

And to make this a closed question, is there a way to omit the number of elements ?

Solution 1

This has never worked in the current version of C++, you have only been able to zero-initialize (or not initialize) dynamically allocated arrays.

What has always worked is non-dynamically allocated array initialization:

int myarray[] = {1, 2, 3, 4, 5};

Perhaps you are confusing it with this?

Even in C++0x it is not legal syntax to omit the explicit array size specifier in a new expression.

Solution 2

C++ have never allowed to initialize array with an unknown size of elements like above. The only 2 ways I know, is specify the number of elements or use pointers.
