New - initialization

[Lazaro Caruso]

Hi,
I thought that when I use new "with round brackets", it zeroes matrix, but today I found something strange. Here is the code:

int *t = new int[10]();

for(int i = 0 ; i < 10; i++)
    cout << i << ": " << t[i] << endl;

And here is my output:
0: 6956096
1: 6955792
2: 0
3: 0
4: 0
5: 0
6: 0
7: 0
8: 0
9: 0

Why t[0] and t[1] aren't zeros? I am using Code Blocks 8.02

That is supposed to be the case. An initializer of () should value-initialize the array, which value-initializes each element. For int objects, value-initialization means initialization with zero.

I guess there's a bug in the compiler. I have known other compilers have bugs with regards to value-initialization of int objects.

Mhm so it's all about compiler. Thanks for reply.

Code Blocks is an IDE that can be configured to use any compiler. Which compiler are you using?

Why don't you use a vector?
