Array Variable initialization

IMHO such a discrepancy would be too gross, even for VC6. :)

yes, probably, but it's not *THE* compiler to test the standard ! ;) ;P

0 works fine.

It is just a side-effect of default (int) initialization: you're actually initializing only the first array item. Try the following code:

#include <iostream>
using namespace std;

struct MyStruct
{
MyStruct():_i(-1), _j(0),_k(-1){ }
MyStruct(int a):_i(a), _j(a), _k(a){ }
int _i,_j,_k;
};

void main()
{
int i;
MyStruct a[5] = {0};
for (i=0; i<5; i++)
{
cout << i << ") {" << a[i]._i << ", " << a[i]._j <<", " << a[i]._k << "}" << endl;
}
}

This is why I only do it when setting things to 0. I use memset() otherwise.

The above is a wise approach. :)

For structs, I'd use memset(). I only use 0 for POD types.
