initialize members of a class

[vagelis]

i have a class

class A{
int a=0;}

and i get an error
'A::a' : only static const integral data members can be initialized within a class

i get errors like this and if i write
const int a=0;
or
static int a=0;
or
static const int a=0;

any idea??

Unfortunately C++ does not yet support this very intuitive way of initialization. You have got to write is as follows:

class A{
A: a(0) {}
int a;}

Sorry!

Member variables should be initialized inside a constructor, or using an initialization list:

#include <iostream>
using namespace std;

struct A
{
    int a;

    A() { a=0; }
};

struct B
{
    int b;

    B():b(1) {}
};

int main()
{
    A a;
    B b;

    cout << a.a << endl;
    cout << b.b << endl;

    cout << "\nhit enter to quit...";
    cin.get();
    return 0;
}

EDIT: Damn... Too slow...
