How to call constructor in the constructor ???

Hello,


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

A::A() {
//how to instance the A(1) here
}

A::A(int a) {
cout << a;
}



As in the above code, how can I add a statement that can instance the A(int)
in the A() constructor ???

You cannot call one constructor from another in C++.

A couple of alternatives:

class A
{
public:
A(int a=1);
};

class A
{
void Init(int a);

public:
A()
{
Init(1);
}

A(int a)
{
Init(a);
}
};

-cd
