No, but maybe you want a Factory?
Member 12384360 10-Mar-16 23:56pm
now what is factory here?
Before asking about possible or impossible, think at this: what would it possibly mean? The constructor creates an instance of a class. And why?
See, for example,

Also, why writing something in the section "What I have tried" without showing what you have tried? What exactly have you written?

No and you shouldnt do it, because it destroyes the class pattern of encapsulation. If you need to modify a class object it should always made with member functions.

I think you must rethink your software design. Learn from this tutorials.

The contructor must be (by definition) a member of the class. However you can put its definition outside of the class (declaration must be inside the class one):
// ctor.h header file
class A
  A(); // just ctor declaration

// ctor.cpp source file
#include <iostream>
#include "ctor.h"

// this is the ctor definition
A::A(){std::cout << "A()" << std::endl;}

int main()
  A a;
