Question

For Example:

class A{

int b;
A *a1;
A *a2;

A(int c):b(c), a1(c), a2(c)  {}

}

I thought this was the way, but it doesn’t compile.
Is there a way to do this, or is it necessary to always use dynamic allocation?
thanks

Answer 1

You could simply initialize the pointers to null.

class A{

   int b;
   A *a1;
   A *a2;

   A(int c):b(c), a1(NULL), a2(NULL)  {}

}

(Note that if it complains about NULL not being defined, #include <cstddef>)

Or not initialize them at all.

class A{

   int b;
   A *a1;
   A *a2;

   A(int c):b(c)  {}

}
