Question

I am trying to translate a subset of Java to c++. How can i simulate imports(single and on-demand) in c++ ?

Answer 1

Java allows classes to use each other in their definitions, c++ does not:

class A{
 B m(){return new B();}
}
class B{
 A b(){return new A();}
}

So I guess it is not possible to retain the same import structure.

Easiest way – grab some java to c++ converter and look through the code it generates, might be useful.
