Question

I have a class obj1 that has no default constructor, and class obj2 that also doesn’t have a default constructor, and has as private variable an element of obj1:

I would like something like the following code – but actually this doesn’t compile, telling me that obj1 has no default constructor.

class obj1{
    obj1(some parameters){};
}

class obj2{
    obj1 _myObj1;
    obj2(some parameters){
        _myObj1 = obj1(some parameters)
    }
} 

any ideas?

Answer 1

Make the constructor of obj1 public and use initialization list in obj2.

class obj1{
public:
    obj1(some parameters){};
};

class obj2{
    obj1 _myObj1;
    obj2(some parameters) : _myObj1(some parameters) {
    }
};
