Question

Let say I have a object. I’m assigning that to an integer.

MyClass obj1 = 100;//Not valid

Let’s say, I have a parameterized constructor which accepts an integer.

MyClass(int Num)
{
    // .. do whatever..
}

MyClass obj1 = 100;//Now, its valid

Likewise on any circumstance, does the vice-versa becomes valid?!.

eg) int Number = obj1;//Is it VALID or can be made valid by some tweeks

EDIT:

I found this to be possible using Conversion Functions.
Conversion functions are often called “cast operators” because they (along with constructors) are the functions called when a cast is used.

Conversion functions use the following syntax:

operator conversion-type-name ()

eg) Many have explained it neatly below

Answer 1

Yes, provided that the object is implicitly convertible to an int, either directly or through an intermediate object.

E.g. If your class have a conversion operator int it would work:

MyClass
{
public:
    operator int() const { return 200; }
};
