This is very trivial question regarding the use of a constructor in C++. I will present in the form of an interview dialogue (it was difficult to present it in any other forms)
interviewer - what is a constructor?
me - constructor are special functions which makes sure that all objects are initialized before their use.
interviewer - what is an initializer list?
me - that is a list where all the initialization happens. A constructor's body is entered only after all the data members are initialized, or some constructor of all the member objects are called.
interviewer - that means initialization is carried out in initializer list, not inside constructor. But you said constructor initialize the object! Didn't you? Do you want to answer my first question.
me - I think constructor does assignment, it calls assignment operator on already initialized member objects.
So my question to you can be
how initializer list works?
what lies between function's starting address & starting braces [{]?
or just answer me how to convince my interviewer.
