Title Body

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.
