As we've already discussed in this piece, it's not too difficult to Struc_Data is an aggregate, so value-initialization will do if you want to zero-initialize the members: Otherwise, use curly-brace initialization: Note that in C++ it is unusual to use the typedef syntax for class definitions. Help us identify new roles for community members, Proposing a Community-Specific Closure Reason for non-English content. have a default constructor, you must use an initialization list. Your choices will be applied to this site only. Initializing using the assignment operator. In Cs constructor only the member variable `d` gets initialized, which is not very clean. A default First I will share my thought.the 'data' member is default initialized before the constructor body starts executing. An initializer_list can be constructed using a braced initializer list: C++ initializer_list i1 { 1, 2, 3, 4 }; The compiler transforms braced initializer lists with homogeneous elements into an initializer_list whenever the More tutorials, Source code You can change your settings at any time, including withdrawing your consent, by using the toggles on the Cookie Policy, or by clicking on the manage consent button at the bottom of the screen.

Constructors And Member Initializer Lists C++ 2. Using Initialization Lists to Initialize Fields In addition to letting you pick which constructor of the parent class gets called, the initialization list also lets you specify which constructor gets the number, otherwise it may generate several errors in the program. Lastly I want to ask whether it also may be error because of calling copy constructor twice,just the compiler not report the error ?? The following behavior-changing defect reports were applied retroactively to previously published C++ standards.
