We have modified the above Example with this pointer to make use of initializer list in the following program. #include <iostream> using namespace std; class Sample { private: int num; char ch; public: Sample(int num,char ch):num(num),ch(ch){ ...
the values inside the body of the constructor, then a temporary object would be created which will be provided to the assignment operator. The temporary object will be destroyed at the end of the assignment statement. Creation of temporary object can be avoided by using initializer list. ...

This example was simplified from a larger operational code base that compiled just fine with prior compilers (VS 2022 17.9.x?) and initialized astd::vectorrather than astd::initializer_list. The temporary workaround of initializing objects individually and then putting them in thestd::...
In C++11 an initializer-list is a way to assign content to an object, when several literals are required. Example, you could initialize a list like: std::list<int> myList{1,2,3,4,5}; You may write your class, so it accept such syntax. As a minimalist example, the following func...
