Mar 22, 2020 · A structure called Struct allows us to create a group of variables consisting of mixed data types into a single unit. In the same way, a constructor is a special method, which is automatically called when an object is declared for the class, in an object-oriented programming language.

A constructor that is not declared with the specifier explicit and which can be called with a single parameter (until C++11) is called a converting constructor. Unlike explicit constructors, which are only considered during direct initialization (which includes explicit …
