Default Constructors in C++

This lecture introduces default constructors in C++, explaining how they are constructors without parameters or with default parameter values. Examples are provided to illustrate the concept, including how the compiler generates a minimal default constructor if none is specified. The lecture also covers grouping constructors using default parameter values, the implications of specifying at least one constructor, and how to reintroduce the default constructor in C++11. Additionally, it discusses the use of default and delete methods, calling other constructors within a class, and initializing attributes with default values in C++11.
