What do you mean by MFC Collection Classes in visual programming?

Answer 1

MFC provides a number of ready-to-use arrays, lists, and maps that are referred to as collection classes. Using a collection allows the programmer to hold, process, or store groups of class objects or variables of certain standard types. You can use these collection classes to store objects in memory, and for some standard types they provide serialization support also. The collection varies in size to accommodate as many objects as memory constraints will allow. A collection object appears as a single object. Class member functions can operate on all elements of the collection. A collection class is characterized by its shape and by the types of its elements. The shape refers to the way the objects are organized and stored by the collection. MFC provides three basic collection shapes: arrays, lists, and maps (also known as dictionaries).
