The main and most important difference between Virtual and Abstract Keywords is that Virtual method/property may or may not be overriden in the derived class. Whereas, in case of abstract keyword, you have to override the method or property, or else th...
The method to run is decided at runtime. The Shape class is written with ‘virtual’ keyword. The Rectangle and Triangle classes are written with ‘override’ keyword. If these keywords are not used, the output will print the content of the display method of Shape class for all....
The type "bool" is a fundamental C++ type that can take on the values "true" and "false". When a non-bool x is converted to a bool, non-zero becomes true and zero becomes false, as if you had written x != 0. When bool is converted to non-bool, true becomes 1 and false ...

Virtual properties allow inheriting classes to override them using theoverridekeyword. With virtual properties, we can provide a default behavior for the property in our class but st...
