Question

In the following block of C++ code:

class student
class CIS: public student
{
};
class John protected CIS
{
};
The above block of code shows the concept of
A. Polymorphism
B. multiple inheritance
C. multi-level inheritance
D. multiple Polymorphism

Answer 1

The C++ code provided is intended to represent an inheritance hierarchy but has syntax errors, making it unclear which inheritance concept is depicted.

Step-by-step explanation:

The block of code provided shows a concept in object-oriented programming, particularly in the inheritance hierarchy of C++ classes. However, there is an error in the code syntax as class definition must be followed by a pair of curly braces {}. Also, the 'protected' keyword is used incorrectly as it should be followed by a colon when specifying access specification for inheritance, not braces. The intended hierarchy seems to be that the class CIS is a child of the class student, and another class John is somehow related to CIS. Without a proper relationship established (due to syntax errors), we cannot conclusively determine if it's an example of multi-level inheritance, multiple inheritance, or some other concept.
