Learning For Everyonea) Parameters with which functions are called
b) Parameters which are used in the definition of the function
c) Variables other than passed parameters in a function
d) Variables that are never used in the function
Formal parameters are those which are used in the definition of a function. They are the parameters that represent the actual parameters passed and they are the one which is used inside the function.
a) cin.get(ch)
b) getline(ch)
c) read(ch)
d) scanf(ch)
C++ provides cin.get() function to read a single character from console whereas others are used to read either a single or multiple characters.
a) procedural programming language
b) object oriented programming language
c) functional programming language
d) both procedural and object oriented programming language
C++ supports both procedural(step by step instruction) and object oriented programming(using concept of classes and objects).
a) Base class pointer object cannot point to a derived class object
b) Derived class pointer object cannot point to a base class object
c) A derived class cannot have pointer objects
d) A base class cannot have pointer objects
C++ does not allow a derived class pointer to point a base class pointer whereas Base class can point to a derived class object. Both base class and derived class can have pointer objects.
a) Class
b) Member functions
c) Constructors
d) Destructors
Virtual keyword cannot be used with constructors as constructors are defined to initialized an object of particular class hence no other class needs constructor of other class.
