Which function Cannot be overloaded C++?
2) Member function declarations with the same name and the name parameter-type-list cannot be overloaded if any of them is a static member function declaration.
For example, following program fails in compilation.
3) Parameter declarations that differ only in a pointer * versus an array  are equivalent..
How many data members can a class contain?
Explanation: Any class can have as many data members as required. The only restriction that may arise is when there is not enough memory space. This gives flexibility to define a class with best properties possible. 6.
What operators Cannot be overloaded?
Operators that cannot be overloaded in C++? “.” Member access or dot operator.? “? : ” Ternary or conditional operator.? “::” Scope resolution operator.? “. *” Pointer to member operator.? “ sizeof” The object size operator.? “ typeid” Object type operator.
Can method overloading be done in different classes?
Overloading can happen in same class as well as parent-child class relationship whereas overriding happens only in an inheritance relationship. It is a valid question since usually, overloading is explained using two methods with the same name (but different parameters) in the same class.
What are the advantages of method overloading?
Advantages of method overloading in java Method overloading increases thereadability of the program. Overloaded methods give programmers theflexibility to call a similar method for different types of data. Overloading is also used on constructors to create new objects givendifferent amounts of data.
Which type of function Cannot be overloaded?
Function declarations that differ only by its return type cannot be overloaded with function overloading process. Member function declarations with the same parameters or the same name types cannot be overloaded if any one of them is declared as a static member function.
Can C++ be overloaded?
Most can be overloaded. The only C operators that can’t be are . and ?: (and sizeof , which is technically an operator). C++ adds a few of its own operators, most of which can be overloaded except :: and .
Can constructor be overloaded in derived class?
Explanation: The constructor must be having the same name as that of a class. Hence a constructor of one class can’t even be defined in another class. Since the constructors can’t be defined in derived class, it can’t be overloaded too, in derived class.
Why would a class provide overloaded constructors?
Overloading thus allows a class to be instantiated, and allows multiple methods of a class with the same name to be called, using different arguments. … For classes, constructor overloading provides both the convenience and power of being able to instantiate the same type of object using different sets of initial data.
Is overloading possible in inheritance?
In the inheritance hierarchy, superclass and subclass methods can be overridden and overloaded. … when overridden, superclass and subclass methods have the same name and the same parameters type signature (see Figure 1);
Why is method overloading useful?
It is used when a class that extends from another class wants to use most of the feature of the parent class and wants to implement specific functionality in certain cases. Overloading in Java is the ability to create multiple methods of the same name, but with different parameters.
What are overloaded constructors?
Constructor overloading is a concept of having more than one constructor with different parameters list, in such a way so that each constructor performs a different task. For e.g. Vector class has 4 types of constructors.
What happens if a user forgets to define a constructor inside a class?
Also if any user forgets to define init() function then no object will be initialized whereas if any constructor is not defined in any class the class provides a default constructor for initialization.
Can constructor be private?
Yes, we can declare a constructor as private. If we declare a constructor as private we are not able to create an object of a class. We can use this private constructor in the Singleton Design Pattern.
Can constructor be overloaded yes or no?
Yes! Java supports constructor overloading. In constructor loading, we create multiple constructors with the same name but with different parameters types or with different no of parameters.
Can a constructor be overloaded in C++?
Constructor Overloading in C++ We can use the same name of the functions; whose parameter sets are different. Here we will see how to overload the constructors of C++ classes. The constructor overloading has few important concepts. The constructor is called based on the number and types of the arguments are passed.
Can method be overloaded?
Method Overloading is a feature that allows a class to have more than one method having the same name, if their argument lists are different. It is similar to constructor overloading in Java, that allows a class to have more than one constructor having different argument lists.
Can we declare an overloaded method as static and another one as non static?
The answer is, No, you can not override static method in Java, though you can declare a method with the same signature in a subclass. … As per Java coding convention, static methods should be accessed by class name rather than an object. In short, a static method can be overloaded, but can not be overridden in Java.
