C Function Overloading

Function overloading is a feature of a programming language that allows one to have many functions with same name but with different signatures. This feature is present in most of the Object Oriented Languages such as C++ and Java. But C (not Object Oriented Language) doesn't support this feature.

Why overloading is not possible in C?

Function overloading was introduced in C++, so it is not available in C. Polymorphism is an OOP concept, but C is not object-oriented.

What is function overloading explain with example?

Function overloading is a feature in C++ where two or more functions can have the same name but different parameters. ... Function overloading can be considered as an example of polymorphism feature in C++. Following is a simple C++ example to demonstrate function overloading.

What are the rules for function overloading?

Rules in function overloading

• The same function name is used for more than one function definition.
• The functions must differ either by the arity or types of their parameters.

How does function overloading work in C++?

C++ allows specification of more than one function of the same name in the same scope. These functions are called overloaded functions. Overloaded functions enable you to supply different semantics for a function, depending on the types and number of arguments.

Can we use polymorphism?

Polymorphism is the ability of an object to take on many forms. The most common use of polymorphism in OOP occurs when a parent class reference is used to refer to a child class object. ... In Java, all Java objects are polymorphic since any object will pass the IS-A test for their own type and for the class Object.

Can we overload main method?

Yes, we can overload the main method in Java, but When we execute the class JVM starts execution with public static void main(String[] args) method.

What is overloading and its types?

Overloading is what happens when you have two methods with the same name but different signatures. At compile time, the compiler works out which one it's going to call, based on the compile time types of the arguments and the target of the method call. ... Then it is called as Overloading.

Why is function overloading useful?

Advantages of function Overloading in C++

We use function overloading to save the memory space, consistency, and readability of our program. Function overloading shows the behavior of polymorphism that allows us to get different behavior, although there will be some link using the same name of the function.

What is function overloading and overriding?

Overloading occurs when two or more methods in one class have the same method name but different parameters. Overriding occurs when two methods have the same method name and parameters. One of the methods is in the parent class, and the other is in the child class.

What is the difference between overloading and overriding a method?

When two or more methods in the same class have the same name but different parameters, it's called Overloading. When the method signature (name and parameters) are the same in the superclass and the child class, it's called Overriding.

Which operators Cannot 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 .* .

What is overloading in OOP?

A major topic in OOP is overloading methods, which lets you define the same method multiple times so that you can call them with different argument lists (a method's argument list is called its signature). ... You can call Area with either one or two arguments.
