Method Overloading
Method Overloading is the common way of implementing polymorphism. It is the ability to redefine a function in more than one form.
A user can implement function overloading by defining two or more functions in a same class sharing the same name, but with different method signatures (i.e. the number of the parameters, order of the parameters, and data types of the parameters).
Method overloading can be achieved by the following:
By changing the number of parameters in a method
By changing the order of parameters in a method
By using different data types for parameters
Suppose we want addition, but with different types, we can achieve like following easly.
Since both methods are doing same thing, so Instead of defining two methods that should do the same thing, it is better to overload one.
In Case of Method overloading, compiler identifies which overloaded method to execute based on number of arguments and theiry data types during compilation itself.
Overloading Vs Overriding Vs Inheritance
Overloading has different function signatures while overriding has the same function signatures.
Inheritance refers to using the structure and behaviour of a superclass in a subclass.
Rules of Method Overloading
1. Do not use ref or out modifiers in overloaded members.
