In other words, functions with a similar name but having a different number of parameters or types of arguments are said to function overloading. A compiler calls correct function out of others on the basis of their number of parameters or datatypes in arguments.

However, changing only the return type of the function and keeping parameters and other aspects the same would make compiler confuse in choosing the correct function. Function overriding is a form of dynamic polymorphism that enables us to have an equivalent function in child class which is already defined in the parent class. A child class acquires member variables and member functions of its parent class.

If the number of parameters and type doesn't match by any method signatures, then it will give the compile time error. We can achive method overloading by changing the number of parameters used or by using different types of parameters or by changing the order of parameters Example. Method Overloading Method Overriding.

Creating more than one method or function having same name but different signatures or the parameters in the same class is called method overloading. Creating a method in the derived class with the same signature as a method in the base class is called as method overriding.
