Yes. Any base class method that is declared virtual can be overridden by a derived class. Overriding a method that is not declared virtual can still be called, but will not be called polymorphically. That is, if you call the base class method, the base class method will execute, not the override. To call a non-virtual override you must call it explicitly.

RossYes, member function overriding in a derived class is allowed in C++, but only if the function is declared public or protected.
Keep in mind that overridding and overloading are two different things, with overloading being the declaration and definition of two or more functions with the same name and scope, but with different numbers and/or types of parameters. Overloading is not related to derivation/overriding, so overloading is always allowed.
Overriding in C++ is when a method of a base class is "replaced", so to speak, in a derived class with a method of the same name, type, and parameters. In order for this to be possible, the base class must declare the method either protected or public. The base class' version of the method will be used for instances of the base class, while the derived class' version of the method will be used for instances of the derived class.
Overriding means to provide a new implementation for an existing method. The existing method must be inherited from a base class.
Overloading means to provide the same method name, but with a different signature, to cater for the different parameter types the method can accept.
Overloaded methods inherited from a base class can also be overridden in a derived class.

What is the difference between overloading and overriding methods in object?
Here are some of the most common differences between both of them. If you are working in Java for more than 1 year, you might be familiar with all of them but any way its good revision: 1) First and major difference between Overloading and Overriding is that former occur during compile time while later occur during runtime. 2) Second difference between Overloading and Overriding is that, you can overload method in same class but you can only override method in sub class. 3) Third difference is that you can overload static method in Java but you can not override static method in Java. In fact when you declare same method in Sub Class it's known as method hiding because it hide super class method instead of overriding it. 4) Overloaded methods are bonded using static binding and Type of reference variable is used, while Overridden method are bonded using dynamic bonding based upon actual Object. 5) Rules of Overloading and Overriding is different in Java. In order to overload a method you need to change its method signature but that is not required for overriding any method in Java.
What is the scope of method overloading and overriding?
Overloading happens when you have multiple methods in the current class that have the same name but different signature. The scope of method overloading is "Within the current class" Overriding happens when your current class extends another class (the parent class) and provides implementation for a method that is already available in the parent class. The scope of method overriding too is "Within the current class"
What is method overloading and constructor overloading explain with?
method overriding :method overriding means redefine methods in sub classes they already defined in the Super classes.method overloading : It means methods with the same name but with a different signature exist in one class
Why you use overloading and overriding?
Overloading the same method name with different number of arguments (and the data types), and perhaps with a different returned data type. The method signatures are different, only the names are the same. Overriding is to change the same method name with different implementation (the method body). The method signature stays the same.
Is constructor overloading same as method overloading.yes or no. explain?
yes,because in constructor overloading constructor have same and different parameter list. In method overloading method have same name and different parameter list.
