Otherwise, the program will simply compile but the virtual function will not be overridden. Some of these possible mistakes are: Functions with incorrect names:For example, if the virtual function in the base class is namedprint(), but we accidentally name the overriding function in the derived...

In inheritance where base class and derived class have same function declaration but different definitionFunctionthen this is known asfunction overriding. To override a method, make the functionopenin base class and addprefixoverridebefore function definition in derived class. ...
Absolute value of 5.5 = 5.5 Working of overloading for the absolute() function In this program, we overload theabsolute()function. Based on the type of parameter passed during the function call, the corresponding function is called. Example 2: Overloading Using Different Number of Parameters ...

C++ lets you specify more than one function of the same name in the same scope. These functions are calledoverloadedfunctions, oroverloads. Overloaded functions enable you to supply different semantics for a function, depending on the types and number of its arguments. ...
Function Inheritance and Overriding A functions in a derived class with the same name and parameter types as a function in a base class overrides that function: class A { int foo(int x) { ... } } class B : A { override int foo(int x) { ... } ...

If the base class function isn't declared asvirtual, then the derived class function is said tohideit. Both overriding and hiding are distinct from overloading. Block scope is strictly observed. A function declared in file scope isn't in the same scope as a function declared locally. If ...
