In the following example, we are defining three different functions with the same name but different parameters. This example demonstrates the implementation of function overloading −Open Compiler #include<iostream> using namespace std; // Adding two integers (Function definition 1) int addition(...
The C++ compiler selects the proper function by examining the number, types and order of the arguments in the call. Function overloading is commonly used to create several functions of the same name that perform similar tasks but on different data types. ...

There is two functions say doSomething which takes one argument int and string making them overload... doSomething (5) would obviously call int version and linking would happen at compile time... There is no vtable involve in overloading... Same way , doSomething ("Hi") will call ...

Is what we have in lesson 11.12 "Const class objects and member functions" a different thing? I mean getValue() function in this snippet about "Overloading const and non-const function": #include<string>classSomething{private:std::string m_value;public:Something(conststd::string&value="")...
Easy. Just create another test function in the derived class that calls the base explicitly, like so: Copy Copy Copy Copy Copy class D : public B { public: virtual void test(int x) { B::test(x); } ••• }; Now D has both test functions and everything is ...
One of the nice features of C++ is that you can give special meanings to operators, when they are used with user-defined classes. This is calledoperator overloading. You can implement C++ operator overloads by providing special member-functions on your classes that follow a particular naming ...
