S1 is the calling object. The compiler converts s1<s2 to below function call :- s1.operator<(s2);

S1. As this is the object which appears on the left side of the operator, this is the calling object for it. Whereas S2 is the object which is passed as an parameter to the '<' operator function.

The function func is taking an object of Money class which is not defined in this scope so that will give a compilation error. It will give the error as "Money' was not declared in this scope ".

Its simple.
1. do calculate the sum of numbers from 1 till 100. is about (1+100)*(100/2)=5050
2. iterate and summarize all elements of container (array).
3. each number is unique in the container, so the difference between 5050 and the sum (from point 2) gives us an answer.

Runtime type identification (RTTI) lets you find the dynamic type of an object when you have only a pointer or a reference to the base type. RTTI is the official way in standard C++ to discover the type of an object and to convert the type of a pointer or reference (that is, dynamic typing). The need came from practical experience with C++. RTTI replaces many homegrown versions with a solid, consistent...

Overloading a method (or function) in C++ is the ability for functions of the same name to be defined as long as these methods have different signatures (different set of parameters). Method overriding is the ability of the inherited class rewriting the virtual method of the base class.

swarn kant

All the above answers are right this is one more refinement.overridding is runtime polymorphism while overloading is compile time polymorphism.

Overloading: the same function can perform different operations.overridding: the derived class can rewrite the content of the base class.
