You are given three classes A, B and C. All three classes implement their own version of func. In class A, func multiplies the value passed as a parameter by : class A { public: A(){ callA = 0; } private: int callA; void inc(){ callA++; } protected: void func(int & a) { a = a

Double ended queue or Deque(part of C++ STL) are sequence containers with dynamic sizes that can be expanded or contracted on both ends (either its front or its back). The member functions of deque that are mainly used are: Deque Template: std::deque<value_type> Declaration: deque&

You are given a class - Complex. class Complex { public: int a,b; }; Operators are overloaded by means of operator functions, which are regular functions with special names. Their name begins with the operator keyword followed by the operator sign that is overloaded. The syntax is: type operator sign (parameters)

Preprocessor directives are lines included in the code preceded by a hash sign (#). These lines are directives for the preprocessor. The preprocessor examines the code before actual compilation of code begins and resolves all these directives before any code is actually generated by regular statements. #define INF 10000000 if( val

A class template provides a specification for generating classes based on parameters. Class templates are generally used to implement containers. A class template is instantiated by passing a given set of types to it as template arguments. Here is an example of a class, MyTemplate, that can store one element

Solve the problem Inheritance-Introduction before solving this problem. In the previous problem we learned about Inheritance and how can a derived class object use the member functions of the base class. In this we will see what multi-level inheritance is. Suppose we have a class A which is the base
