C++ is a programming language that is implemented on a wide variety of operating system platforms and used for hardware design. This language has following features: •Compiled, •Statically typed, • Multi-paradigm and •Free-form. This Language also consists of both high-level and low-level language features. Here is a list of C++ Interview questions with answers which are asked at the time of campus interviews, placements and we have attached pdf also. C++ Interview Questions with Answers:- 1. What is C++? C++ is created by Bjarne Stroustrup of AT&T Bell Labs as an extension of C, C++ is an object-oriented computer language used in the development of enterprise and commercial applications. Microsoft’s Visual C++ became the premier language of choice among developers and programmers. 2. Define inheritance? The mechanism of deriving a new class (derived) from an old class (base class) is called inheritance. It allows the extension and reuse of existing code without having to rewrite the code from scratch. Inheritance is the process by which objects of one class acquire properties of objects of another class. 3. Define Constructors? A constructor is a member function with the same name as its class. The constructor is invoked whenever an object of its associated class is created. It is called constructor because it constructs the values of data members of the class. 4. What is the difference between C & C++? C++ is an object oriented programing but c is a procedure oriented programing. C is super set of C++. C can’t support inheritance, function overloading, method overloading etc. but C++ can do this. In c-program the main function could not return a value but in the C++ the main function should return a value. 5. What do you mean by implicit conversion? •Whenever data types are mixed in an expression then C++ performs the conversion automatically. •Here smaller type is converted to wider type. Example : in case of integer and float integer is converted into float type. To get more Questions and PDF file must go through this article .
