C++ and Object Oriented Programming. Object Oriented programming is a programming style that is associated with the concept of Class, Objects and various other concepts revolving around these two, like Inheritance, Polymorphism, Abstraction, Encapsulation etc. The prime purpose of C++ programming was to add object orientation to the C programming language, which is in itself one of the most powerful programming languages. The core of the pure object-oriented programming is to create an object, in code, that has certain properties and methods.

Hi, I was asked the below question in one interivew. Imagine you're maintaining a big project which is having 50k+ lines of code and as part of enhancements, you received a request to add a functionality in one of the .cpp files. For this, you need to add a new function. How do you write a new fucntion without adding a prototype to the header file (because, if you add prototype in the headerfile, the compiler has to compile all the other files). So, the requirement is not to touch the header file but add functionality in the cpp file. How do you add? |
