Introduction to C++

C++ एक शक्तिशाली General Purpose Programming Language है जिसे System Software, Application Software, Game Development, Operating Systems, Embedded Systems, Database Systems तथा Competitive Programming में व्यापक रूप से उपयोग किया जाता है। यह C Language का Extended Version है जिसमें Object Oriented Programming (OOP) के Concepts जोड़े गए हैं।

आज भी C++ विश्व की सबसे लोकप्रिय Programming Languages में से एक है क्योंकि यह High Performance, Speed, Portability तथा Object Oriented Features प्रदान करती है। Engineering Students के लिए C++ सीखना अत्यंत महत्वपूर्ण है क्योंकि आगे के अधिकांश Programming Concepts इसी पर आधारित होते हैं।

Introduction

Programming Languages के विकास के दौरान C Language अत्यधिक लोकप्रिय हुई, लेकिन इसमें Object Oriented Programming के Features उपलब्ध नहीं थे। इस कमी को दूर करने के लिए Bjarne Stroustrup ने Bell Laboratories में C Language का विस्तार करके C++ विकसित किया।

C++ Procedural Programming तथा Object Oriented Programming दोनों को Support करती है। यही कारण है कि इसे Hybrid Programming Language भी कहा जाता है।
