What is C++?
C++ is an "object oriented" programming language created by Bjarne Stroustrup and released in 1985. It implements "data abstraction" using a concept called "classes", along with other features to allow object-oriented programming. Parts of the C++ program are easily reusable and extensible; existing code is easily modifiable without actually having to change the code. C++ adds a concept called "operator overloading" not seen in the earlier OOP languages and it makes the creation of libraries much cleaner.
C++ maintains aspects of the C programming language, yet has features which simplify memory management. Additionally, some of the features of C++ allow low-level access to memory but also contain high level features.
C++ could be considered a superset of C. C programs will run in C++ compilers. C uses structured programming concepts and techniques while C++ uses object oriented programming and classes which focus on data. Read about the History of C and also about the History of C++.
To write and exicute C++ program you need some step which is given below:-
- The #include directive
- Header files
- The main() function
- The return statement
- The exit() function
- The newline character (\n)
- The void data type
- Translating a C program into an executable file
A First C++ Program:-#include <iostream.h>
cout<<"First C++ program.\n";
