This repository holds solutions to some of the hackerrank problems in languages - C++, JAVA, BASH and PYTHON
Bourne again shell (Bash) is a free Unix shell that can be used in place of the Bourne shell. It is a complete implementation of the IEEE Portable Operating System Interface for Unix (POSIX) and Open Group shell specification.
Bash is basically a command processor that typically runs in a text window, allowing the user to type commands that cause actions. It can read commands from a file, called a script.
To get the functionality of Shell Scripting one must know some basic linux commands.
The origin of C++ dates back to 1979 when Bjarne Stroustrup, also an employee of Bell AT &T, started working on language C with classes. He borrowed desirable features from many other languages like Simula, Ada, ML, CLU and ALGOL 68. Thus, in addition to features of C language, C++ also included classes, strong type checking, default function argument and basic inheritance.
One of the speciality of C++ was that it uses OOP's Concepts i.e Object Oriented Programming concepts which made their way for several more features. These features are:
- Polymorphsim
- Inheritence
- Data Abstraction
- Modularity
- Encapsulation
