C++ in Linux

C++ is a powerful programming language that is widely used for system programming, game development, and software development. Linux is one of the most popular operating systems among developers, and it provides a complete set of tools and libraries for C++ development.

Installing C++ in Linux

To install C++ on Linux, you need to first make sure that the software packages are up to date. You can use the package manager of your Linux distribution to install the latest version of C++ compiler.

In Ubuntu, you can install the g++ compiler by running the following command in the terminal:

sudo apt-get update
sudo apt-get install g++

Compiling C++ code in Linux

Once you have installed the C++ compiler, you can use it to compile your C++ code. To compile your code, you need to create a file with .cpp extension and save it in a directory.

To compile a C++ program named "program.cpp", you can run the following command in the terminal:

g++ program.cpp -o program

This command will create an executable file named "program" that you can run by typing "./program" in the terminal.

C++ Libraries in Linux

Linux provides a wide variety of C++ libraries that you can use to develop your applications. Some of the popular ones include:

1. Boost C++ Libraries: Boost provides a set of high-quality libraries that extend the capabilities of C++.

2. Standard Template Library (STL): The STL is a collection of generic algorithms, containers, and iterators that are widely used in C++ programming.

3. Qt: Qt is a cross-platform application development framework that provides a set of C++ libraries for developing GUI applications.
