3. Source Control
Source control, often known as version control, is the method used in software engineering to monitor and manage changes made to the source code over time. It is done through version control systems (VCS). VCS enables developers, designers, and everyone involved in developing a project to work together.
Today’s organizations heavily rely on version control systems, like Git, SVN, and Mercurial, to manage their projects by allowing team members to collaborate. Also, every individual can access the latest changes made to the source code.
4. Text Editors
A text editor is a piece of software that allows anyone to create and edit text files. In the programming world, a text editor is often referred to as a source code editor that lets developers or programmers write and edit the source code of applications.
Text editors are the most basic need of every programmer or developer, whether a seasoned programmer or a newbie. They are a crucial tool in the daily lives of programmers since they increase the efficiency of developing code. As a software engineer, you should be able to work with at least the popular text editors, such as Notepad++, Sublime Text, Atom, Brackets, and Visual Studio Code.
