• Source Control Management (SCM), also known as Version Control or Revision Control, is a systematic approach to tracking changes and managing versions of source code and other files in a software development project.
• The primary purpose of SCM is to enable collaboration among developers, facilitate the organization and tracking of changes, and ensure the integrity and stability of the codebase over time.Here is a detailed description of key aspects of Source Control Management:
• A repository is a central database or storage location that holds the entire history of a project, including all versions of files and their associated metadata.
•  Repositories can be local (on a developer’s machine) or remote (on a server).
• Versioning involves assigning unique identifiers (usually numbers or hashes) to different versions of files within the repository.Each version represents a snapshot of the project at a specific point in time.
• A commit is a fundamental operation in SCM. It is the act of saving changes to the repository. Each commit includes a set of changes made to files, a commit message explaining the purpose of the changes, and a reference to the previous version.

Programming is an important stage in software development, but it is also a complex process that requires not only technical knowledge but also creative thinking. During programming, developers encounter various challenges, from searching for efficient algorithms to debugging code errors. With the advancement of technology and the emergence of new programming tools, developers constantly improve their skills. However, sometimes situations arise where there is not enough time to solve certain tasks, or the task proves to be difficult. In such cases, seeking help from experienced professionals can be beneficial. Don’t just look for someone who can do the job, but analyze your abilities and try to do possible on your own while choosing experts who can do homework for you.
