What is the role of version control systems in software development?

Version Control Systems (VCS) play a central role in software development, providing:

• Change tracking: They record every modification to the code, allowing rollback to previous versions in case of errors.
• Collaboration: They enable multiple developers to work on the same project simultaneously, minimizing conflicts.
• Branching and merging: They allow creating independent branches for developing new features or fixes, and then merging them back into the main branch.
• Backup and history: They serve as a reliable repository of the project's history, protecting against data loss.
• Audit: They enable tracking who made what changes and when.

Example of saving changes in Git:

# Adding files to the index for commit
git add .

# Creating a commit with a description of changes
git commit -m "Initial commit of project structure"

# Pushing changes to a remote repository
git push origin main
