What are some common challenges computer programmers face when working on large-scale software projects?

Computer programmers often encounter challenges such as coordinating with multiple team members, managing complex codebases, and ensuring that their code integrates smoothly with existing systems. Communication and version control become critical as the project grows, and programmers must be adept at using tools like Git and collaborating via code reviews. Additionally, balancing feature development with bug fixes and technical debt is a typical challenge, requiring strong organizational and problem-solving skills.
