Hello! How are you? I am currently developing software with Qt but I will start with the "Version Controls" since I will be working as a team, but I can not connect directly with Github , what I want is that yes; I am modifying an Ej file: "Sistema.cpp" another member of the team can not open it until I finish modifying that file.
I really appreciate the help.
Exactly the philosophy of Git is the opposite of what you are proposing. In Git any modification is allowed between more than one user of the same file, this eliminates the idea of a sequential job, first I make some changes and when they are ready the next user can take it. In Git the problem is transferred to the one who wants to upload a change on something that was already modified, that's where the "Merge" comes in. The quick answer is with Git you can not do it, or at least not in a standard way.
