I'm new to Visual Studio, so I haven't gotten used to things yet. I've been using it for weeks with no problem, but today I've noticed that I have to click rebuild solution every time I make any changes to my code, otherwise it'll run an old version of the code. Is this a common thing? I've never had to do it until today, then all of a sudden I have to do it every time.

C has multiple stages, the compile stage to the link stage. If code changes, VS has to build (compile) and then link those changes into the app. If a library changes, then VS needs to link in the library changes.

If you are having to rebuild everytime, then VS is detecting some type of change to either a C file or a linked in library. Finding what is changing will tell you why you have to rebuild to keep the exe (app) current.

On a side note, if you are debugging and the debugger seems to step into comments/places it shouldn't be...then your code is in need of being (re)-compiled and linked. For the pdb (debug) files are out of sync with the textual code files that were changed and that is why the debugger is behaving as such.
