I am in my 2nd year of college .?
You can certainly use C or C++ for anything, since they have a long history and are general purpose programming languages. Now, realistically, your idea of a hospital management project is not an ideal fit for C or C++. I say this because that type of project would be very heavy on UI and database interaction, and these types of systems are usually built with web-technologies in the real-world (at the moment). If you do want to create such a project in C++, Qt is the best cross-platform GUI framework for C++ in my opinion. You can get the open-source version and use Qt Creator to develop your application, and it will build Windows/OSX/Linux fairly easily. A few caveats: Qt isn't pure C++, it uses a pre-compile step to add some features to the languages, such as "signals and slots". Qt doesn't take advantage of most of the modern C++ developments (C++11/14). Also remember: C and C++ are very different languages, and although C++ compilers will compile ~99% of C code found in the wild, that doesn't mean you should follow C idioms when writing C++ code. Pick up the Effective C++ series of books from Scott Meyers if you want to learn how to write quality C++ code. Many universities unfortunately don't actually teach good C++ practices, but essentially just a flavor of C with classes. Good luck!
