HI all. I have started a new job recently where I am supposed to work with C++/ I have been doing programming in C language for past 5 years. I am looking for ways to get me up to an acceptable level in OOP. I have all the basic concepts of C++ and OOP but don't have much experience of actual class designing. What I really am looking for is ways to learn class library designing as I will be working in a team who is writing C++ libraries for other programmers to use. Please suggest principles like "responsibility assignment" which can help me design classes in general.

The problem is quite common when starting to learn C/C++.. the reason is that console applications once finisher return from their main method, the associated console window automatically closes. This behavior has nothing to do with what your app does or not, or if the app is working well or not.
The “ValueError : I/O operation on closed file” error is raised when you try to read from or write to a file that has been closed. If you are using a with statement, check to make sure that your code is properly indented.
You need to put in something to halt the program so you can see the output. One way of doing it is to ask the user to press the Enter key.
“The C [programming language's] memory management is considered close-to-the-metal compared to other application languages because one can easily see and do mathematics on actual hardware RAM addresses (or something pretty close to them).”
