How do you see the object-oriented paradigm and how do you connect to the performance ? 5. How about the libraries? Have you worked with STL libraries ? Do you know about BOOST ? 6. What is memory management in C++ ? How do you handle memory management ? 7. When you create STL structures, one has to be careful on how these containers handle the object inside. Are you creating copies or references? 8. Did you ran into memory issues when the program is using all of your RAM? When you create heavy objects inside and didnt clean up, how do you clean up your objects ? Did you just delete or you use smart mechanisms ? 9. Do you know the boundary between shared pointer and unique pointer? When do you use this ? 10. You can get away with unique pointer and clean the memory by releasing the pointer when it is out-of-scope. So, where do you use shared pointer ? Or you can use directly shared pointer and create an overhead ? 11. How often do you test your code ? 12.
