Met a recruiter at a campus career fair. Got contacted for a technical phone interview. Interview was about a half hour and recruiter asked mainly questions about C++ programming. What's the difference between declaration and definition? What does the static keyword do? What does the inline keyword do? What does the volatile keyword do? What's the difference between int/long/short, and do they vary by compiler or OS? What's the difference between double/float? What is the C run-time library? What's the difference between a mutex and a semiphore? What is blocking? What are the pros and cons of static and dynamic memory allocation?
