No enrollment or registration. Freely look through and use OCW products at your own personal tempo. There's no signup, and no start or end dates.

This might be described as a list of changes across the entire code foundation, but would most likely have big Advantages.

Efficiency: A switch compares in opposition to constants and will likely be superior optimized than the usual number of exams within an if-then-else chain.

volatile is used to refer to objects which are shared with “non-C++” code or hardware that does not Adhere to the C++ memory design.

What if there are less than n things within the array pointed to by p? Then, we read through some probably unrelated memory.
