Interviews in the field of programming are all very similar, usually involving a whiteboard and an algorithm. Sometimes these questions are so incredibly simple, yet for whatever reason you can’t craft an answer on the spot. I’m going to start a series on some code snippets that are common to see in interview situations. All this code is in C++, for no other reason than it happens to be what I’m playing with the most right now.

The first in this series is one that comes easily to most, but I figured I’d start with something simple.

Problem:
Write a function to determine if a string starts with an upper case letter between A and Z.

Solution:

bool starts_with_uppercase(std::string suspect)
{
	if(suspect[0] > 'A' && suspect[0] < 'Z')
		return true;
	else
		return false;
}

More soon.
