►Lesson Description: In this lesson I show you the 'clamp' function. Clamp is a function that you may often find yourself writing -- but never fear, we have that function is available in the C++ STL! Clamp is useful for processing data, and it comes with 'const' for the parameters so that you return the value that you want. In this video I'll show you a little example for doing image processing, in which we might want to store values between 0 and 255 in a range. We'll also review some things like templates and .reserve in vectors for efficiency.
