One of the exercises in TC++PL asks:
Write a function that either returns a value or that throws that value based on an argument. Measure the difference in run-time between the two ways.
Great pity he never explaines how to measure such things. I’m not sure if I’m suppose to write simple “time start, time end” counter, or are there more effective and practical ways?
For each of the functions,
and compare the results. That’s about as practical as performance measuring gets.
