Learn how the STL algorithm library includes a number of useful functions for operating on a range of elements in a container.
- [Instructor] The algorithm header…has a number of useful template functions…for operating on a range of elements.…Here I have a working copy of algorithm.cpp…from chapter six of the exercise files.…The functions in the algorithm header…are varied and we'll get into the details later…in this chapter.…For now, I just wanted to take a look at a couple of them…to give you an idea of what's going on here.…So the algorithm functions are in the algorithm header…and here we have a vector of prime numbers,…less than a hundred out of order so that we can sort them.…
Here is a sort function from the algorithm header…and there's also a binary search function…from the algorithm header and so when I build and run,…you'll see that the sort function…sorts these prime numbers into order…and the binary search function is looking for the number 42…which we know is not a prime number.…There's only one even prime number…and that's the number two.…
So it's not going to find 42.…On the other hand it will find 47,…and so if I come here and I say 47,…
