Handling concurrent tasks in a functional manner

“

- [Instructor] Welcome to this example. In it we're going to explore concurrent tasks in C++ done functionally. So let's take a look at our code to see where we are. We have algorithm, future, hmm, iostream, vector, and thread. We have this function here, square, that's still empty, doesn't have anything in it. We have a collection of vector event numbers. We also have a collection of vector of future int which is called futures. We have a comment here that we need to launch task concurrently, and we'll get to that in just a minute. We have some more vectors. We're going to do a gather results from the futures, and then we're going to print everything out so that we can see what it is. So let's go ahead and start filling stuff in. We are going to begin with square, and square is going to do a std::cout. I'm going to say squaring space X, and X is the parameter that is passed into this function. And we're going to figure out what thread we're in. So we're going to do std::this_thread…
