Some sort of explanation as to why they’re using “std::string on_off_attempt;” instead of just “string on_off_attempt;” would have been helpful. I spent 20 minutes googling this when it could have just been included as a note at the bottom of the lesson.

For those who came here for the same reason, these are the resources I found useful:

I don’t know if this was implemented in some way, but my code didn’t have it show up. `#include

int main() {

// Conduct IT support
std::string on_off_attempt;
std::cout << “Hello. IT.\n”;
std::cout << “Have you tried turning it off and on again? y/n\n”;
std::cin >> on_off_attempt;

// Check in with Jen
std::cout << “Oh hi Jen!\n”;

// Conduct IT support again…
std::cout << “Hello. IT.\n”;
std::cout << “Have you tried turning it off and on again? y/n\n”;
std::cin >> on_off_attempt;

// Check in with Roy
std::cout << “You stole the stress machine? But that’s stealing!\n”;

// Conduct IT support yet again…zzzz…
std::cout << “Hello. IT.\n”;
std::cout << “Have you tried turning it off and on again? y/n\n”;
std::cin >> on_off_attempt;`

This was the code for the lesson, but I decided to type the letter “n” to see what would happen and it’s giving me messages that aren’t in the code I don’t know if when you guys made this lesson you made a little easter egg or something?

For example “Is the light on the side glowing” and “Yeah, you need to turn it on”

Is this a skit from IT Crowd? I am not getting it.
