Countdown & timer?

Hello!

I am currently trying to make a little game.

Basically, it picks a number say between 1 and 10, and you have to guess it.

I want to give the user 3 tries per guess with 5 guesses per round, and I want them to have 20 seconds per guess.

After they fail to get 3 guesses either by taking too long or using all their guesses, I want the game to end and to print a score. (in total seconds lasted)

I also want the game to get progressively harder (using a larger scale like 1-20, 1-30, etc.) and to give them either less guesses/less time to get it (randomly)).

I would like to have a countdown at the start that says "starting in 1... 2... 3... go!" to give them a chance to get ready, and also one between rounds.

I'm not sure how to go about this, so any help will be greatly appreciated!

Thanks!
You can use a sleep function for the timer.

#include <windows.h>
#include <iostream>

int main(void) {
        std::cout<<"This program will waste 15 seconds of time.";
        Sleep(15000);
        std::cout<<std::endl<<"Thanks for letting us waste your time...";
        std::cin.ignore();
}
here is my demo for one round, secret number random from 1 to 10, 5 guesses per round, 20 seconds per guess:

        Sleep(sensitivity);
    }
    cout << "\n";
    return atoi(input.c_str());
}


the hardest part is "to have 20 seconds per guess." I need both windows.h and conio.h (both non-standard) to do this...

Wow, that's awesome. Thanks!

I made a version myself without the timed thing, and I'd really appreciate your feedback!
