time reaction game

I need to create a piece of code that starts a timer and stops when a key is hit, and then displays how far away from 2.5 seconds that the key was hit. It needs to do this 4 times. I can use the clock() and kbhit() functions. The only problem is I can't reset the counter to ZERO for each time. If anyone understands and can help... please do. Thanks!

Instead of reseting the counter save the value of when they first hit it and subtract that from the current time.

Like:

Code:

---

// ...
double previous_time;
double current_time;
// do whatever to get the times;

current_time -= previous_time;

// that will give you how long it took from the first press to the second one.

---

Hope that helps and makes sense.

I have to display the time continually...

Thanks dude, that helped.
