im making a timer program. that when a user dont input something in a specific time. the program will go to another menu
so far in my research. threads would be the solution to this. but in my current status right now as a c++ programmer. i dont think im capable of handling threads yet.
any suggestion to how to solve this problem would be greatly appreciated..
ps
dont want to use third party. im not allowed to use them
Jump to Postyou could use some os-specific api calls such as Sleep()(ms-Windows) or sleep() (*nix) in a loop to delay a bit then check for keyboard hit.
Jump to PostI don't know of any C/C++ function that waits for user input for a finite/specified time.
Which means you'll have to use multi-threading for sure.
See this thread if it helps.
Jump to PostPerhaps start by saying what kind of program you're writing (console, GUI) and for which Operating System.
It's really hard to make sensible suggestions without a decent level of background information.

whats the function that waits for a keyboard input?
in assembly i know that there is a code to doesnt need to press enter to input. it you can loop it so it can act like a timer. but whats the equivalent code for c++?

the link leads you to an error page.
if i have no choice at all i will use multi threading. or just dump this feature in my program.

its a console based and windows operating system

Found it using a search.. anyway if you look at the URL you would've figured what the problem is !
Here is the updated one: http://www.daniweb.com/forums/thread71946.html
sorry dude. anyway the link was kinda helpful thanks.
threads are still my last option. anyway tomorrow if i dont find one il have to learn threading
depending on the compiler there is a non-standard function in conio.h kbhit() that returns true if there is a key waiting at the keyboard buffer.

Scroll down the to "And now for a Windows specific solution:"
This enables you to read input without waiting.
Couple this with a loop which repeately calls say time() to measure how much time has elapsed. The loop exits when either a key is pressed or the time limit is reached.
