You can use the clock() function.

Example:
#define <time.h>

clock_t start, elapsed_time;

main() {
start = clock();
while(1) {
--- here: your code ---
elapsed_time = (clock() - start)/CLK_TCK;
if (elapsed_time > TOPTIME) break;
}
}
Note: elapsed_time is in second.

Yes i understand your code . i tried this also .But what want to know is if suppose
i enter a code at --here; you code--
cin>>something;
and i set toptime as say 1000s
now consider the user has reached this cin>>something part and he is not getting a word to enter.So naturally he will keep on thinking what to enter for a long time (say for 10000s or 1/0s).but i want tosomehow cause the program to skip this waiting for a keybord as soon as 1000s are over and display "TIMEOUT!!! !!!" .

thank you for replying to my letter.
Hope you can resolve my problem.
thank you
