RE: [Dev-C++] Timing

[Stein N. <tem...@of...>]

Try this;  :-)



1)

#include <stdio.h>
#include <conio.h>
#include <time.h>

void get_answer(void)
{
    clock_t start, end;

    start = clock();                                  /*Start the timer*/
    while(!kbhit())                                   /*While no one presses a 
key*/
    {
        end = clock();                               /*Get the new time*/
        if((end-start)/CLK_TCK >= 5)    /*Max time for question-answer is 
5seconds*/
        {
            printf("Out of time!");                /*Some 
out-of-time-message*/
            return;                                      /*Exit the 
answer-function*/
        }
    }
    if(getch() == '1')                               /*If the right answer 
should be key 1 pressed*/
        printf("YES, that's the right answer!");
    else                                                /*If key different 
from '1' is pressed*/
        printf("NO, that's not it!");
}




2)

#include <dos.h>

void main(void)
{
    sound(440);            /*Play a sound with frequency 440*/
    delay(1000);           /*Wait 1 second*/
    nosound();              /*Stop playing sound*/  
}


Mail if something does'nt  work!... hope it does! :)
