    Question Delay A While Loop

    Good day !

    Is there any functions that allows me to slow down a while loop ?

    For example, I wish to display a list of numbers using a While loop and of cauz it's impossible to read all the values in the monitor since the processor speed is quite fast.

    So what should I do in order to have the while loop, loops once and then wait for specific of duration then only continue looping once and wait again and so on ?

    I remember there's a function that allows me do that but i can hardly remember what's that. I try to search around but failed.

    Thanks a lot !

    Hi. I don't know the library function, but I have one I modified from an example:

    //__Copyright 1997 Chris H. Pappas,Phd. __//

    int poz(int x)
    {
    long T1,T3,T2;
    T1=time(&T2);
    T3=(time(&T2)) + x;
    while(time(&T2) < T3);
    return(x);
    }

    //Calling syntax:

    poz(2); // ...will pause for 2 seconds

    I am sorry but I don't know the one that pauses for durations shorter than a second, but this should still work in your loops...
    Code:
    #include <cmath>
    #include <complex>
    bool euler_flip(bool value)
    {
        return std::pow
        (
            std::complex<float>(std::exp(1.0)), 
            std::complex<float>(0, 1) 
            * std::complex<float>(std::atan(1.0)
            *(1 << (value + 2)))
        ).real() < 0;
    }

    You could use either QueryPerformanceCounter

    BOOL QueryPerformanceCounter(
    LARGE_INTEGER *lpPerformanceCount // pointer to counter value
    );

    or timeGetTime

    DWORD timeGetTime(VOID);

    to get precision timing.

    Just use Sleep. Its defined in windows.h and it takes as a parameter the number, in milliseconds, that you want it to delay.
    example:

    Sleep(1000);

    would delay your program for 1 second.
