    sound and graphics in C - recommandation needed

    so i am programming for 2 years and i would like to use "sound" and "graphics" in my programes.
    i know the sound function and the graphics library in borland but after all it's borlan XD
    so I need you to recommend about an simple graphics (2D) interface and i need you to give me an example for using sound in C (I heard a little about the beep function).
    thx!! [:

    * hope I haven't pass the rules.

    SDL can do sound and graphics. Although for sound it does little more than play mp3s.

    There is the sound() function for Borland, but what you want is a music maker. Making music with sound() would be extremely laborious. Any program that can make music, will show you how to play that music, of course.

    This is the Borland C help file for sound:

    Code:
    sound   Turns PC speaker on at specified frequency.
    
     Syntax:
       void sound(unsigned frequency);
    
     Prototype in:
     dos.h
    
     Remarks:
    sound turns on the PC's speaker at a given frequency.
    
    frequency specifies the frequency of the sound in hertz (cycles per second).
    
    To turn the speaker off after a call to sound, call the function nosound.
    
     Return Value: None.
    
     Portability:
    sound works with IBM PCs and compatibles only. A corresponding function
    exists in Turbo Pascal.
    
     See Also:
      delay    nosound
    
     Example:
     /* Emits a 440-Hz tone (A above middle C) for 1 second. */
    
     #include <dos.h>
    
     int main(void)
     {
        sound(440);
        delay(1000);
        nosound();
        return 0;
     }
    Have you googled for music making programs and libraries?

    You will need a 3rd party library or engine to do sound.

    You may want to check out OpenAL.

    I think i wasn't clear enough, i don't wanna play\create music (like mp3), just sound in hertz..
    I'll very glad if you give me links or something for what you are suggesting.
    thank you both.

    Making sound in hertz is just what my last post's code and help was all about, what do you mean?

    Read the part in the code tags, and try the example code, in it.

    Gone are the days when you could hook a timer interrupt for timing and use the 8 khz PC speaker for sound based on the timer - or are they? A friend of mine at work coded something like this a very long time ago. Surprisingly it still works in a DOS window. He fires it up every now and then and we have a ball listening to some good old fashioned 8 khz PC speaker music. He actually encoded some old AC/DC songs. Just consider it an ancient form of MP3.

    that's what I want but this function is from borland (I use dev C++ and I prefer to have standart codes).

    for beep I must know api first?
    API is complicated )=

    rob, I have seen what you wrote somewhere but how do i control the sound? (if you can give me more details).

    last and likeable
    I didn't get you or you didn't get me.
    I am not traing to play songs XD

    thank you all [:

    Win32 API maybe?

    The manual page is pretty straight forward (http://msdn.microsoft.com/en-us/libr...77(VS.85).aspx). What do you want to know?

    If we wanted to implement Windows "Beep" in Borland code, it would looke like this:
    Code:
    BOOL WINAPI Beep(
      __in  DWORD dwFreq,
      __in  DWORD dwDuration
    )
    {
         sound(dwFreq);
         delay(dwDuration);
         nosound();
    }
    I don't think that makes it hard to do or deal with.

    Obviously, learning the ENTIRE Windows API is complicated, but understanding individual functions is (generally, and certainly in this case) simple.

    Beep

    I compiled this code (with borland)

    Code:
    #include <stdio.h>
    #include <dos.h>
    
    int main()
    {
         sound(700);
         delay(3000);
         nosound();
         return 0;
    }
    and all I heard was the silence..
    when I tried to compile the API part I got errors.

    Can you get other sounds out of the system? Is the PC speaker connected?

    The Beep() function requires that you include <windows.h>
