help with time.h and threads

[thewhisper]

I created a program to display time continuesly so it auto updates every sec but the issue is i cant integrate the code in the main program because to make time update continuesly it needs a loop a infinite loop so none of the rest program gets to work. My q is : is it possible to display time continuesly and make the rest of program continue normally? like a multi thread program because i want to display time every sec in the bottom of program. By the way this is console app not gui

The easy way is to make your input non-blocking.

do {
  if ( keyIsPressed() ) {
    readKey();
    processKey();
  }
  updateTime();
} while ( 1 );

If you're using functions like scanf or fgets, then all you need to do is make non-blocking versions of these, so that you can update time whenever you like.

[thewhisper]

Non blocking? So for example all my code goes below thw do whileloop? Also i have a technical difficulty i am suppose to display two random num but every time i restart the program it starts displaying the same pattern not the same number but same pattern of num why?

[Salem]

Perhaps it would be better if you posted some code, then we could give you direct answers.

Salem like i said it always prints same 3random nums sequence when i start the prog

[fnprintf]

it always prints same 3random nums sequence when i start the prog

rand() is pseudo-random number generator. Try srand() for more pseudo-randomness.

For threading, look at process.h and _beginthread().

I am dealing with graphics a lot and i have a problem with sdl and allegro i cant get a nice tut on both allegro 5 or sdl so i prefer simpke stuff like 2D MENU and simple graphics like the menu from borland turbo c that works with c purely which one you recommend me

Then you need to add to the start of main
srand( time(NULL) );
This sets the initial seed for the random number generator.

Salem help with this issue on graphics iam trying to make simple graphics just normal menu style lime borlnd turbo c but i cant get sdl to work or allegro so i prefer simple stuff for cmd prompt in windows i get tbe results using conio2 on dev c and codeblocks but i need too much code just to make a rectangle filled with blue and i know there must be better stuff out there to do this.
