u can go for dual core and then multiprogrammin g or multithreading .bcos in a single core even if u have all the application running its not running at the same time .

Dual core or not, you need to spawn a thread.

How you do this is a little diffferent between Unix and Windows though the concept is the same:

1) your thread is a function with prototypoe that fits a pattern:
Windows: DWORD WINAPI ThreadProc(LPVO ID);
Unix: void* ThreadProc(void *):

2) You call an operating system function to create the thread and start it
Windows: CreateThread()
Unix: _pcreate_thread ()

3) Your thread runs until the function completes. Then it dies.

4) You may have communicate with your thread. Here you will need semaphores.

5) Now a a good time to reasearch multithreading in your operating system.
Windows: Plenty of info in MSDN.
Unix: Use Google.

Multi threading program u can do . but one thread might be ruuning even if u write many threads in an application. if u practically want threads to run in parallel at the same time then hyperthreading technology or use dual core machine.

i need the solution for that problem in c language.....

U can try for pthread or boost threads. Look for them on internet.
