Error how can i run a process for a whole minute?

here's the problem, i have two processes that i need to run and both process should be run at a total of 1 minute each. how do i do that? and one more here's what the processes do: the 1st process show the '+" sign infinitely while the 2nd process displays the "-" infinitely. how could i count the number of times each signs have been displayed.

thanks in advance.

Homework eh? You should look at signal handling and the alarm() function. And about the + and - that are printed, look at having a counter for each process.

And another thing. This forum has a no homework rule too. So please do not post any more homework treads. They will be locked. Infact, I am locking this thread too.
