client -server problem

Hey,

I am running cleint-server program in a single machine.

./server 90 in one cmd prompt.
./client in another one... here it is giving error 'no host port' If I enter some no.90...same thing...

what is the solution?

Let me find my crystal ball...

Did you not write the software? If the software isn't yours, consult the person/people who actually wrote it. Otherwise, two cryptic command lines and an equally cryptic error message will get you nowhere. If you want help here, give more info, but if this isn't related to C Programming, you're in the wrong place.

I might try: ./client localhost ./client localhost:90 just for kicks too.

At any rate, the answer you seek is 42.
