c - Getting wrong value for ID in pthreads -

I'm trying to be my output

  Starting proforma started at Professor 3 But never got me "Professor started 1" when num_professors = 2. I think that creating an array of ID will save the entire passing of the ID, but apparently not. I have about 70 other things for this project and it is quite frustrating to say at least one obstacle on this simple thing (maybe taking a few seconds to decide). Thanks much appreciated

this line:

  if (pthread_create (& Amp; Professor [i], NULL, Professor Funk, P)! = 0) { 

should be:

  if (pthread_create (& amp; Professor) [I], Faucet, Professor Phank, and P [Ii])! = 0) {
