Question

Write a program that accepts a phrase of unspecified length onthe command line. For example:

prompt% letterprint Operating Systems Class at Kent-State

The main() in this program has to create two threadsrunning functions (vow and cons). The threads should take turnsprinting the respective words of the phrase supplied on the commandline. The vow thread should print all the words that start with avowel and the cons thread should print all words starting with aconsonant. Note that the main thread (running main()) should notprint anything itself – the output should be supplied by thethreads that it creates. The order of words in the phrase shouldnot be

changed in the printout. Your program should work for any phraseof any reasonable length, not just the

one given in the example. The output of you rprogram shouldlooks similar to the following

prompt% letterprint Operating Systems Class at Kent-State

vow:    Operating

      cons:    Systems

      cons:    Class

      vow:    at

      cons:    Kent-State

In this part you are not allowed to use synchronizationprimitives such as mutexes for thread coordination. You can usesched_yield() torelinquish control of the CPU.
