Write a C program using threads and mutexes, whereby incr( ) is used to increment a shared float variable, decr( ) is used to decrement shared variable, double ( ) is used to double the shared variable, and halve( ) is used to halve the shared variable. Use mutex locks at appropriate places so as to synchronize the four threads. Initialize float variable to 64.0 in the beginning.
