What is C implementation of queues?

Answer:

Answer

It depends on the type of data, but generally you would just implement a data array and have a static pointer to the "next" element of the array and a static pointer to the "last" element of the array. New data would be added to the location of the "last" pointer. Data would be processed from the "next" pointer. Pointers would be incremented to the appropriate element whenever reading or writing and special attention given to any time you come to the end of the array.
