This is question of data structures and algorithms the question is complete.. 

Convert the implementations (normal code of queue, circular queue and priority queue) of these data structures  into template-based C++

implementations.

 Queue

 Circular queue

 Priority queue (both approaches)

The code should be implemented strictly in C++ language. The use of C-language specific features, where an alternative C++ feature is available, is NOT ALLOWED.

IN CASE: if u cant do  all three then kindly do  atleast two (queue,circular queue)

and for priority queue u can change code from internet
