This template class is a custom duplication of the Standard Template Library (STL) queue class. Whether you like building your own data structures, you simply do not like to use any inbuilt functions, opting to build everything yourself, or your homework requires you make your own data structure, this sample code is really useful. I feel its beneficial building functions such as this, that way you better understand the behind the scene processes.

The highlighted lines are sections of interest to look out for.

The code is heavily commented, so no further insight is necessary. If you have any questions, feel free to leave a comment below.


Use of the above template class is the same as its STL counterpart. Here is a sample program demonstrating its use.

Once compiled, you should get this as your output

charQueue has 35 items in it and contains the text:

intQueue has 12 items in it.
The sum of the numbers in the queue is: -2817

doubleQueue has 11 items in it.
