How will I loop this without losing the

How will I loop this without losing the values of the variables?

I am a beginner when it comes to c++ programming please bear with me.

I know that returning to main() is not a good idea and if anyone of you know how will I loop the program to go back to the position selection when the voter is done voting for the last position.

when I run the program it seems fine. getting the votes from President to PRO Position is fine. The problem is how will the next voter vote without losing the vote (tally) of the previous voter?

FLOW:
SELECT POSITION (a-e) ---> SELECT A CANDIDATE (a-c) ---> (this goes on until the position of PRO) ---> ( then go back to the POSITION SELECTION)

*note: after every vote there is a case statement for which I can choose to vote for the next position, quit, or show results (and after showing the results it will go to the next position to vote).

Sorry for my bad english.
Thanks

For loops, look at "control structures":
http://www.cplusplus.com/doc/tutorial/control/

You'll find useful loops such as the while and do-while loop.

Also, attempt to avoid <conio.h> and direct calls to system().
The <conio.h> header is deprecated, meaning it is no longer part of the standard, so anything from there is implementation defined and may not work as you expect.
For why not to call system, it creates an annoying security issue. Here is an article about it: http://www.cplusplus.com/articles/j3wTURfi/
