How to fix non-terminating loop?

[JProgrammer]

Hi guys,

I am continuing to work on my refresher project for my entry level C++ software engineer interview. I have ran into another snag however. I am creating a text based game and there is a do-while loop that is supposed to terminate when the player chooses one of three answers. However, the loop does not exit. I was wondering if you could tell me what is wrong with the code?

P.S. I would also appreciate your feedback as well on the WIP game and the code in general. I am a computer science graduate with 0 years of professional experience so try not to be too critical!

repeat if c is not either of {1,2,3} , you need && instead of ||

while (c != 1 && c != 2 && c != 3);///since you want all the 3 conditions to be true for it to loop again
