I cannot figure out where a running total works for my program (new to coding / c++ )

total of what? on line 121, as an example, you can have runtot+= totalprice; where runtot would be a new variable initialized to zero (above the loop!) and maybe printed on 125 or whatever.

the running total of the user's price, in case they want another order of pizza when the program loops, I don't know how to implement that.


I will try what you recommended, thank you
