C++ calling need help ASAP!!!!
So I am trying to figure out how to call line 41 to function on line 105 after you make your selection it should display Selection: name, price per unit: $price
I need to know how to do this so each time you select it to display this so, for example, hit 1 for water Selection: Water, price per unit: $1.45 then it should ask for quantity. i should ask display this each choice you make until you end the loop for the summary.
This shoud look like:

#include <iostream>
