Thread: help me im a C++ noobie!!!

hey hey hey

with the following code which is pretty simple, it works fine except for the line: item[5].grossF();

this in turn displays the gross of only item 5 which is basically just the items total...

i want it to add all the gross total together and then display the sum as the variable grossT?

any help will recieve copious amounts of sex in return!

thanks

I saw that you are printing the gross total of
the last Item in your array of structures.
Remember that you are using 5 different structs.
Try to run through all the structs and sum the gross totals
That is what you want.
