Hey I'm having a problem with a loop in my code. It's a pretty long problem, but it is a travel expenses program. I'm creating a function that calculates the meal expenses for the user. I have to get a total for two days(first day and last day). When I try to get a running total it doesen't work.
The number ends up about 2 or 4 numbers off.I know it's a little sloppy but I'll clean all the spacing and stuff up later. Here Ya go:

if you test it out use 0600 for departure time and 0900 for military time.

Can somebody tell me why is it coming out wrong and direct me toward the correct way

That's a big ask.
My suggestion would be to run the program with extra cout lines to find where the problem is occurring then post the smaller piece of code(that isn't working) for people to help you with.
There are some here who may slog through ~250 lines, but not many and not often.
