Code structure is like this:
|
|
1. encrypt.cpp en /header/encrypt.h contain functions to hash passwords and
|
|
verify passwords
|
|
|
|
2. data.cpp and /header/data.h contain the code to start up the database.
|
|
Originally, they were supposed to contain all the functions to save to the
|
|
database and query from the database. I had trouble doing that, (cyclical
|
|
includes) and some other issues. the other issues are gone due to the latest
|
|
refactor, but to make it like my original plan is going to take a few hours, and
|
|
I have done too much already to want to do more work unless needed.
|
|
The functions to save to a database have been integrated in the classes
|
|
themself, and unless issues arrise from that I'm not changing that. Functions to
|
|
get objects from the database are in Query.cpp en header.
|
|
|
|
3. Park_time.cpp en header.
|
|
Contain the implementation details of Park_time, which is basically a record of
|
|
who parked at what spot and when. Uses a mix of ctime and chrono functions to do
|
|
most of the stuff, it's a mess. I will probably have to commit to Doing it one
|
|
way or the other to make it more comperhensible, especially for whoever will
|
|
make report functions.
|
|
|
|
4. Customer.cpp and header.
|
|
Contains the implementation of Customer. Customer represents a customer, and
|
|
saves park_time instances in itself. Not much to explain.
|
|
|
|
5. Park_spot.cpp and header.
|
|
It contians the implementation details of Park_spot, which represents it's
|
|
namesake.
|
|
|
|
6. Query.cpp and header.
|
|
Cointain functions that search the database and return objects(P_time, P_spot,
|
|
Customer) It is the least tested of the whole project, use with care.
|
|
|
|
Explanation of what members do of P_time, P_spot, Customer are in the respective
|
|
headers. Explanations of how the member functions work(Or how I intended for
|
|
them to work) are in the respective .cpp files. void Wait(int sec)

Why is this not in query.cpp? Because somehow, it errors out when it's there.

The error message indicates it is a memory issue but I suspect it's a

concurrency issue. Do not move this.
