Simple C++ List Class

Published on August 18, 2009 in C/C++. Closed Tags: , , , , , , , , , , , , , , , , , .

Just as I published some days ago the Simple C++ String Class as a C++ learning exercise, now I am freeing a Simple C++ List Class.

The standard library has a list class. But, while learning, it’s a good idea to know how to develop your own list class.

That’s why I made the List class. It’s not intended for professional projects (for them, you should use the standard library’s list), but as help to learn C++.

Every C++ programmer knows that the standard library has a string class. But, while learning, it’s a good idea to know how to develop your own string class.

Attendance Control (wxWidgets Version)

Published on August 1, 2009 in wxWidgets. Closed Tags: , , , , , , , , , , , , , , .

wxAttendanceControl is a GUI version of Attendance Control.

It’s been prepared as a further introduction exercise to the wxWidgets GUI (Graphical User Interface) usage (the basic introduction exercise was the Celsius to Fahrenheit application).

For the complete exercise explanation please visit the original Attendance Control exercise.

If you just want to convert temperatures by using a website, you should visit the online celsius to fahrenheit conversion tool. Otherwise, keep reading…

This is a very tiny and simple application I’ve written to teach the basic usage of wxWidgets as an introduction to GUI (Graphical User Interfaces).

Its purpose is just what it’s name says: converting from celsius degrees to fahrenheit degrees (and sideways).

Attendance Control

“Attendance Control” is a console application made as an exercise to integrate the different C++ concepts taught in class up to the middle of the year.

The main objective is to be able to develop a employee attendance control which records the times (and justifications, if corresponding) of each time the employees arrive, go to lunch, return from lunch and go back to home.
