People are the primary driving factor in any project, but especially software development. Managers will often say this, but their actions will sometimes prove otherwise. There are different roles that people will have, and they need to know what is expected of them, and be able to perform that task with the skill required. Unfortunately,…
Project management is said to focus on the 4 Ps. People, Product, Process, and Project. – And it should focus on that order. People Software development is an intensely People driven process. They have to design, model, develop, debug, and support the project. So without people you will not have a completed project. Often managers…
One of the cool things about object oriented programming is that you can derive a class from an existing class. this allows you to have most of the class built from an existing class, and not need to rewrite the whole class, only the new parts. Additionally, if the original class, called the base class…
We’ve seen how to overload an operator in C++. The stream operators are similar in nature, however, they can be a bit more involved. In many languages, there is a default toString() method for your classes, which lets the language know how to connect to the string. However, there isn’t one in C++, so we…
Regular Expressions, often called RegEx, is a sequence of characters that defines a search pattern to run against another string of data. This is often used to perform a find and replace or check for validation. Different languages apply regular expressions differently. The strictest use the full range of special characters and commands, while others…
We’ve already looked at styling rows within a table, however, you can style more. By default a table doesn’t have any borders, color, or anything else. Luckily, like all HTML elements, you can apply styles to your elements. And since a table is made up of a lot of elements, you can apply styles to…
C++ allows you to define functions for operators, this is called operator overloading. Now why would you need to do that? Well, consider the Circle class we defined earlier. Let’s say I needed to compare two circles to see which one was larger, normally I’d write something like: The problem is, C++ has know way…
Using arrays to store a collection of variables, even objects, if very beneficial. However, it does have some limitations given that arrays are of a fixed size, and cannot shrink or grow with use. This means you either run out of space after a set of time, or you waste a lot of space as…
