Within the context of the software development, the terms defect and fault are synonymous. Both imply a problem that is discovered after the software has been released to end users. The book makes a distinction between error – a problem found before being released to the end user and defect or fault. However, in the real world,…
Traditional procedural programming focuses on actions – functions. Object oriented programming focuses on data (objects) and the operations on objects. You want to look at items that you will be coding, and think, what makes this information up? and, What things can it do, and/or be done to it? Objects in the physical realm are…
C++ has some interesting keywords that allow you to do different things. For example, if you want to make sure that you don’t accidentally change any values in a method, you can use the const keyword. Now this is similar to how you use it on a parameter for a function, but since you don’t…
Something that can happen in larger projects is that a header file for a class is included in multiple files. While this seems trivial, some compilers can run into a problem of thinking it’s multiple classes with the same name. Luckily, C++ gives us a method to prevent this from happening, by using a built…
Everything we’ve looked at so far is what is known as an instance member. That is, each instance of a class – called and object, has it’s own set of properties and methods. This is mostly what is done. So if we look at two Circle objects for example, the radius of one circle is…
Quality doesn’t happen by accident. It is an intentional process. So how do you obtain quality software? Using Software Engineering Methods – you need to have a reasonably complete understanding of the problem as well as a comprehensive design to be able to solve that problem. A project manager must use good project management skills…
The quality dilemma is basically two fold: The issue is how to find a proper middle ground where your first users don’t feel like beta testers, but can still afford the software and have it come out in time to beat your competitors. Therefore you must be able to build something that is “good enough”…
If you were to ask someone on the street, what is quality – do you think they could answer? What do you think they would answer? Would it be the same are yours? Quality is a fairly complex topic, that means different things to different people. It is something that can be recognized, even if…
