C++ provides many useful math function inside the cmath header. As with Python, in C/C++, a function is a collection of statements which can perform a task with a single call, instead of having to write them all out. We’ll look at how to create our own functions later on. Trigonometric Functions Function Description sin(radians)…
Software doesn’t write itself, yet, and despite some people’s attempts. Therefore any process model needs to consider the individuals and teams that will be working on the project. The company must be willing and able to adapt and adopt a process model mindset if they are going to be successful. If they do not, they…
The Unified Process (UP) builds upon the classic processes and tries to incorporate the best parts of agile frameworks at the same time. UML – Unified Modeling Language, contains a robust methodology for modeling an object oriented system. UML is used throughout Part 2 of the book Phases of the Unified Process Similar to the…
Specialize Process Models may take on one more characteristics of the previous models, however they are applied when a specialized software engineering approach is chosen. Component Based Development This model is similar to the spiral model in that it is evolutionary in nature, however some of the step specifics vary. Formal Methods Model Formal methods…
Prescriptive Process Models strive for structure and order in software development. They tend to occur sequentially with defined guidelines, however they may not be the most effective for changing systems. Waterfall The waterfall method, sometimes called the classic life cycle, is one of the best known prescriptive process models. Each step move you forward and…
A switch statement executes statements based upon the value of a variable. It is useful to replace a series of if statements, if the if statements are all looking for an equality value. The general form of this is below: Your variable must be an integer value, and must be enclosed in parentheses. The case…
If you want to do more complex decisions in C++ there are a couple of ways to accomplish this. We’ll look at three that are fairly common. Nested If Statements Inside of an if statement true block, or the else block for that matter, you can nest another if statement. This allows you to build…
C/C++ has a couple of different ways to perform selections. We’re going to start looking at some of these. As with most languages, C./C++ has a Boolean data type, called bool. This can be used directly with your conditions, or separately to store data. Relational Operators Since we will need to compare values, C/C++ gives…
