We’ve mentioned that you pass values to a function. This is mostly true. When you pass a hard coded value as your argument, you always pass the value. See the example below. If you pass a primitive data type (int, float, long, double, char, bool – just to name a few examples), you pass by…
You will find defining a function in C++ very similar to defining a function in Python. There are some differences however. Let’s look at the general form, and then define the sections from here. Functions must be defined outside of other functions. C/C++ doesn’t have the concept of a sub or inner function like some…
There are times and cases when a use case using simple text, cannot properly describe a process. In those cases, look to supplement the Use Case to make it easier to understand the process. Activity diagrams can be used to show the workflow of a process the the user/system should take. A Swimlane diagram can…
A successful software product can be measured in many different ways (accuracy, speed, etc) however user satisfaction is often at the top of the list. A use case should properly describe how a user is going to use the system, so that it can be easily modeled and built – so that the users are…
Chapter 9 will focus on scenario bases modeling. Throughout analysis modeling, your focus should be on what, not how. While everything may not be known, we can approach this in an iterative method refining the model until everything is uncovered. The requirements model should have 3 primary objectives: Elements of an analysis modeling: Requirements Analysis…
Each requirement, when modeled, should be examined for: inconsistency, omissions, and ambiguity. You also need to check for: Requirements negotiation is often used to help ensure that requirements are reasonable, and can be met in a reasonable amount of time. You should look to a win-win situation, not a winner takes all contest. Validating Requirements…
We’ve seen the break in a switch statement. It stops running the blocks of code, and simple exits out of the switch. In the same manner, if you use a break in a loop, it exits us from the loop prematurely (not by the loop condition). The continue keyword, moves us to the end of…
The for loop is the counting loop of C++. It is usually designed to run a specific number of times, and then end. With it, it keeps a counter, to let you know where in the loop you are – useful when looping through an array which will look at soon enough. The general form…
