JavaScript Object Notation, or JSON, is a solution to the problem of how do we move data between systems, especially data between a server and a web client. JSON is an open-standards, data interchange format that uses a serializable string of data to store information. It was initiated in the early 2000’s by Douglas Crockford,…
A constant pointer means that the memory location will not change, not that the value at that memory location will not change. Consider the following code. What do you think will happen? Using const will make sure you always point to the right place. Using const with Pointers in C++ was originally found on Access…
OK, defining a new Datatype might be a bit of a stretch…how about, defining aliases? You can use the typedef keyword to define a new aliase for an existing data type in C++. The general form is: Let’s say you have experience with another language and you want to use a datatype name that they…
A Pointer variable, just called a pointer, holds the memory address of data that is stored. Through the pointer, you can read the address, and thus indirectly access the value of the variable. To access a value, you use the dereference operators (*) to get the value stored at that memory address. To store a…
There are several types of reviews a software company might use. Using one does not prevent you from using others – in fact, the best process is to use a combination of all of them. Informal to catch easy things early on, and ensure compliance with design specifications, formal to more rigidly test and verify,…
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…
