Calling a function has a performance penalty because you have to create variables, specify scope, pause the current variables and push data onto the call stack, just to name a few reasons. C++ allows you to define an inline function, which should be short, to improve the performance. In doing so, the compiler will actually…
The next thing one should know about when working with the size of an element is margins, padding, and width. Margins Margins are simply the space between two elements. We can specify the margin to be the same all the way around an element, the same on the left and right and a different value…
In order to bring in the space between the edge of one element (the browser for example) and another, we have to understand sizing. All sizing is done through a series of unit measurements. Depending upon what you are creating will depend upon what unit you are wanting to choose. Some units are based upon…
There are two basic places you can define styles. There are legitimate reasons for both of them, and they should be used accordingly. In both cases, styles defined first may be overwritten with subsequent style definitions. It will only overwrite a value given to a property, not the whole style. So if you have a…
The process of Extract, Transform, and Load (ETL) is the process of taking data from one or more sources, and sending it to a different destination. During the process the data will be converted to fit the new destination locations. While ETL doesn’t get the attention of many other algorithms, it is a very important…
C++ has added the ability to have default arguments be defined when you declare your functions. To define a default value, you must specify the parameter name, and then assign it a value. If someone calls this function without passing an argument to the function, the computer will use 20 as the parameter. If they…
In previous examples, we’ve had to write our functions above the place where they are called. However, many developers like to place main as their first function they see, so it’s easier to find. Or they may not know the order that the function will be called. C and C++ allow you to define a…
Overloading a function means that you can create different functions with the same name, as long as their signatures are different. That means that the parameter list must be of a different number and/or data types from one to another. Overloading functions can make reading code much clearer/easier. This way functions that perform the same…
