Let’s walk through the steps to create a simple C++ program that will calculate a circle’s area using the formula area = pi x r2 First we’ll set up our preprocessor directives, and an empty main function. Next we will need to define variables that will be used by the program. In C/C++ we must…
Most of the time, if you ask someone how a web browser works, they will say it is used to display a web page. A slightly more technical answer might be, it downloads a web page and associated files, and displays it based upon the HTML codes. While this is correct, it is correct only…
A web page is made up of tags, which help tell the browser how to display a webpage. Within a tag, you may have attributes which provide some additional information to help display the webpage better. Tags Tags are used to define the elements within a web page. Tags are enclosed within angle brackets, <…
Writing the Document A web page is written as a plain text file. That means you can write it with a text editor such as Notepad, Notepad++, etc. You do not need a special web page builder or tool to create pages. Those can make it a little easier, but often cost a lot more…
Now the idea behind weighted search is nice, but it is complicated, requires several extra calculation steps, and can cause other issues. In a Database, you might have heard about indexing. The idea of finding a way to store a subset of your table which means faster searching. Of course, if you are looking through…
When working with a very large list of items, you might want to use a weighted search. One where instead of jumping to the middle, you try to get closer to your choice. Consider you had list with values between 1 and 10,000,000, and you were looking for an item with a value of 8,536,324….
If our data is presorted then a binary search starts to make a lot of sense. It is like the guessing game we mentioned earlier where you need to find a number between 1 and 100. No one asks for 1 then 2 then 3… until they find it. Instead we ask for the mid…
A brute force method of searching is slow and inefficient from a run-time perspective. However, it is relatively fast to write. With a brute force search, you scan through every item in a list until you find the element. As you can imagine, scanning through every item can be a time consuming process, especially if…
