As with most languages, we always want to start with a “Hello World” program. Remember, this is to make sure everything is working, as much as it is to learn the programming language. For simplicity’s sake, we’re going to use the online editor: https://www.jdoodle.com/execute-ruby-online or https://www.onlinegdb.com/online_ruby_compiler You will notice right away that in Ruby, we…
Version 4 and prior of HTML was a little “wild west” in how it was interpreted and defined. It wasn’t always consistent in how it was implemented or interpreted, and sloppy interpreters allowed lots of pages with errors displayed things differently. At one point it was estimated that 98% of all web pages had at…
Standard convention for programming with C++ can be found in several other languages. Not only is the commands similar to other languages, but so is the structure format. Now C++ doesn’t care about white space (tabs, spaces, new line characters, etc), but it makes it easier to read and debug, and work with others. While…
C and C++ are complied languages. Unlike Python which is typically interpreted, which means the run time converts the source code to computer understandable code as it runs, C/C++ has to go through a process to make it run on a computer. This process is called compiling, but there is actually several steps to this…
A little bit of history C++ is an expansion of the C programming language. It’s main addition was the ability to create and use objects. That makes it an Object Oriented Programming (OOP) based language. You do not have to start with objects however, as it retains all of the C procedural language constructs and…
Let’s look at a simple program and work through it step by step. #include #include statements are at the top of the file, and let you include any libraries you might need. iostream, in our example is used to help process input and output. You might think this is standard, but if you are building…
Writing a class or two doesn’t seem to create that big of a problem, and for simple projects it’s not. However, this isn’t effective for large projects with dozens, if not hundreds, of Classes. That’s where packages come into play. A Java package is a way to both logically and physically organize your Java code….
Pseudo-code, is essentially “fake code”. Well if it’s fake, why should we use it? That is a good question, so let’s look at what it is used for, and isn’t. Flowcharts are often used to help define the flow of an algorithm. However, they often get long, and hard to manage, especially with larger and…
