Front-end programmers work on things like graphical user interfaces (GUIs) and things that users interact with. Popular languages for front-end programmers include HTML, CSS, and Javascript. Back-end programmers work on things like databases, scripting, and program architecture, and things that go on behind the scenes. Popular programming languages for back-end users include Ruby, Python, PHP, and tools like MySQL and Oracle.
Variable: Variables are pieces of information that are stored so they can be recalled later. The variable is usually given a symbolic name. One example of a variable is if a program asks the user to input their name. The name they enter can be stored under an object symbol called “name”. The programmer can then use the “name” symbol to recall the name the user input and refer to the user by their name. A variable or object that consists of characters is called a “String”. [1] X Research source Control Structure: Control Structure tells the program which part of the program needs to be run and in what order. One common type of control structure is often referred to as an If/Then/Else statement. This tells the program that if a condition is true, then go run section the next section of the program. For all else, return to a different section. For example, if a program asks the user to create a password, the password is stored as a string. The password screen asks the user to input their password. An IF/Then/Else statement is used to tell the program that if the password entered is equal to the saved password, then execute the rest of the program. For all else, display “Your password is incorrect”. [2] X Research source Data Structure: Data structure is just a way of storing and organizing data so that it can be used efficiently. One example of a data structure is the contacts on your phone. Instead of storing your contacts each as separate variables, your programming can create one variable called a “List” which stores all your contacts. Syntax: Syntax is the correct way code is entered in a particular language. Each programming language has a different syntax. The syntax could be how to store variables, when to use different symbols (i. e parenthesis (), or brackets []), proper use of indentation, and more. If the syntax is not entered properly, the program will not be able to read the code and you will most likely get an error message. Tools: Tools are things that help make programming easier. These can be software features that check your code and make sure it’s correct. It can also be a pre-made program features that you can implement into your own program so you don’t have to build it yourself.
Python: Python is a good language for beginners to start with. It’s general-purpose language that allows you to do just about anything, and it’s easy to use. Ruby: Ruby is another good language for beginners to start with. Like Python, it is also a general-purpose, object-oriented language that is easy to learn. Java: Java is a popular language that has been around for years and continues to grow. It is the primary language used to develop apps for Android phones. It can also be used to develop computer programs. For example, Minecraft was originally built in Java. C: C was originally designed for writing system software. It’s embedded in just about every microprocessor today. There’s not a whole lot too it, but if you can learn C, you’ll have a solid foundation that allows you to learn just about any other programming language. C++: C++ is one of the most widely used multipurpose languages. It is one more difficult languages to learn, but it’s worth it. C++ gives you wider control over the applications you develop and gives you greater control over the computer’s hardware. It’s considered one of the best languages for developing large-scale applications. C#: C# (pronounced C sharp) is a little newer than C++ and has some added features. It’s a little easier to learn than C++, and it’s used in a lot of Windows applications. Swift: Swift is a multipurpose language developed by Apple. It is primarily used to develop apps for Apple products like iPhone, iPad, macOS, Apple TV, and more. [5] X Research source HTML/CSS. HTML and CSS are used in web design. HTML is used to create web pages that can be rendered by your web browser. You can use HTML to add objects to a web page and design the look of a web page. CSS is used to create a standard look or style across multiple web pages. For example, if you want to create a similar look and style across multiple web pages for a website, you can apply the same HTML style codes to each web page, or you can create a single CSS file that applies the same look to all web pages. Javascript: Javascript (not to be confused with Java) is another language used in web design. Javascript is used to create interactive features for a website. It is essential for designing any web application. PHP and MySQL: PHP and MySQL are back-end languages that manage databases on a server. Anytime a program, website, or apps store user information and require users to log in, that information is stored on a database. MySQL and PHP are languages that are used to create and manage databases.

Ruby: Download the latest version of Ruby [https://www. ruby-lang. org/en/downloads/ here}. Python: Many computer already come with Python installed, but you may need to install the latest version before you start programming in Python. Java: You will need to install Java Software Development Kit. In order to start programming in Java. PHP and MySQL: PHP and MySQL run on a server instead of computer. However, to develop and test PHP and MySQL locally on your computer, you will need to download and install server software such as Apache, as well as PHP itself. There are several software packages, including WAMP, and [[1]] that have everything you need in one program.
Eclipse. Netbeans. Visual Studio Code Android Studio (for Android apps). Xcode (for Mac, iPhone, and iPad apps).

Allow the user to organize a list of names and contact information. Display a text-based story that allows the user to choose their own path. Give the player a choice of attacks to choose from while the enemies generate their own random attacks. Calcuate the orbit of a planet around a star.
Contacts must be saved so they can be recalled at a later time. The story must account for previous choices the player made. The strength of the player’s attacks is determined by their current stats. The program should accurately calculate the orbit of the mass of any object the user inputs.
If you are reading code from instructions, reread the instructions and make sure you understand them. Ensure your code is organized, indented properly and is using the correct syntax. Check the spelling and make sure it is correct. [10] X Research source Use Print statements to check variable values. If you’re not sure if a section of code is being run, use a Print Statement to see if it gets to that section. Check the error messages and Google them. Break your code into sections and run the individual sections to isolate where a problem is. Trying searching for working code on the internet that does what you want to do. See if there’s a tool that does what you want. Enter code by hand instead of copying and pasting. Take a break and come back to the code. Ask for help. [11] X Research source
