Hi! I was thinking to create some PHP and HTML and CSS and maybe even Javascript tutorials... but I don't know if i can use the syntax of a programming language freely ... I don't know if it is protected by copyright! I read on Google that the programming language syntax or even the entire programming language can't be protected by copyright... What do u know? Is it legit to make tutorials about these languages and present code or fragments of code or just some elements such as tags, program instructions, mark words for variables and others such?
It's all free, the only thing that you would have to pay for is a fancy IDE (Intergrated Development Environment). But their are plenty of free ones around.
No, you can make tutorials without an IDE. IDE is just software. A development environment in which you can write code. As with every software - some are free and some propitiatory.
