See your operating system doesn't just analyze the internal code of a file and and try to figure out what it is that would be an inefficient and inexact process instead whichever program created the file will slap an extension onto the end to tell the os exactly what kind of data is inside for example if you've ever saved a document in word you've probably seen that drop down menu that lets you pick exactly what format you want the file to be saved in after you make your choice word will attach the appropriate extension so that windows will know to use word if you've saved it as a standard word document, notepad if it's plain text or adobe reader if it's a pdf.

Why You Should Learn To Code - Is a Software Developer Career Worth It?

How much do you guys think a programmer makes? Imagine you were trying to build a video game and you wanted to put it on an interactive website. Using programming, you could build your very own game that nobody has built in the very specific way that you want it built, and you could put it on your very own interactive, fun website.
