Use and importance of programming languages?

Answer 1

Answer If it weren't for computer languages where would we be today. Can you imagine writing a program as simply as writing a sentence instead of using computer language, it would be impossible. CD/delete means one thing, CD:/change direction and if the double dots aren't there the computer won't recognise the command. That's why so many people especially Computer Programmers spend years in Schools learning computer language so that the every day joe can't do their jobs.

Answer 2

Without programming languages, we would have to program computers using their native code, called machine code. This is nothing more than a series of binary digits (bits), where the particular bits within the code tell the processor which instruction you would like to execute.

Programming languages make programming faster and easier. It is faster because most languages make complex tasks, such as printing text to the screen, take up far less time to program. It makes programming easier by allowing the developer to write in a language comfortable to humans.

Instead of writing something like:

0A2BCDAD143900983AA9

You could use the far easier:

print "Hello World"

Also note that the example code (the pseudo machine code) would probably be many times bigger than the example above; even a simple task of writing to a screen requires quite a bit of machine code, especially if you were writing your own operating system.

Answer 3

A programming language is basically instructions given to a computer, written in human readable form.
