I think I have learned a much more but what is the use of c language and how?

Answer 1

//C has been used to write everything from operating systems (including Windows and many others) to complex programs like the Python interpreter, Git, Oracle database, and more.
The versatility of C is by design. It is a low-level language that relates closely to the way machines work while still being easy to learn.

Answer 2

One reason for all the different programming languages is to have different options for different needs. For example, as Shudarshan said, C is used to create other programming languages, which is much easier than writing a new language from machine language. Languages like javascript and php were created to make websites active and interactive. The different languages give a variety of options to choose from when writing a program.

Compare it to vehicles. I’d hate to try getting sheets of plywood home with a motorcycle, but they would go right inside a Ford E350 I used to own. People who drive an hour each way to work daily wouldn’t be able to afford the gas my big van would take, so they just have a small car.

Different vehicles, or programming languages, for different purposes.
