C is a practical programming language or not?

Answer 1

It is practical to know, but not usually practical to use (except for a small percentage of programmers). If you can read C code you can basically read and understand any language code you’ll see, but coding with it is a long process and other languages that specialize in an area are typically better

Answer 2

Yes, ofcourse it is. All the modern programming languages are largery based on it.

Answer 3

Practical for embedded systems.
