C Programming Language:
C is such a powerful language that even to this date many applications (serious ones) are developed in this language. In fact this is one language which will probably never go out of fashion.
Embedded devices use C. Real time operating systems use C. Parts of some other operating systems, such as the linux kernel, are written in C. Some hardware drivers are written in C.
C is still used when an efficient and relatively low-level language is needed(when compared to Java or C #).
One consequence of C's wide availability and efficiency is that compilers, libraries, and interpreters of other programming languages are often implemented in C.
The primary implementations of Python (CPython), Perl 5, and PHP, node.js, are all written in C.
