In which language is Linux written? What does the language have to do with the success of Linux?

What will be an ideal response?

Most of Linux is written in the C programming language. When written in

a portable style, C programs can be moved from one platform (processor-
or CPU-based system) to another by simply recompiling the code. Portabil-
ity means that manufacturers have a ready supply of software, operating

systems, and applications when they modify an existing platform or develop
a new one.
