Readability: C Programs are easy to read.
Maintainability: C Programs are easy to maintain.
Portability: C Programs are portable across different computer platforms by just recompile them according to the relative operating systems.
Learnability : You don’t have to remember many C keywords or commands before you start to write programming in C.
Major parts of popular operating systems like Windows, UNIX, Linux is still written in C.
