Embedded C programming novice to professional in 24 hrs
Why C programming?
C is a small but powerful language. C has a powerful set of operators which allows the
programmer to access the machine at bit level. C is portable that means we can move source code written in one
machine to another machine. These popular features make C as the go to language while writing operating systems,
compilers, database programs, embedded systems and so on.
