2) Major Parts of popular operating system like linux, window,unix are still written in C. If you want to learn embedded system and wants to programm for the new devices available in market then you must go for learning of C because device drivers are mainly written in C.
3)All the smart devices available avaiable in market have some operating system or firmware which is also written in c.
4)C is very efficient in writing program for the low memory devices.
A long list of other benefits of learning c is there.
Let’s start
Very good point of C language is that C language is very similar to C language so its very easy for us to learn it and implement programs of C according to our requirement.
We can divide learning of C in following steps
intro to variable,keywords,comstant etc.—->learn advance instructions like pointers,array,funtions etc.—>writing programms and practising it regularly.
