How to start coding program using c language?

I want to learn how to write a program in C language,. what are the things I must do? what are the information must I declare? How would I do register addressing? How should my sets of instructions be arranged? Thanks..

first take a good book in c programming and read it.
you will know about declaration etc.

you have asked for 'how to do register addressing?'
this is assembly level programming. dont mix it with C.

probably a 'basic/fortran' programmer ?

Hi,

First select what microcontroller (-family) you want to use.
Then buy a development board with this controller. It should be one with a lot of (example) software in the net..and with a lot of discussions. (Arduino is such a thing)
Maybe you need a power supply and a programmer.
Then start with some example programs you find in the net. Maybe a simple LED blink function.
With it you can see what important defines and setup you need.
Try to modify the code and see what happens

Learning by doing is a good way. With fast results.
But be warned: Not every code you find in the internet is "good code".
From the beginning: try to comment your code. Divide it in visible sections with headlines.

But for sure this can't a void a good book.

K&R c programming text is good one

** ALWAYS ** First step is defining what you want to achieve.

Writing code comes afterwards.

Programming should be 99% inspiration and 1% perspiration!
