I want to be fluent at c programming to start Embedded sytem
I'm glad for you.
What's a sytem?
This program will make your computer loopy!
void main(){for(;;);}
The best path to learn c is on a unix/linux console based platform (like BBB and RPi) and once you've become proficient at that then migrate to embedded systems.
C programming with embedded systems is more complex because you will need to deal with hardware specific details and be quite #pragma tic.
With MSP43x you'd be dealing with statements like;
SIMCO &= ~0x07;
With AVR programming;
#pragma interrupt_handler isr_t1:iv_TIMER1_COMPA
With PSOC programming;
saved->clkSelectReg & CY_SYS_CLK_SELECT_DIRECT_SEL_MASK) != CY_SYS_CLK_HFCLK_IMO
All of which are hardware specific and make no real sense to the learner.
If you plan to play with Arduinos then download and play with PROCESSING on your PC. It's where the Arduino IDE was spawned.
Processing was designed to make C programming easy for quick results for Arts Students.
Enjoy!
Sorry but I'm with Enrico with this - start on simple embedded boards.
I would recommend a ARM Cortex based part, probably one of the ST Nucleo boards but the TI Launchpads are good too.
If you want to learn C for embedded stuff then keep away from Linux targets for now.
Compact is being a bit naughty with his examples which are chosen to look obscure:
SIMCO &= ~0x07;
can be written like this:
foo_register = foo_register & 0xf8;
and what the line of code is doing is clearing bits 2 down to 0 in the register. (SIMCO or foo_register are just names for a variable which has been set up to be in the memory location of a control register in the processor).
The best book, not only about C, but the best programming language manual ever is "The C programming Language" (this is only an opinion 
).
You'll still need some tutorial stuff to go with your chosen board but if you stick with TI or ST you'll be OK.
