Hi, I observed a strange behaviour (for me only) of void pointer. I wrote a code to access an integer through void pointer as below:
void *ptr; int a[2] = {1,2};
ptr = (int *)&a; ptr++; // This is giving error: Unknown Size
Why the above increment statement is giving error as i already cast the pointer to int type ?
Can anybody help me in understanding this ?

Do a 'C' programming course.
Get a decent 'C' textbook.
Probably best to learn the language on a PC or similar; then, once you know the language, you can learn how to apply it to microntrollers...
Thanks Neil for your suggestion. I know the basic of C, but some miscellaneous concept like void pointer, null pointer, dangling pointer,etc.. will be explored in most of the book. Generally C book gives the basic programming guide, not the in depth knowledge. Or may be but i am not aware of such book.
If any one have idea then please let me know.

ANDY, that was a nice answer, applauds, is there a reason to learn C, and THEn apply to ucontrollers,
certainly there should be other ways,
andy, do u take classes for C? got to start from 'c'ing c..
is there a reason to learn C, and THEn apply to ucontrollers, certainly there should be other ways,
There are as many 'ways' as there are peaches in Gaffney, but "to learn C, and THEn apply to ucontrollers" is the best and - surprise - fastest.
