what does the symbol " -> " mean in KEIL MDK? RCC->AHBENR |= RCC_AHBENR_GPIOAEN;
also list of all syntax symbols used in KEIL MDK. I am trying to do one project in ARM Cortex M0(STM32F0 R8). please help me.
"We can also have pointer to a single structure variable, but it is mostly (sic) used with array of structure variables."
No - I don't think it's true at all to say that structure pointers are mostly used with arrays of structure variables.
Note that the claim wasn't about structure pointers but about pointers in generals.
Anyway - I often use pointers to a single object (integer, struct, ...) if programming in C. Often "updated" to references if programming in C++ to signify that it's 100% the caller that must guarantee that the address is valid.
Irrelevant. Unless the author has accumulated statistics on how people use a pointer, he/she can only voice his/her opinion.
The way Per Westermark chooses to use uses them is also not a guide to how other programmers use them.
My comment was just that Andy's response wasn't fully matching the quoted claim.
And I have made zero attempt to quantify if pointers are mostly used with arrays or with single objects - I just noted that I often use them for other things than arrays. And that statement alone is enough to show that a claim that pointers are mostly used for arrays of structures shouldn't be seen as a general truth.
The claim was about structure pointers - if moving to pointers in general, then a very significant percent will be related to C string manipulation or similar. But that's a different debate.
And I didn't say you did.
