- Pointer expressions: *ptr++, *++ptr and ++*ptr - Stack Overflow
*ptr++ *++ptr ++*ptr I have tried Ritchie But unfortunately was unable to follow what he told about these 3 operations I know they are all performed to increment the pointer the value pointed to I can also guess there may be a lot of things about precedence and order of evaluation Like one increments the pointer first then fetches the content of that pointer, one simply fetches the content
- C Pointers: *ptr vs ptr vs ptr - Stack Overflow
Suppose *ptr points to a variable What does *ptr, amp;ptr, and ptr each mean? Many times, I get confused between them Do anyone mind clarifying between those statements and give some concrete
- c - Pointer Arithmetic: ++*ptr or *ptr++? - Stack Overflow
In the context you described, you probably want to write ++*ptr, which would increment x indirectly through ptr Writing *ptr++ would be dangerous because it would march ptr forward past x, and since x isn't part of an array the pointer would be dangling somewhere in memory (perhaps on top of itself!) Hope this helps!
- What is the difference between int* ptr and int *ptr in C?
int* ptr; int *ptr; I think that in the declaration int* ptr;, ptr 's value cannot be changed whereas it can be changed for the declaration, int *ptr; I am not sure if that is it though What is the concept behind the two declarations?

- What is the difference between std::shared_ptr and std::atomic lt;std . . .
The atomic "thing" in shared_ptr is not the shared pointer itself, but the control block it points to meaning that as long as you don't mutate the shared_ptr across multiple threads, you are ok do note that copying a shared_ptr only mutates the control block, and not the shared_ptr itself
- x86 - In assembly, what does `PTR` stand for? - Stack Overflow
and dword ptr [ebp-4], 0 In assembly code like above, what does the term PTR stand for? I know their usage -- size directives; but where had the term PTR been coined from?
- What is the difference between char **ptr and char *ptr [] in C?
Character strings are always arrays, and arrays are generally always pointers, so the two are generally equivalent which means that **ptr = *ptr[] What you end up with is an array of an array of chars, or an array of strings
