%p Format specifier in c - Stack Overflow
2012年9月28日 · %p is for printing an address but you need to use the ampersand i.e. & operator before i to get the address of i. So to get the address of variable i the correct format will be: void main() { int i=85; printf("%p %Fp", &i, &i); getch(); } if you don't use & then u will just get the value contained in i which in this case is 85 or 55 in hex
c++ - Where is `%p` useful with printf? - Stack Overflow
2010年3月3日 · Unfortunately it prepends '0X' not '0x', making the actual value hard to read. Presumably this is due to a missing '%P' variant. All told, this format specifier suffers from the problem of all 'platform dependent' implementations, that you can't really control what you're going to get. I use '0x%p' at the risk of getting a double 0x0X at the start.

2015年1月5日 · What does /p stand for in set /p=? I know that / enables a switch, and I'm fairly sure that I know /a is for arithmetic. I've heard numerous rumours, some saying /p is for prompt, others stating it stands for print. The only reason I slightly doubt it is prompt is because in many cases it does not ask for a prompt, yet prints on the screen, such as
Why is the format of %p and %x different in a format string?
2015年2月25日 · %p expects the argument to be of type (void *) and prints out the address. Whereas %x converts an unsigned int to unsigned hexadecimal and prints out the result. And coming to what %p does is implementation defined but the standard just says that %p expects void* argument else the behavior is undefined.

What's "P=NP?", and why is it such a famous question?
P stands for polynomial time. NP stands for non-deterministic polynomial time. Definitions: Polynomial time means that the complexity of the algorithm is O(n^k), where n is the size of your data (e. g. number of elements in a list to be sorted), and k is a constant.
