html - When to use lt;p gt; vs. lt;br gt; - Stack Overflow 14 You want to use the <p> tag when you need to break up two streams of information into separate thoughts <p> Now is the time for all good men to come to the aid of their country < p> <p>The quick brown fox jumped over the lazy sleeping dog < p> The <br > tag is used as a forced line break within the text flow of the web page
html - When to use lt;span gt; instead lt;p gt;? - Stack Overflow The <p> tag is a p aragraph, and as such, it is a block element (as is, for instance, h1 and div), whereas span is an inline element (as, for instance, b and a) Block elements by default create some whitespace above and below themselves, and nothing can be aligned next to them, unless you set a float attribute to them Inline elements deal with spans of text inside a paragraph They typically
Why is the format of %p and %x different in a format string? No %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
xml - Regular expression \p {L} and \p {N} - Stack Overflow 280 \p{L} matches a single code point in the category "letter" \p{N} matches any kind of numeric character in any script Source: regular-expressions info If you're going to work with regular expressions a lot, I'd suggest bookmarking that site, it's very useful
%p Format specifier in c - Stack Overflow If this is what you are asking, %p and %Fp print out a pointer, specifically the address to which the pointer refers, and since it is printing out a part of your computer's architecture, it does so in Hexadecimal In C, you can cast between a pointer and an int, since a pointer is just a 32-bit or 64-bit number (depending on machine architecture) referring to the aforementioned chunk of memory
c - Why is *p++ different from *p += 1? - Stack Overflow The key is the precedence of the += and the ++ operator The ++ has a higher precedence than the += (in fact, assignment operators have the second lowest precedence in C), so the operation *p++ means dereference the pointer, then increment the pointer itself by 1 (as usually, according to the rules of pointer arithmetic, it's not necessarily one byte, but rather sizeof(*p) regarding the
c - What is the difference between *p and p*? - Stack Overflow The reason is partly due to the idea that in C, types should mimic how they work That is, if you have int *p; Then the syntax is a visual cue that to get to the integer pointed at by p, you should put a star in front of it
Whats P=NP?, and why is it such a famous question? The question of whether P=NP is perhaps the most famous in all of Computer Science What does it mean? And why is it so interesting? Oh, and for extra credit, please post a proof of the statement's
Difference between int* p and int *p declaration [duplicate] Summarily, int *p is better if your coding style code-base utilises multiple declarations on a single line of source code, otherwise int* p offers a clearer separation of type and the following identifier For all that, people's preferences are largely based on what they're used to
