Bookmark or Share- c - why is *pp[0] equal to **pp - Stack OverflowSo pp[0] points to the address of p, which is 0x2000, and by dereferencing I would expect to get the contents of address 0x2000 That's were your reasoning strays, but understandably so. In C, the right hand side of an assignment, or generally an evaluation of an lvalue (vulgo: variable), more precisely an lvalue-to-rvalue conversion, is already ...
- html - When to use <span> instead <p>? - Stack OverflowThe
tag is a paragraph, 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.
- %p Format specifier in c - Stack Overflow1. So to get the address of variable i the correct format will be: 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. %F expects a double, not a pointer, so your code is undefined behavior, as was the original code.
- Handling of non breaking space: <p> </p> vs. <p> </p>A non-breaking space is a special kind of whitespace character that isn't considered to be insignificant, so it can be used as content for a non-empty paragraph. Even if you consider CSS margins on paragraphs, since an "empty" paragraph has zero height, its vertical margins will collapse. This causes it to have no height and no margins, making ...
- c++ - Where is `%p` useful with printf? - Stack OverflowUnfortunately 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.
