2013年11月25日 · size() is a method specified in java.util.Collection, which is then inherited by every data structure in the standard library. length is a field on any array (arrays are objects, you just don't see the class normally), and length() is a method on java.lang.String , which is just a thin wrapper on a char[] anyway.

2014年2月13日 · The minimum range for int forces the bit size to be at least 16 - even if the processor was "8-bit". A size like 64 bits is seen in specialized processors. Other values like 18, 24, 36, etc. have occurred on historic platforms or are at least theoretically possible. Modern coding rarely worries about non-power-of-2 int bit sizes.

2013年8月2日 · Try this one - Query: SELECT database_name = DB_NAME(database_id) , log_size_mb = CAST(SUM(CASE WHEN type_desc = 'LOG' THEN size END) * 8. / 1024 AS DECIMAL(8,2)) , row_size_mb = CAST(SUM(CASE WHEN type_desc = 'ROWS' THEN size END) * 8. / 1024 AS DECIMAL(8,2)) , total_size_mb = CAST(SUM(size) * 8. / 1024 AS DECIMAL(8,2)) FROM sys.master_files WITH(NOWAIT) WHERE database_id = DB_ID() -- for ...

template<class T, size_t N> constexpr size_t size(T (&)[N]) { return N; } This has the nice property of failing to compile for non-array types (Visual Studio has _countof which does this). The constexpr makes this a compile time expression so it doesn't have any drawbacks over the macro (at least none I know of).

2012年3月14日 · The only real difference here is the size. All of the int types here are signed integer values which have varying sizes. Int16: 2 bytes; Int32 and int: 4 bytes; Int64: 8 bytes; There is one small difference between Int64 and the rest. On a 32 bit platform assignments to an Int64 storage location are not guaranteed to be atomic. It is guaranteed ...

If you have one image in each md file, one handy way to control image size is: adding css style as follows: ## Who Invented JSON? `Douglas Crockford` Douglas Crockford originally specified the JSON format in the early 2000s. ![

2008年9月17日 · It is imho even better style to omit the parenthesis when taking the size of a variable. sizeof *p or sizeof (int). This makes it clear quickly if it applies to a type or variable. Likewise, it is also redundant to put parenthesis after return. It's not a function. –

In other words, if a menu/content section/whatever stops being usable at a certain size, design a breakpoint for that size, not for a specific device size. See Lyza Gardner's post on behavioral breakpoints , and also Zeldman's post about Ethan Marcotte and how responsive web design evolved from the initial idea.

2012年4月16日 · Well, the desktop alone can use almost any standard (Joey named most, if not all, of them) size. I find it works well to combine 16x16, 32x32, 48x48, and 256x256 (and maybe more sizes) into one .ico file. I use IcoFx, and it is super easy to create multi-size icons from one 256x256 image.
