单字节转宽字节 :size_t mbstowcs( wchar_t *wcstr, const char *mbstr, size_t count ); 上面这两个是标准C++的,下面两个好像是微软的函数。不过上面两个函数只能一个一个的转换,也就是说一次只能转换一个字符。下面两个方法就是 宽字符串与单字节字符串之间的转换。 宽字节转多字节 :WideCharToMultiByte...
Does anyone know how to separate the individual bytes in an int? int is 4 bytes long and I want to take those bytes and put them into a char[4]. This code shows grabbing the data a byte at a time (and displaying is interpreted as a char - if you want numbers, you can cast it...
Strings contain Unicode characters. Their literals are written in single or double quotes : 'python', "data". Bytes and bytearray objects contain single bytes – the former is immutable while the latter is a mutable sequence. Bytes objects can be constructed the constructor, bytes(), and from...

BytesStore is a block of memory with fixed size into which you can write data and later read. You can create a BytesStore using the bytes in a CharSequence, String, ByteBuffer or another BytesStore. //Create a BytesStore bs using bytes in a String. This gives you a BytesStore with /...

PostgreSQL includes almost all SQL92 and SQL99 data types such as INTEGER, NUMERIC, BOOLEAN, CHAR, VARCHAR, DATE, INTERVAL, and TIMESTAMP, provides support for foreign keys, views, joins, triggers and stored procedures (in many different languages) and is ACID compliant. The program is also ...
