When using VC to do development, for some strings, will often call General _t, _t, T (), in fact, these things are related to Unicode. For example, AfxMessageBox (_t ("error! Fail to connect the database! ")); Here a _t () is used, and no _t () is

The following is the basics of character, Byte, and encoding format:Http://www.regexlab.com/zh/encoding.htmThe program involves several conversions of the encoded format:1. Code text, string is saved according to the encoding method set by our text2.

Today to do the curriculum design encountered with the database interaction, the SQLite database is set to UTF-8 format encoding, inserted into the database is correct, but when read out of the error, the reason is that Python str default is ASCII

We know that the C language uses the char data type to represent a 8-bit ANSI character, and by default when a string is declared in code, the C compiler converts the characters in the string into an array of 8-bit char data types:// An 8-bit

Description: The C language is not defined for string types, but there are many library functions about strings (such as: strstr (matching substrings in the original string), strcpy (copying the contents of the original string to the target string),

Question one: Find out if two strings of string have the same character.　　Idea one: Similar to two sets to find the same elements, a set as a benchmark to facilitate two sets, encountered the same element is interrupted, the time cost is O (N2)

When we write the program, the most used is the processing of the string, and the conversion between ANSI and Unicode often make us dizzy eye disorder.It should be said that Unicode is a good way to encode, in our program should try to use Unicode
