byte length

1: "Byte" is byte, "bit" is bit;2:1 byte = 8 bit;Char is 2 bytes in Java. Java uses unicode,2 bytes (16 bits) to represent one character.ButString str = "compilation";byte[] bytes = Str.getbytes (); I wonder why it takes 3 bytes here?3 byte is 3*8=24

In the OC language, the NSString type of string, depending on the English alphabet and Chinese characters, is a length (String.Length a Chinese character as a length), whereas in fact an English letter occupies only 1 bytes and one Chinese character

During database insertion, if you use the insert statement to insert content to a varchar field, an error is reported because the length of the inserted content exceeds the specified length. In particular, when inserting a mix of Chinese and English

I encountered a small detail problem today and found it to be a long time. String STR = "a.2104697aa (Wuhu jinaorui) B .2104697ba (Changsha Bosch )"; Str. Length = 40 In C #, the length of string STR is 40. Here it refers to the length of string.

The code, connection information, and annotations in the ELF file are stored in sections (section) and contain a Header table (section header). For each section, there is a table entry in the section Header table (section Header table

Just to remember that strlen () return the number of characters of a string. often the strlen () function is used to compute the length in bytes of a string. this is correct until string is single byte encoded. if multi-byte char-set is used this

When a web application displays a string in a browser, due to the display length limitation, it is often necessary to intercept the string before display. However, many popular languages, such as C # and Java, use Unicode 16 (ucs2) encoding

Write a function that intercepts the string, input as a string and byte number, and output as a byte-truncated string. But to ensure that the Chinese character is not truncated half, such as "I abc" 4, should be truncated to "I ab", input "my

Check to see if the form meets the specified length. The maximum allowable n characters (2 digits in Chinese)! Copy Code code as follows: function Fucchecklength (strtemp) { var i,sum; sum=0; for (i=0;iif ((Strtemp.charcodeat (i) >=0) &&

　　 * * * string.valueof (Arr[i]). Matches ("[\u4e00-\u9fa5]") is only kanji * string.valueof (arr[i)). Matches ("[^x00-xff] 　　　　　　　　　　　 ") Double-byte (including Chinese characters) */public static string Getstrbylength (String str, int len) {if

The Java data has a byte (byte) short int long Short is two bytes, which equals 2 byte. An int equals two short and is equal to 4 byte. A long is equal to two int, or equal to 8 byte. Since computer numbers are 2-in-binary relationships, they are

Concept of struct type: A struct is a collection of data that contains a single number. The C language provides a structured data type as a collection to handle this complex data, and a struct can combine multiple single information together as a
