So this is a string with a null terminator but we cannot tell if the string ends here or not. May be 0 has a meaning or 0 has a value in the Devanagri character set. So having a length which says its length is 3 is important. ...
If the length field takes more space than the null terminator, then storing the length will marginally increase the size of the string in memory. (Our examples assume the length is 4 bytes; in practice, it might be smaller.) However, storing the length simplifies several operations on strings...
128) When told to print no more than n bytes, snprintf guarantees that it creates a string of length no more than n-1, with a null terminator at the end of the string. 129) Now, even if the same code segment tries to access p before a value has been assigned to it and it has...
Further, some UTF encodings use the two bytes0xC0and0x80to encode another NULL, so the ASCII and Unicode0x00is left free as a terminator. 2.4. Speed and Efficiency of Zeroes The NULL character special functions are in part due to the importance of the zero (0) value in computing. ...
Each field will be terminated by the output terminator (see --eol). --eol (disable with --noeol) Terminate output entries with a platform-specific end-of-line sequence rather than a NULL. May be useful with --glob. By default, the terminator is NULL unless --eol is given or escaping...
The Null character using ASCII value: Note: When you run this program, it will display the Null character as a blank space since it has no visible representation. However, it is there, and it acts as the string terminator in C strings. ...

null “null"的含义和定义 A non-existent or empty value or set of values. Zero quantity of expressions; nothing. (computing) the ASCII or Unicode character (␀), represented by a zero value, that indicates no character and is sometimes used as a string terminator. (computing) the ...
assembly 在程序集中将4位输入转换为十六进制是反过来的!回车的ASCII码为13，换行符的ASCII码为10。
(computing) The null character; the ASCII or Unicode character (␀), represented by a zero value, which indicates no character and is sometimes used as a string terminator. Zero Having no measurable or otherwise determinable value. Null (computing) The attribute of an entity that has no va...
