  2. Null-terminated string - Wikipedia

    en.wikipedia.org/wiki/Null-terminated_string

    Null-terminated strings require that the encoding does not use a zero byte (0x00) anywhere; therefore it is not possible to store every possible ASCII or UTF-8 string. [ 8 ] [ 9 ] [ 10 ] However, it is common to store the subset of ASCII or UTF-8 – every character except NUL – in null-terminated strings.

  3. C string handling - Wikipedia

    en.wikipedia.org/wiki/C_string_handling

    For character strings, the standard library uses the convention that strings are null-terminated: a string of n characters is represented as an array of n + 1 elements, the last of which is a "NUL character" with numeric value 0.

  4. Null character - Wikipedia

    en.wikipedia.org/wiki/Null_character

    The ability to represent a null character does not always mean the resulting string will be correctly interpreted, as many programs will consider the null to be the end of the string. Thus the ability to type it (in case of unchecked user input) creates a vulnerability known as null byte injection and can lead to security exploits. [10]

  5. C string - Wikipedia

    en.wikipedia.org/wiki/C_string

    Null-terminated string, known as a C string or C-style string due to it's use by the C programming language; C string handling, C functions to work with null-terminated strings; C-string (clothing), a specific type of thong, or a brand of women shorts; C string (music), one of the strings on various instruments, for example the lowest string on ...

  6. String (computer science) - Wikipedia

    en.wikipedia.org/wiki/String_(computer_science)

    In terminated strings, the terminating code is not an allowable character in any string. Strings with length field do not have this limitation and can also store arbitrary binary data. An example of a null-terminated string stored in a 10-byte buffer, along with its ASCII (or more modern UTF-8) representation as 8-bit hexadecimal numbers is:

  7. C syntax - Wikipedia

    en.wikipedia.org/wiki/C_syntax

    There are several standard library functions for operating with string data (not necessarily constant) organized as array of char using this null-terminated format; see below. C's string-literal syntax has been very influential, and has made its way into many other languages, such as C++, Objective-C, Perl, Python, PHP, Java, JavaScript, C# ...

  8. strsafe.h - Wikipedia

    en.wikipedia.org/wiki/Strsafe.h

    The functions included in strsafe.h replace standard C string handling and I/O functions including printf, strlen, strcpy and strcat. [2] The strsafe functions require the length of the string in either characters or bytes as a parameter and if an operation would exceed the length of the destination buffer, the operation fails and the string is still terminated with a null in its final valid ...

  9. Comparison of Pascal and C - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_Pascal_and_C

    C string literals are null-terminated; that is to say, a trailing null character as an end-of-string sentinel: const char * p ; p = "the rain in Spain" ; /* null-terminated */ Null-termination must be manually maintained for string variables stored in arrays (this is often partly handled by library routines).
