  2. Null-terminated string - Wikipedia

    en.wikipedia.org/wiki/Null-terminated_string

    In computer programming, a null-terminated string is a character string stored as an array containing the characters and terminated with a null character (a character with an internal value of zero, called "NUL" in this article, not same as the glyph zero).

  3. Null character - Wikipedia

    en.wikipedia.org/wiki/Null_character

    In all modern character sets, the null character has a code point value of zero. In most encodings, this is translated to a single code unit with a zero value. For instance, in UTF-8 it is a single zero byte. However, in Modified UTF-8 the null character is encoded as two bytes : 0xC0,0x80. This allows the byte with the value of zero, which is ...

  4. Flexible array member - Wikipedia

    en.wikipedia.org/wiki/Flexible_array_member

    The sizeof operator on such a struct gives the size of the structure as if the flexible array member were empty. This may include padding added to accommodate the flexible member; the compiler is also free to re-use such padding as part of the array itself.

  5. Whitespace character - Wikipedia

    en.wikipedia.org/wiki/Whitespace_character

    In computer character encodings, there is a normal general-purpose space (Unicode character U+0020) whose width will vary according to the design of the typeface. Typical values range from 1/5 em to 1/3 em (in digital typography an em is equal to the nominal size of the font, so for a 10-point font the space will probably be between 2 and 3.3 ...

  7. Input/output (C++) - Wikipedia

    en.wikipedia.org/wiki/Input/output_(C++)

    Bjarne Stroustrup, the creator of C++, wrote the first version of the stream I/O library in 1984, as a type-safe and extensible alternative to C's I/O library. [5] The library has undergone a number of enhancements since this early version, including the introduction of manipulators to control formatting, and templatization to allow its use with character types other than char.

  8. C string handling - Wikipedia

    en.wikipedia.org/wiki/C_string_handling

    Strings are passed to functions by passing a pointer to the first code unit. Since char * and wchar_t * are different types, the functions that process wide strings are different than the ones processing normal strings and have different names. String literals ("text" in the C source code) are converted to arrays during compilation. [2]

  9. Uninitialized variable - Wikipedia

    en.wikipedia.org/wiki/Uninitialized_variable

    Uninitialized variables are powerful bugs since they can be exploited to leak arbitrary memory or to achieve arbitrary memory overwrite or to gain code execution, depending on the case. When exploiting a software which utilizes address space layout randomization (ASLR), it is often required to know the base address of the software in memory.
