  2. C string handling - Wikipedia

    en.wikipedia.org/wiki/C_string_handling

    The length of a string is the number of code units before the zero code unit. [1] The memory occupied by a string is always one more code unit than the length, as space is needed to store the zero terminator. Generally, the term string means a string where the code unit is of type char, which is exactly 8 bits on all modern machines.

  3. Uncontrolled format string - Wikipedia

    en.wikipedia.org/wiki/Uncontrolled_format_string

    The second version simply prints a string to the screen, as the programmer intended. Both versions behave identically in the absence of format specifiers in the string, which makes it easy for the mistake to go unnoticed by the developer. Format bugs arise because C's argument passing conventions are not type-safe.

  4. Tiny C Compiler - Wikipedia

    en.wikipedia.org/wiki/Tiny_C_Compiler

    A test compared different C compilers by using them to compile the GNU C Compiler (GCC) itself, and then using the resulting compilers to compile GCC again. Compared to GCC 3.4.2, a TCC modified to compile GCC was able to compile the compiler ten times faster, but the resulting .exe it produced was 57% larger, and much slower, taking 2.2 times ...

  5. C standard library - Wikipedia

    en.wikipedia.org/wiki/C_standard_library

    More generally, Python 2.x specifies the built-in file objects as being “implemented using C's stdio package," [48] and frequent reference is made to C standard library behaviors; the available operations (open, read, write, etc.) are expected to have the same behavior as the corresponding C functions (fopen, fread, fwrite, etc.).

  6. C (programming language) - Wikipedia

    en.wikipedia.org/wiki/C_(programming_language)

    C program source text is free-form code. Semicolons terminate statements, while curly braces are used to group statements into blocks. The C language also exhibits the following characteristics: The language has a small, fixed number of keywords, including a full set of control flow primitives: if/else, for, do/while, while, and switch.

    The C preprocessor (CPP) is a text file processor that is used with C, C++ and other programming tools. The preprocessor provides for file inclusion (often header files ), macro expansion, conditional compilation , and line control.

  9. GNU Compiler Collection - Wikipedia

    en.wikipedia.org/wiki/GNU_Compiler_Collection

    Each source compilation generates a separate object file and link-time helper file. When the object files are linked, the compiler is executed again and uses the helper files to optimize code across the separately compiled object files. Plugins Plugins extend the GCC compiler directly. [69]
