  2. printf - Wikipedia

    en.wikipedia.org/wiki/Printf

    printf is a C standard library function that formats text and writes it to standard output. The name, printf is short for print formatted where print refers to output to a printer although the functions are not limited to printer output. The standard library provides many other similar functions that form a family of printf-like functions.

  3. Uncontrolled format string - Wikipedia

    en.wikipedia.org/wiki/Uncontrolled_format_string

    Format bugs arise because C's argument passing conventions are not type-safe. In particular, the varargs mechanism allows functions to accept any number of arguments (e.g. printf) by "popping" as many arguments off the call stack as they wish, trusting the early arguments to indicate how many additional arguments are to be popped, and of what ...

    printf(string format, items-to-format) It can take one or more arguments, where the first argument is a string to be written. This string can contain special formatting codes which are replaced by items from the remainder of the arguments. For example, an integer can be printed using the "%d" formatting code, e.g.: printf("%d", 42);

  5. Format (Common Lisp) - Wikipedia

    en.wikipedia.org/wiki/Format_(Common_Lisp)

    Format is a function in Common Lisp that can produce formatted text using a format string similar to the print format string.It provides more functionality than print, allowing the user to output numbers in various formats (including, for instance: hex, binary, octal, roman numerals, and English), apply certain format specifiers only under certain conditions, iterate over data structures ...

  6. Indentation style - Wikipedia

    en.wikipedia.org/wiki/Indentation_style

    Stroustrup does not indent the labels public: and private:. Also, in this style, while the opening brace of a function starts on a new line, the opening brace of a class is on the same line as the class name. Stroustrup allows writing short functions all on one line. Stroustrup style is a named indentation style available in the editor Emacs.

  7. printf (Unix) - Wikipedia

    en.wikipedia.org/wiki/Printf_(Unix)

    In Unix and Unix-like operating systems, printf is a shell builtin (and utility program [2]) that formats and outputs text like the same-named C function. Originally named for outputting to a printer, it actually outputs to standard output. [3] The command accepts a format string, which specifies how to format values, and a list of values.

  8. scanf - Wikipedia

    en.wikipedia.org/wiki/Scanf

    The formatting placeholders in scanf are more or less the same as that in printf, its reverse function.As in printf, the POSIX extension n$ is defined. [2]There are rarely constants (i.e., characters that are not formatting placeholders) in a format string, mainly because a program is usually not designed to read known data, although scanf does accept these if explicitly specified.

  9. Criticism of C++ - Wikipedia

    en.wikipedia.org/wiki/Criticism_of_C++

    C++ string literals, like those of C, do not consider the character encoding of the text within them: they are merely a sequence of bytes, and the C++ string class follows the same principle. Although source code can (since C++11) request an encoding for a literal, the compiler does not attempt to validate that the chosen encoding of the source ...
