Printf functions (which stands for "print formatted") are a class of functions typically associated with some types of programming languages. They accept a string parameter called the format string, which specifies a method for rendering an arbitrary number of varied data type parameter(s) into a string. This string is then by default printed on the standard output stream, but variants exist that perform other tasks with the result. Characters in the format string are usually copied literally into the function's output, with the other parameters being rendered into the resulting text at points marked by format specifiers, which are typically introduced by a % character.
