scanf converts formatted input on standard input

## Syntax

    [v_1, ..., v_n] = scanf(format);

## Arguments

format

  a character string: specifies the format conversion.

v_1, ..., v_n

  converted results.

## Description

The `scanf` function gets character data on standard input (`%io(1)`), interprets it according to a `format`, and returns the converted results `v_1`, ..., `v_n`.

The `format` parameter contains conversion specifications used to interpret the input.

The `format` parameter can contain white-space characters (blanks, tabs, newline, or formfeed) that, except in the following two cases, read the input up to the next nonwhite-space character. Unless there is a match in the control string, trailing white-space (including a newline character) is not read.

- Any character except `%` (percent sign), which must match the next character of the input stream.

- A conversion specification that directs the conversion of the next input field. See scanf_conversion for details.
