sscanf - Converts formatted input given by a string
The sscanf functions interpret character string according to a format, and returns the converted results.
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.
