* <FUNCTION DESCRIPTION>
* The scanf_s function is equivalent to fscanf_s with the argument stdin interposed before the arguments to scanf_s
* The scanf_s function reads data from the standard input stream stdin and
* writes the data into the location that's given by argument. Each argument
* must be a pointer to a variable of a type that corresponds to a type specifier
* in format. If copying occurs between strings that overlap, the behavior is
* undefined.
*
* <INPUT PARAMETERS>
* format Format control string.
* ... Optional arguments.
*
* <OUTPUT PARAMETERS>
* ... The converted value stored in user assigned address
*
* <RETURN VALUE>
* Returns the number of fields successfully converted and assigned;
* the return value does not include fields that were read but not assigned.
* A return value of 0 indicates that no fields were assigned.
* return -1 if an error occurs.
