Name cscanf - performs formatted input from console
Usage int cscanf(char *format[,argument, ...]);
Prototype in conio.h
Description cscanf, as all ...scanf family functions, scans input
fields, one character at a time, and converts them
according to a given format; these functions all:
. accept a format string that determines how the input
fields are to be interpreted.
. apply the format string to a variable number of input
fields in order to format the input
. store the formatted input in the addresses given as
arguments after the format string.
Return value cscanf returns the number of input fields successfully
scanned, converted and stored. If cscanf attempts to read
an end-of-file, the return value is EOF. If no fields were
stored, the return value is 0.
