Input

• int fgetc(FILE *) reads and returns a single character from the passed file. If there are no more characters to be read from the file, fgetc returns the special value EOF.

• We have already seen another useful file input function, fgets(char *string, int len, FILE *). This reads from the file into the string until either the end of the line, the end of the file, or len-1 characters have been read -- whichever comes first. The string is always /0 terminated, for your protection.

• There is also fscanf(FILE *, char *format, ...) which is just as useful (or useless) as scanf. In fact, scanf is usually just implemented as fscanf(stdin, ... ).
