/**************************
Formatted input:
scanf(format_string, pointer_args)

Example:
{ int a, *bp;
  char c[81];
  scanf("%d %d %s", &a, bp, c);  // read string of non-white-space into c
}

Unformatted input:
Reading a line into a character string in memory for further processing:
see read_line() below.

/*** k = read_line(S, n);
 S must be an array of at least n chars.  n must be nonnegative.
 Read a line of chars from stdin into S (and make it null terminated),
 but read at most n chars so as not to overflow S.
 Returns: actual number of chars put in string.  Thus,
 if k is returned, S[0]..S[k-1] is the string; S[k] is the null character.
