fputc, fputs, putc, putchar, puts - output of characters and strings
#include <stdio.h> int fputc(int c, FILE *stream); int fputs(const char *s, FILE *stream); int putc(int c, FILE *stream); int putchar(int c); int puts(const char *s);
fputc() writes the character
c, cast to an
unsigned char, to
fputs() writes the string
stream, without its terminating null byte ('\0').
putc() is equivalent to fputc() except that it may be implemented as a macro which evaluates
stream more than once.
c) is equivalent to putc(
puts() writes the string
s and a trailing newline to
Calls to the functions described here can be mixed with each other and with calls to other output functions from the
stdio library for the same output stream.

It is not advisable to mix calls to output functions from the
stdio library with low-level calls to write(2) for the file descriptor associated with the same output stream; the results will be undefined and very probably not what you want.
