#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); int ungetc(int c, FILE *stream);
fputs() writes the string s to stream, without its trailing '\0'.
putc() is equivalent to fputc() except that it may be implemented as a macro which evaluates stream more than once.
putchar(c); is equivalent to putc(c,stdout).
puts() writes the string s and a trailing newline to stdout.
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.
puts() and fputs() return a non - negative number on success, or EOF on error.
