The printf() Family of Functions
All functions are declared in
int printf(char *format, ...);
– Print the additional arguments under control of the argument string to stdout
– Returns number of characters printed, or any negative number on error
int fprintf(FILE *stream, char *format, ...);
– As printf(), but print to the designated output stream
int sprintf(char *s, char *format, ...);
– Instead of actually printing anything, sprintf() will store the output characters
in the character array s points to
– The string will be \0 terminated
– It is the responsibility of the programmer to make sure *s is big enough
– The returned count of characters does not include the terminating nul character
(i.e. it is the same value that printf() would return)
