Defined in header
int puts( const char *str );
Writes every character from the null-terminated string
str and one additional newline character '\n' to the output stream
stdout, as if by repeatedly executing fputc.
The terminating null character from
str is not written.
|str||-||character string to be written|
 Return value
On success, returns a non-negative value
On failure, returns EOF and sets the error indicator (see ferror()) on
puts function appends the newline character to the output, while fputs function does not.
Different implementations return different non-negative numbers: some return the last character written, some return the number of characters written (or INT_MAX if the string was longer than that), some simply return a non-negative constant.
A typical cause of failure for
puts is running out of space on the file system, when stdout is redirected to a file.
