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
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.
