int puts ( const char * str );
Write string to stdout
Writes the C string pointed by str to the standard output (stdout) and appends a newline character ('\n').
The function begins copying from the address specified (str) until it reaches the terminating null character ('\0'). This terminating null-character is not copied to the stream.
Notice that puts not only differs from fputs in that it uses stdout as destination, but it also appends a newline character at the end automatically (which fputs does not).
C string to be printed.
On success, a non-negative value is returned.
On error, the function returns EOF and sets the error indicator (ferror).
