std::puts(3)

NAME
std::puts - std::puts

Synopsis
   Defined in header <cstdio>
   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
   std::fputc.
   The terminating null character from str is not written.

Parameters
   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 std::ferror) on stdout.

Notes
   The std::puts function appends the newline character to the output, while std::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 std::puts is running out of space on the file system,
   when stdout is redirected to a file.

Example
// Run this code
 #include <cstdio>
 int main()
 {
     int rc = std::puts("Hello World");
     if (rc == EOF)
         std::perror("puts()"); // POSIX requires that errno is set
 }

Output:
 Hello World
