std::putchar(3) 	       C++ Standard Libary		 std::putchar(3)

NAME
     std::putchar - std::putchar

Synopsis
	Defined in header <cstdio>
	int putchar( int ch );

	Writes	a character ch to stdout. Internally, the character is converted
     to unsigned
	char just before being written.

	Equivalent to std::putc(ch, stdout).

Parameters
	ch - character to be written

Return value
	On success, returns the written character.

	On failure, returns EOF and sets the error indicator (see std::ferror())
     on stdout.

Example
     // Run this code

      #include <cstdio>

      int main()
      {
	  for (char c = 'a'; c != 'z'; ++c)
	      std::putchar(c);

	  // putchar return value is not equal to the argument
	  int r = 0x1024;
	  std::printf("\nr = 0x%x\n", r);
	  r = std::putchar(r);
	  std::printf("\nr = 0x%x\n", r);
      }

Possible output:
      abcdefghijklmnopqrstuvwxy
      r = 0x1024
      $
      r = 0x24
