Be careful of difference between  c  and  c    c  is a char suitable for formatting with  c   c  is a char  pointing to a memory block with a length of 2  with the null terminator

As mentioned in one of the other answers  you can use putc int c  FILE  stream   putchar int c  or fputc int c  FILE  stream  for this purpose   What s important to note is that using any of the above functions is from some to signicantly faster than using any of the format-parsing functions like printf   Using printf is like using a machine gun to fire one bullet

The easiest way to output a single character is to simply use the putchar function  After all  that s it s sole purpose and it cannot do anything else  It cannot be simpler than that

yes   c will print a single char   printf   c    h      also  putchar putc will work too  From  man putchar     include  lt stdio h gt   int fputc int c  FILE  stream   int putc int c  FILE  stream   int putchar int c      fputc   writes the character c  cast to an unsigned char  to stream    putc   is equivalent to fputc   except that it may be implemented as a macro which evaluates stream more than once    putchar c   is equivalent to putc c stdout     EDIT   Also note  that if you have a string  to output a single char  you need get the character in the string that you want to output  For example   const char  h    hello world   printf   c n   h 4       outputs an  o  character
