Here is a table summarizing what all the different conversions do:
<dl>
<dt>‘<samp><span class="samp">%d</span></samp>’, ‘<samp><span class="samp">%i</span></samp>’<dd>Print an integer as a signed decimal number. See <a href="Integer-Conversions.html#Integer-Conversions">Integer Conversions</a>, for details. ‘<samp><span class="samp">%d</span></samp>’ and ‘<samp><span class="samp">%i</span></samp>’ are synonymous for
output, but are different when used with <code>scanf</code> for input
(see <a href="Table-of-Input-Conversions.html#Table-of-Input-Conversions">Table of Input Conversions</a>).
<br><dt>‘<samp><span class="samp">%o</span></samp>’<dd>Print an integer as an unsigned octal number. See <a href="Integer-Conversions.html#Integer-Conversions">Integer Conversions</a>, for details.
<br><dt>‘<samp><span class="samp">%u</span></samp>’<dd>Print an integer as an unsigned decimal number. See <a href="Integer-Conversions.html#Integer-Conversions">Integer Conversions</a>, for details.
<br><dt>‘<samp><span class="samp">%x</span></samp>’, ‘<samp><span class="samp">%X</span></samp>’<dd>Print an integer as an unsigned hexadecimal number. ‘<samp><span class="samp">%x</span></samp>’ uses
lower-case letters and ‘<samp><span class="samp">%X</span></samp>’ uses upper-case. See <a href="Integer-Conversions.html#Integer-Conversions">Integer Conversions</a>, for details.
<br><dt>‘<samp><span class="samp">%f</span></samp>’<dd>Print a floating-point number in normal (fixed-point) notation.
See <a href="Floating_002dPoint-Conversions.html#Floating_002dPoint-Conversions">Floating-Point Conversions</a>, for details.
<br><dt>‘<samp><span class="samp">%e</span></samp>’, ‘<samp><span class="samp">%E</span></samp>’<dd>Print a floating-point number in exponential notation. ‘<samp><span class="samp">%e</span></samp>’ uses
lower-case letters and ‘<samp><span class="samp">%E</span></samp>’ uses upper-case. See <a href="Floating_002dPoint-Conversions.html#Floating_002dPoint-Conversions">Floating-Point Conversions</a>, for details.
<br><dt>‘<samp><span class="samp">%g</span></samp>’, ‘<samp><span class="samp">%G</span></samp>’<dd>Print a floating-point number in either normal (fixed-point) or
exponential notation, whichever is more appropriate for its magnitude.
‘<samp><span class="samp">%g</span></samp>’ uses lower-case letters and ‘<samp><span class="samp">%G</span></samp>’ uses upper-case.
See <a href="Floating_002dPoint-Conversions.html#Floating_002dPoint-Conversions">Floating-Point Conversions</a>, for details.
<br><dt>‘<samp><span class="samp">%c</span></samp>’<dd>Print a single character. See <a href="Other-Output-Conversions.html#Other-Output-Conversions">Other Output Conversions</a>.
<br><dt>‘<samp><span class="samp">%s</span></samp>’<dd>Print a string. See <a href="Other-Output-Conversions.html#Other-Output-Conversions">Other Output Conversions</a>.
<br><dt>‘<samp><span class="samp">%%</span></samp>’<dd>Print a literal ‘<samp><span class="samp">%</span></samp>’ character. See <a href="Other-Output-Conversions.html#Other-Output-Conversions">Other Output Conversions</a>.
</dl>
<p>If the syntax of a conversion specification is invalid, unpredictable
things will happen, so don't do this. If there aren't enough function
arguments provided to supply values for all the conversion
specifications in the template string, or if the arguments are not of
the correct types, the results are unpredictable. If you supply more
arguments than conversion specifications, the extra argument values are
simply ignored; this is sometimes useful.
