|

<p ><code>printf</code> statement rewritten (as <code>min_printf</code>) in C without using the <code>stdio.h</code> library Syntax of <code>min_printf</code> is same as <code>printf</code> Currently min_printf handles: Integers, Doubles, floats, characters and strings The format specifiers and escape sequence is the same as for <code>printf</code> User can also specify the width and precision if required, just like in the case of <code>printf</code> How to use it:</p><ul>
|
|
<li>First include <a class="el" href="../../d9/deb/min__printf_8h.html" title="Implementation of a function similar to printf">min_printf.h</a> in your code</li>
|

<li>Then type <code><a class="el" href="../../d9/deb/min__printf_8h.html#a33e08c05f8c656a0fee465c2e8d2ecf9" title="min_printf is the function same as printf">min_printf()</a></code>, and pass required parameters to it</li>
