What about<br />
<br />
int x1=0x01;<br />
<br />
printf(&quot;%2.2x&quot;, x1);<br />
<br />
?<br />

</div>


What about

int x1=0x01;

printf("%2.2x", x1);

?


<div>
you can use standard itoa() function:<br />
<br />
char hex[3];<br />
int x1 = 0x01; &nbsp;/* there is a missing = sign in your example */<br />
<br />
itoa (x1, hex, 16);<br />
<br />
/* now your digits are hex[0] and hex[1] */<br />
printf(&quot;%c %c&quot;, hex[0], hex[1]);<br />
<br />

</div>

<div>
<br />
void main()<br />
{<br />
int n=0xAB;<br />
char sol[2];<br />
sprintf(sol,&quot;%x&quot;,n);<br />
printf(&quot;%c and %c are the 2 digits&quot;,sol[0],sol[1]);<br />
}<br />
<br />
PS&gt; Hope this helps<br />

Hi i am trying to convert the two digit hex value of unprintable chars into two seperate chars, then i can print them as part of a normal C-String<br />
<br />
I Have tried<br />
<br />
char char1, char2;<br />
int x1 0x01;<br />
<br />
char1 = (x1/16)+'0';<br />
char2 = (x1%16)+'0';<br />
<br />

splitting digit hex codes into 2 chars

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.
