Yes:

int a = 0xA;
int b = 0xB;

printf ( "%x\n", a + b );

yeah, thats fine. but i want to do it in graphics and so for the alignment purpose i can't do it with a printf statement!
sorry, for posting an incomplete question.

Yea, that tells me absolutely nothing about your needs. Be more specific, please.

Assuming you're writing this to a label or text box (or pretty much any drawing mechanism), you would use sprintf to format the string first. I don't understand what you mean by "the alignment purpose", as the printf family is fully featured when it comes to alignment formatting.

printf, as narue said, is able to format quite well.

sumValue = firstValue + secondValue;
printf("   0x%04X\n", firstValue);
printf("+  0x%04X\n", secondValue);
printf("  --------\n");
printf("   0x%04X\n", sumValue);

i think we can just this one away for free.
