    Always. No excuses. Yes, I've heard them all before, and no, I'm not interested in hearing them again. Just use it.

    >int a = 12;
    You don't use this, and in the current code it's just filler anyway.

    >clrscr();
    This is a great way to ........ users off. I can guarantee that if I start a console program and it clears all of my previous output from other programs, I'll never use it again.

    >count++;
    You just invoked undefined behavior by accessing an indeterminate value from an uninitialized variable.

    >how can I re-write this as a while loop?
    If you don't mind the binary value in reverse, it's trivial:

    If you do mind, you need to cache the results and then print them properly. Using an array, for example.
    Well its just college C... I included the files I needed or duh it won't complile mr 9000 + posts!

    Plus the 12 is just as a refernece for ease-of-use to get the thing working...

    And yes your code works nicely! But I DO remind reverse... does anyone know how to make it print the right-way-round?

    Then put it in your posts. And don't make Prelude angry.

    Sorry about making whoever angry... I really didn't mean to, hes clearly pro tho and me mr noooob.


    But yeah which do I want? the right way round, with the while loop!
    His version prints it backwards, heh :S and no u can't just store it as a string then like swap it round ;(

    who can do it!

    A whole bunch of us can do it. Let's see your attempt. Lazy. You haven't done a damn thing here, other than cry because people are "clearly pro". You're not "mr noooob". You're "mr. too ........ing lazy to even make an attempt".

    Hope is the first step on the road to disappointment.

    Okay you can take whatever anger out on me its kewl!

    But anyways here's my attempt... :S

    Code:
    #include <stdio.h>
    #include <conio.h>
    
    void convert(int);
    
    main (){
    	int x;
    	//Sample X
    	x = 12;
    
    	clrscr();
    
    	convert(x);
      getche();
    }
    
    int convert(int x){
    
    	int z,i,ans, d = 0x00, count=1;
    
    	printf("X (%x) or D (%x) \n",x,d);
    
    	z = x & d;
    
    	for (i = 0; i <8; i++){
    
    		if (z>0){printf("1");}
    		if (z<0){printf("0");}
    
    		if (count >= 4){printf(" "); count = -1;}
    
    		z = z<<1;
    		count++;
    	}
    }

    Do you think your program prints some think. It dosn't. Well before that aren't u trying to print the binary values in the right form??

    Yeah, so
    Anyways, here's how the code should look:
    Code:
    #include <stdio.h>#include <conio.h>	//Eww. See below.
    void convert(int);
    int main (void){	
         int x;	//Sample X	
         x = 12;	
         //clrscr();	
         convert(x);  
         getche();	//Eww. View the FAQ.
    }
    int /*void*/ convert(int x)
    {	
         int z,i,ans, d = 0x00, count=1;	
         printf("X (%x) or D (%x) \n",x,d);	
         z = x & d;	
         for (i = 0; i <8; i++)
         {		
              if (z>0){printf("1");}		
              if (z<0){printf("0");}		
              if (count >= 4){printf(" "); 
              count = -1;
              }		
              z = z<<1;		
              count++;	
         }
    }
    That's the syntax stuff. The rest is for you to fix.

    What you didn't actually fix anything! Syntax-shmintax, it ran before, you're code didn't even run off the bat!

    still no dice on printing binary here, I think I'm about to cry! :'(
