I have searched left and right and I have to do an assignment on critiquing this (title)! Does anyone have links to a poorly documented code? If you can provide me with such a link I'd be soo grateful to you!

Hello there ^.^

I have recently installed DevC++ 5.11 version on my Windows machine. Everytime I run my program I get an error saying, "redefinition of main" and opens a header file "conio.h" simultaneously. I have tried uninstalling and reinstalling the DevC++ several times. And everytime I reinstall, the DevC++ only works first few times before it starts giving me that error D:

I will be really thankful if anyone can point towards what is happening. Any help is greatly appreciated.

@Norm The following is the code and I understand the question I asked now :P
The square brackets, meant array and hence the line hex[15] + hex[1] was referring to array index, hex[15] and hex[1] and the results were being added.
Thanks for looking into my problem \(^.^)/ Much Appreciated!

Gotchya! Thanks for clarifying that When I apply the edits,I think it goes into an infinite loop...since its not producing any output...unless I am doing something wrong :\

Hi Norm,

public class HexByte {

public static void main(String[] args) {

char hex [] = {'0','1','2','3','4','5','6','7','8','9',
'a','b','c','d','e','f' };
byte b = (byte) 0xf1;

System.out.println("b = 0x" + hex[(b>>4) & 0x0f] + hex[b & 0x0f] );



I have worked out hex[(b>>4) & 0x0f] + hex[b & 0x0f] to be hex[15] + hex[1] but I have no idea how will hex[15] + hex[1] works out D:

So I am currently trying to solve

hex[(b>>4) & 0x0f] + hex[b & 0x0f]

and I have worked it out until hex[15] + hex [1], But I dont know how to proceed from there...because, say the "hex" part wasnt there in the expression, wouldnt 15+1, considering they were decimals and we did not have to convert, be 16, which would be 0x10? D:

Then why does the console window give me an output of 0xf1..unless I am making a mistake in working it out...

Any help or contribution will be greatly appreciated. Thanks.
