how to convert decimal number to binary

[Plater]

hehe actually if you look (and if I had added in a section for every bit) they would print out in the correct order.

And I never claimed to be good at c/c++, just saying it didn't look like anyone had given a solid answer to the post

bitset<length> myBinary ((long) <your number>) ;

cout<<myBinary;

[AdrianH]

bitset<length> myBinary ((long) <your number>) ;

cout<<myBinary;

Hey, didn't know that one. Learn something every day. ;)

I suppose that we exist to learn.

GREAT: Two questions.
code for binary/hexadecimal/decimal <-->binary/hexadecimal/decimal.

GREAT: Two questions.
First, the code for binary/hexadecimal/decimal <-->binary/hexadecimal/decimal.

Second, is there a reference text/site which has indexed code snippets for math/engineering C++.

TIA

The binary conversions should be above.
Hex is simple.
.ToString("X") on any integer will give you it's value as a hex string.
Int.Parse(strin g); is overloaded with a 2nd value stateing if it should accept a hex string or not.

Too bad this isn't C++.

Ooops, didn't notice what forum I was in. (got this outa control pannel)

I am "borrowing" this code from an embeded development helpfile and modifying it. My C is a little rusty
[code=c]
BYTE FromHexHelper(c har digit)
{
if(digit<='9')
return(digit-'0');
else
return((toupper (digit)-'A')+10);
}

BYTE FromHex(char[2] hexdigit)
{
int lo,hi;

hi = FromHexHelper(h exdigit[0]);
lo = FromHexHelper(h exdigit[1]);
if(lo==0xdd)
return(hi);
else
return( hi*16+lo );
}

//pass in a char[2] (or bigger) array to hexdigit
void ToHex(byte val, char *hexdigit)
{
byte hi=0x00;
byte lo=0x00;

hi=0xF0&val;
lo=0x0F&val;
//you could do a switch statement on hi and lo to determine 0-9A-F
//then populate hexdigit[0] and hexdigit[1]
}
[/code]

a program that takes a decimal number input from the user and displays its binary number equivalent in 12 bits on the screen.

For example:
Enter a decimal number: 32
Its Binary Equivalent is : 000000100000

hi,
i am new to the forum can you suggest me how to send my queries and how to view the replies to my queries?

You could repeatedly extract one nibble at a time from your value, using that nibble to index into an array of strings. The binary-string array contains 4-character strings such as "0000", "0001", etc. The hex-string array contains 1-character strings such as "0", "1", etc. Each such array has 16 entries.

How many nibbles are in the value? You either have to have secret knowledge of your compiler that you hard-code into your software or perhaps you could look at <limits.h> to see if your program can adapt itself to the compiler.

No one has mentioned an algorithm to solve this.

To check that a bit is set in a binary column, all you do is:

(32/32) = 1 and 1%2 is 1 the 32-bit is set
(32/16) = 2 and 2 % 2 is 0 the 16-bit is not set
etc...

If you're using STL bitsets you can do myBitset.test(p osition);
