i am a beginner .can you give me idea how we can manipulate "LARGE" integers (positive or negative) of arbitrary size. These integers could be greater than MAX_INT or smaller than MIN_INT.
using arrays or string?

Just use the BigInteger class.
kind regards,
Jos
i mean without using bigintegers and number can be greater than big integer also........... ....i.e 999999999999999 999999999999999 999999999

Do you mean you want to use big integers but you don't want to use the BigInteger
class? How strange ... can you explain why you want to restrict yourself?

i want to know how it works because i am making progamme in ocaml to calculate big integers without using any directories.... ....pls help .....give me idea....how i can add two big integer in two different list or array?????????? ??

A BigInteger doesn't use any directories; I don't know who told you that. The
following example calculates 1000! (factorial). See how simple it is: -
BigInteger fac= BigInteger.ONE;
-
for (int i= 2; i <= 1000; i++)
-
fac= fac.multiply(new BigInteger(""+i));
-
System.out.println("1000! = "+fac);
-
Read the API documentation for this class and see how one of its constructors
can create a BigInteger given some other representation of such a number.
kind regards,
Jos

I searched around on the net for a bit, couldn't find anything though.
I would like to find some code for a function where I input A Range Of
Integers
For example: Function( 1, 100 );
And the function will return me an array holding a random subset of integers
in that range of a size that I specify
So the Function would Probabaly look something like this:

Hi,
Im doing a multiplication of two large integers which are store in arrays(such as 2345 is in array as 2 in a, 3 in a and so on)like this im storing integers in two arrays.The logic i have used is explained with code below,
class large{
int no; //array is used to store the large number. Each digit of a the number is stored as an element..
// 123 is stored as no={1,2,3}
public:

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
