Sounds like homework. Why do you want it done that way?

yes it is a homework. Its program that accepts two numbers of 256 digits each and after accepting two numbers it adds those two. Is there another way of doing it?

Thanks

I can write simple program declaring two integer variable but my only problem is 256 digits limit.

Well, use a byte - not a char. A char in the .NET world is unicode and thus not 8 bits anyways, apart from not being a numeric type alltogether.

OK, basically don't think of it as character arrays.  Use two strings to read in the values.  Then you have to remember your old grade school addition:

345678
+24601
---------
370279

Just start from the end of each string and add the two numbers together (you can convert the characters to numbers in a number of ways, my favorite is (byte)NextCharacter - 48)  Don't forget to handle the case where you have to carry a one over to the next column.  Build your result string as you go.

Was that vague enough to pass EE guidelines yet specific enough to help?
