help in comparing

[Siva]

Hi,

I'm working a long code, part of which is as follows.

I get 2 numbers from 2 different field. Now I want to compare the 2
mumbers and see if atleast one of the digits are matching. for example:
A=123 and B=435. And I want to check if atleast one of the digit is
matching. In this case 3.

Can some one help me with this?

Thank You.

Siva.

Read in the two numbers in as strings. Scan through the strings and
build a list of the digits represented. If any digits appears twice in
the list, you have a match.

Myself, I'd probably convert them to strings then just do comparisons.

What exactly do you mean by "compare" and "match"?
In your example, you say that the digit '3' "matches"
between the strings "123" and "435". And yet, it doesn't
"match" in a place-value sense. Do you mean in a "set"
sense? That is, "is the intersection of the sets {1,2,3}
and {3,4,5} non-empty?"? If so, look-up information on
std::set. You could put all the digits of one number-string
in a std::set, then iterate through the digits of a second
number-string and ask, for each digit, if it matches any
element of the set.

But I'm just guessing at your intentions. If you clarified
what you mean by "compare" and "match", perhaps I could help
more.

Well, Robbie, what part of his example didn't you understand? But I'm just
guessing at your problem. Perhaps if you clarified where your problem
originates, I could help you more.

Convert both the numbers in to string using itoa() function and then
compare each character of first string with each character of second.

cheers,

Thank you guys. I wanted to compare the digits in 2 numbers in my
example 123 and 435, and to see if atleast one digit matches. I joined
the 2 numbers and looked for repetition.

Thank You again.

If "join" means concatenate, I don't like it. If you "join" 1223 and 579
you don't want a match.
