Re: String compare

int distance = 0;
int val = 0;
int x= 8;
int y=15;
val = x ^ y;

while(val!=0)
{
++distance;
val = val - 1;
}



but the distance that i get is 7, same as val... i was thinking of
converting 7 to binary and count the number of 1's (111) that way i
could get distance 3..

Hi !!
i want to compare two strings and return the difference

For example, i have two strings,
string str1="then";
string str2="than";

it compared the two strings and returns 1, as only one character is
different (a and e).
Is there a function in c# that can do this??

I don't think so.

This is quite easy, so I suspect it is homework.  You won't learn if
you get somebody else to write the code for you.  If you have written
some code and are having trouble, then post it with a description of
the problem and we can probably help.

If it is not homework, then what is the application?  (I can think of
a number of issues with the specification as it stands, and the
resolution will depend on the application.)
