Just parse the string however you see fit.
eg.
string = @"x * y";
char1 = [string characterAtIndex:0];
if (char1 == 'x')
return x * y;
You maybe be best looking at using an NSScanner instead, just read the
class description and see if it is for you.

Hi,
I read a string from a file.
This string contains:
@"x * y"
I already have two global int variables called "x" and "y".
Now I would like to get the product of x and y.
How should I do?
Best Regards
