Well, THis was my approach to the code.

C++ Syntax (Toggle Plain Text) 
  1. for (int a=0; a<str1.size();a++)
  2. {
  3. size_t  val=str2.find(str1[a]);
  4.  if(val==string::npos)
  5.   return false;
  6.   else 
  7.    str2.erase(val,val);
  8. }
  9. return str2.empty();
THough i dint try it out, hope it works fine.

A Small change would be .....

C++ Syntax (Toggle Plain Text) 
  1.  
  2.    str2.erase(val,val);
to
C++ Syntax (Toggle Plain Text) 
  1.    str2.erase(val,1);

Thanks to tux4life.

And....Another approach (maybe not the most efficient one):
C++ Syntax (Toggle Plain Text) 
  1. bool isAnagram(string str1, string str2)
  2. {
  3.   sort(str1.begin(), str1.end());
  4.   sort(str2.begin(), str2.end());
  5.   if(str1 == str2) return true;
  6.  
  7.   return false;
  8. }
(You'll need to include the algorithm header file, you can do this by adding the following include directive to your program: #include <algorithm> )
