Sort the strings and check if they are equal.

I suggest you use hashing. A good hashing function in this case is adding the characters, since anagrams will result in the same sum!

int hash(string s) {
  int sum = 0;
  for (auto c : s) sum += c;
  return sum;
}

bool anagram(string s, string t) {
  return hash(s) == hash(t);
}

No way this goes wrong!

I think this code helps with your problem, although it's a bit long, it is easily understandable and a brute-force solution.

Hope you find it easy...
