C++ STL: Trouble with iterators
- by Rosarch
I'm having a beginner problem:
bool _isPalindrome(const string& str)
{
return _isPalindrome(str.begin(), str.end()); // won't compile
}
bool _isPalindrome(string::iterator begin, string::iterator end)
{
return begin == end || *begin == *end && _isPalindrome(++begin, --end);
}
What am I doing wrong here? Why doesn't str.begin() get type checked to be a string::iterator?
