here is my code :

in my main() :

string TypeWord ;
 int plen ;
 cin >> TypeWord;
 plen = TypeWord.length();
 cout << plen;

if (VerifyWord(TypeWord,plen)) // here is my mistake
cout << TypeWord << " is in tree ";
else {
cout << TypeWord << "is not in tree." ;
here is my function VerifyWord :

bool VerifyWord(const char * word, int len)
  int plen;
  Dictio * n = root -> follow(word,len,plen);
  return (plen == len && n -> IsFullWord());
here is my error :
'VerifyWord' : cannot convert parameter 1 from 'class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >' to 'const char *'

Either change VerifyWord to look like:
bool VerifyWord(const std::string &word, int len)

or change the call to
if(VerifyWord(TypeWord.c_str(), plen))// c_str is the const char * conversion function
