Please format your code properly, remove the duplicate, and explain exactly where the error occurs.

I'm puzzled why you keep using 'new' instead of creating vectors of std::string.

There are other issues:

    
    while(std::getline(file, line))
    {
        words[i] = new char[line.length()];
        for(int j = 0; j < line.length(); ++j)
        {
            words[i][j] = line[j];
        }
        words[i][line.length()] = '\0';
        ++i;
    }

You are allocating line.length() and then assigning a terminating zero past the end of the allocation.

bool compairing_words(char * guess, word )
{
   for(int i=0; i < word->length(); i++ )
   {
      if(word[i]==guess)
      {
         return true;
      }
      return false;
   }
}


You return false after first check.

One problem appears to be the guess function. It should return a character, not accept one as an argument. It should look something like this :
C++
char guess_it( void )
{
    char guess;
    std::cout << " Guess a letter \n";
    std::cin >> guess;
    return guess;
}
