Performs a very weak form of "encryption" by adding 13 to each character of the string. 

  
  string encrypt(const char* input)
  {
    char* encrypted = new char[strlen(input) + 1];
  
    for (unsigned int i = 0; i < strlen(input); i++) {
      encrypted[i] = input[i] + 13;
    }
    encrypted[strlen(input)] = '\0';
  
    string result(encrypted);
  
    delete[] encrypted;
  
    return result;
  }
