将 Function C++ 转换为 Arduino [暂停]

Question

您要更改为 Arduino 的代码：

string encryptDecrypt(string toEncrypt) {
  char key[3] = {'K', 'C', 'Q'};
  string output = toEncrypt;
  for (int i = 0; i < toEncrypt.size(); i++) {
    output[i] = toEncrypt[i] ^ key[i % (sizeof(key) / sizeof(char))];
  }
  return output;
}

有什么想法吗？

谢谢

    please try it .......
