Arduino:
搜索和替换文本

String originalText = "I like apples.";
String searchText = "apples";
String replacementText = "oranges";
String replacedText;

void setup() {
  Serial.begin(9600);
  // 文本替换
  if (originalText.indexOf(searchText) != -1) {
    replacedText = originalText.substring(0, originalText.indexOf(searchText)) 
    + replacementText 
    + originalText.substring(originalText.indexOf(searchText) + searchText.length());
  } else {
    replacedText = originalText;
  }
  // 显示结果
  Serial.println(replacedText);
}

void loop() {
  // 程序未在loop()部分运行
}
