// They are equal so this line will print
Serial.println("Equal");
}
else {
Serial.println("Not equal");
}
}
void loop()
{
}String str1 = String("CCCP");
String str3 = String("CCCP");
// Tests to see if str1 is equal to str3
void setup() {
Serial.begin(9600);
if(str1.equals(str3) == true) {
// They are equal so this line will print
Serial.println("Equal");
}
else {
Serial.println("Not equal");
}
}
void loop() {
// Nothing for loop()
}
