Description

Combine, ou "concatène" deux objets String en un seul nouvel objet String. La deuxième chaîne de caractère est accolée à la première, et le résultat est placé dans un nouvel objet String.

Syntaxe

string.concat(string2)

Paramètres

  • string et string2: deux variables de type String()

Valeurs Renvoyées

  • Un nouveau String qui est la combinaison des deux Strings de départs.

Exemple

void setup() { Serial.begin(9600); String myString = "Arduino"; Serial.println(myString); // string before myString.concat("GetStarted.com"); Serial.println(myString); // string after } void loop() { }

※ Remarque:

If the string is modified, it is highly recommended using String.reserve() to prevent the memory fragmentation issue
