length of an array arduino

This program prints out a text string one character at a time. Try changing the text phrase.

char myStr[] = "this is a test";

void setup() {
  Serial.begin(9600);
}

void loop() {
  for (byte i = 0; i < sizeof(myStr) - 1; i++) {
    Serial.print(i, DEC);
    Serial.print(" = ");
    Serial.write(myStr[i]);
    Serial.println();
  }
  delay(5000);  // slow down the program
}
