Any advice on how to repeat the song 6 times instead of infinitely?

Question

//Here is my code so far

int speakerPin = 9;
int length = 28;
char notes[] = "GGAGcB GGAGdc GGxecBA yyecdc";
int beats[] = { 2, 2, 8, 8, 8, 16, 1, 2, 2, 8, 8,8, 16, 1, 2,2,8,8,8,8,16, 1,2,2,8,8,8,16 };
int tempo = 150;
void playTone(int tone, int duration) {
for (long i = 0; i < duration * 1000L; i += tone * 2) {
digitalWrite(speakerPin, HIGH);
delayMicroseconds(tone);
digitalWrite(speakerPin, LOW);
delayMicroseconds(tone);
}
}
void playNote(char note, int duration) {
char names[] = {'C', 'D', 'E', 'F', 'G', 'A', 'B',
             'c', 'd', 'e', 'f', 'g', 'a', 'b',

             'x', 'y' };


int tones[] = { 1915, 1700, 1519, 1432, 1275, 1136, 1014,
             956,  834,  765,  593,  468,  346,  224,

             655 , 715 };


int SPEE = 5;
for (int i = 0; i < 17; i++) {
if (names[i] == note) {
    int newduration = duration/SPEE;
     playTone(tones[i], newduration);
}
}
}
void setup() {
pinMode(speakerPin, OUTPUT);
}
void loop() {
for (int i = 0; i < length; i++) {
if (notes[i] == ' ') {
 delay(beats[i] * tempo);


} else {
 playNote(notes[i], beats[i] * tempo);


}
delay(tempo);
}
}

Answer 1

Assuming, the program can stop after playing 6 times, put another for loop in the loop function:

void loop() 
{
   for (int nTimes = 0; nTimes < 6; nTimes++)
   {
      // Existing loop code
   }
while(true) {};
}

A less crude way is to create a global variable:

int _timesPlayed = 0;

And change the for loop:

void loop() 
{
   if (_timesPlayed < 6)
   {
      // Existing loop code
 _timesPlayed++;

}
}
