void setup() {
Serial.begin(9600);
printArr([64,67]);
}
void loop() {}
void printArr(byte nilai[]) {
for (byte c = 0; c < length(nilai); c++) {
Serial.println(nilai[c]);
}
}
I expect the program print char of number 64 and 67 in ASCII since it was iterated in array, but instead the compiler give me error
C:\Users\User\Documents\Arduino\sketch_apr18a\sketch_apr18a.ino:10:24: note: suggested alternative: 'long'
for (byte c = 0; c < length(nilai); c++) {
^~~~~~
long
exit status 1
expected identifier before numeric constant
A solving can be:
void setup() {
Serial.begin(9600);
byte arr [] = {64,67};
printArr(arr, 2);
}
void loop() {}
void printArr(byte *nylai, unsigned d) {
for (byte c = 0; c < d; c++) {
Serial.println(*(nylai + c * sizeof(byte)));
}
}
