hello guys, salam arduino
how to read many array using variable int..

2

Please give an example of what you want to do

Are there many arrays or a single array with many entries ?

3

I wanna count my array this is my program example thankyou

int house[] = {1,13,15,16,17,3,19,20};
int countarrayhouse;
void setup(){
Serial.begin(9600);

Serial.println (countarrayhouse)
}
void loop(){}
4

which is actually my array very much number

Do you just want to count how many entries there are in the array or perhaps total the values in the array ?

The classical way would be:

int house[] = {1, 13, 15, 16, 17, 3, 19, 20};
int countarrayhouse = sizeof(house) / sizeof(house[0]);

[edit]

Or my personal favorite:

template <class T, size_t n> size_t arraySize(T const (&)[n]) { return n; }

int house[] = {1, 13, 15, 16, 17, 3, 19, 20};
int countarrayhouse = arraySize(house);

just how many entries my array

But you must already know how many entries there are in the array in order to declare it

What are you really trying to do ?
