SensorBuffer Fixed Storage

#include <iostream>
using namespace std;

// Define SensorBuffer class here
// <write your code>
class SensorBuffer {
    private:
        int id;
        int data[5];
        int count;
    public:
        SensorBuffer(int i):id(i),count(0){}
        void addSample(int v){
            if (count == 5) return;
            data[count] = v;
            count++;
        }
        int size(){
            return count;
        }
        void print() const{
            if (count == 0) return;
            for(int i=0; i<count; ++i) cout<<data[i]<<" ";
        }
};

int main() {
    int id, n;
    cin >> id >> n;

    SensorBuffer buf(id);

    for (int i = 0; i < n; i++) {
        int x;
        cin >> x;
        buf.addSample(x);
    }

    buf.print();
    return 0;
}
