Constexpr ADC Temperature Table

#include <iostream>
using namespace std;

// Create constexpr lookup table here:
constexpr int32_t TEMP_TABLE[6]={-40,-10,20,50,80,120};
int main() {
    int idx;
    cin >> idx;

    // Print the value from TEMP_TABLE based on idx
    printf("%d",TEMP_TABLE[idx]);
    return 0;
}
