71. Decode ADC Result Using Union Bitfields

#include <stdio.h>
#include <stdint.h>

typedef union
 {
    struct
    {
        uint16_t adc_value : 12;
        uint16_t channel   : 4;
    };
    uint16_t adc_reg;
} ADC_Result;

int main() {
    ADC_Result d;
   
    uint16_t reg;
    scanf("%hx", &reg);
   d.adc_reg=reg;
    // Fill union and print channel and adc_value
      printf("Channel: %d\n",d.channel);
        printf("ADC Value: %d",d.adc_value);
        
    return 0;
