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