Decode Status Register into Human-Readable Flags

Code

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


void aff0(){printf("Power On\n");}
void aff1(){printf("Error\n");}
void aff2(){printf("Tx Ready\n");}
void aff3(){printf("Rx Ready\n");}
void aff4(){printf("Overheat\n");}
void aff5(){printf("Undervoltage\n");}
void aff6(){printf("Timeout\n");}
void aff7(){printf("Reserved\n");}





void decode_status(uint8_t status_reg) {
    // Your logic here
    void (* aff[8]) (){
        &aff0, &aff1, &aff2, &aff3, &aff4, &aff5, &aff6, &aff7
    };
    for(int i = 0; i < 8; i++){
        if(((1 << i) & status_reg) > 0 ){
            aff[i]();
        }
        
    }
}

int main() {
    uint8_t reg;
    scanf("%hhu", &reg);
    decode_status(reg);
    return 0;
}
