Decode Status Register into Human-Readable Flags

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

#define check(D,n) ((D) &(1<<(n)))

void decode_status(uint8_t status_reg) {
    // Your logic here
    for(unsigned int i=0;i<8;i++){
        if (check(status_reg,i)){
            if (i==0)
                printf("Power On\n");
            else if(i==1)
                printf("Error\n");
            else if(i==2)
                printf("Tx Ready\n");
            else if(i==3)
                printf("Rx Ready\n");
            else if(i==4)
                printf("Overheat\n");
            else if(i==5)
                printf("Undervoltage\n");
            else if(i==6)
                printf("Timeout\n");
            else
                printf("Reserved");
        }     
    }   
}

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