Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg) {
    // Your logic here
    for(int i =0;i< 8;i++){
        if(status_reg&1){
            if(i==0){ printf("Power On\n");}
            if(i==1){ printf("Error\n");}
            if(i==2){ printf("Tx Ready\n");}
            if(i==3){printf("Rx Ready\n");}
            if(i==4){printf("Overheat\n");}
            if(i==5){printf("Undervoltage\n");}
            if(i==6){printf("Timeout\n");}
            if(i==7){printf("Reserved");}
            
        }
        status_reg>>=1;
    }
}

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