Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg) {
    // Your logic here
    uint8_t n=0;
    uint8_t temp=0;
    while (n<8){

        temp=(status_reg>>n )&1;
        
        if (temp&&(n==0)){
            printf("Power On\n");

        }
        else if  (temp&&(n==1)){
            printf("Error\n");

        }

        else if (temp&&(n==2)){
            printf("Tx Ready\n");

        }
        else if (temp&&(n==3)){
            printf("Rx Ready\n");

        }
        else if (temp&&(n==4)){
            printf("Overheat\n");

        }
        else if (temp&&(n==5)){
            printf("Undervoltage\n");

        }
        else if (temp&&(n==6)){
            printf("Timeout\n");

        }
        else if (temp&&(n==7)){

            printf("Reserved\n");

        }
        n++;
        
    } 
}

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