Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg)
{
    char *statusflags[]={"Power On","Error","Tx Ready","Rx Ready","Overheat","Undervoltage","Timeout","Reserved"};
    uint8_t t =1;
    for(int i=0;i<8;i++)
    {
        if((status_reg & t)!=0)
        {
            printf("%s\n",statusflags[i]);
        }
        t <<=1;
    }
}

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