Decode Status Register into Human-Readable Flags

Code

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

const char* flags[]=
{
   "Power On",
   "Error",
   "Tx Ready",
   "Rx Ready",
   "Overheat",
   "Undervoltage",
   "Timeout",
   "Reserved" 
};

void decode_status(uint8_t status_reg) {
    // Your logic here
    for(int i=0; i<8; i++)
    {
        if(status_reg & (1U << i))
            printf("%s\n", flags[i]);
    }
}

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