Decode Status Register into Human-Readable Flags

Code

#include <stdio.h>
#include <stdint.h>
char arr[8][15] = {"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; status_reg; i++)
    {
        if(status_reg&1)
        {
            printf("%s\n", arr[i]);
        }
        status_reg >>=1;
    }
    return;
}

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