Decode Status Register into Human-Readable Flags

Code

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

const char *Bit_Flag[]= {"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, p = 0x01; i < 8; i++, p <<= 1) {
        if (status_reg & p) {
            printf("%s\n", Bit_Flag[i]);
        }
    }

}

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