Decode Status Register into Human-Readable Flags

Code

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

char STATUS_MEANING[8][15] = {"Power On\n", "Error\n", "Tx Ready\n", "Rx Ready\n", "Overheat\n", "Undervoltage\n", "Timeout\n", "Reserved\n"};

void decode_status(uint8_t status_reg) {
    // Your logic here
    for (int i = 0; i < 8; ++i) {
        if (status_reg & ( 1 << i)) {printf(STATUS_MEANING[i]);}
    }
}

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