Decode Status Register into Human-Readable Flags

Code

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

#define REGSIZE 8

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

void decode_status(uint8_t status_reg) {
    // Your logic here
    uint8_t pos = 0;
    while(pos < REGSIZE) {
        if ((status_reg >> pos) & 1) {
            printf("%s\n",convert[pos]);
        }
        pos++;
    }
}

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