Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg) {
    // Your logic here
    const char *arr[8] = {
    "Power On",
    "Error",
    "Tx Ready",
    "Rx Ready",
    "Overheat",
    "Undervoltage",
    "Timeout",
    "Reserved"
};

    for(int8_t i=0; i<8; i++)
    {
        if((1U << i) & (status_reg))
        {
            printf("%s\n",arr[i]);
        }
        
    }
}

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