Decode Status Register into Human-Readable Flags

Code

#include <stdio.h>
#include <stdint.h>
const char *status_Meaning[] = {
    "Power On",
    "Error",
    "Tx Ready",
    "Rx Ready",
    "Overheat",
    "Undervoltage",
    "Timeout",
    "Reserved"
};
void decode_status(uint8_t status_reg) {
    // Your logic here
    uint8_t bit = status_reg;
    for(int i =0; i <=7;i++){
        bit = status_reg % 2;
        if(bit == 1){
            printf("%s\n",status_Meaning[i]);
        }
        // printf("%d",status_reg);
        status_reg = status_reg/2;
    }
}

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