Decode Status Register into Human-Readable Flags

Code

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

#define IS_BIT_SET(n, pos) (n & (1<<pos))

void decode_status(uint8_t status_reg) {
    // Your logic here
    char* arr[8] = {"Power On", "Error", "Tx Ready", "Rx Ready", "Overheat", "Undervoltage", "Timeout", "Reserved"};
    for(int i=0; i<8; i++){
        if(IS_BIT_SET(status_reg, i))
            printf("%s\n",arr[i]);
    }
}

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