Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg) {
    // Your logic here
    char status[8][20] = {"Power On", "Error", "Tx Ready", "Rx Ready", "Overheat", "Undervoltage", "Timeout","Reserved"};
    for(int i = 0; i<8; i++){
        if((status_reg >> i) & 1){
            printf("%s\n",status[i]);
        }
    }
}

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

Solving Approach

To check each bit, use shifting and masking with 1.
