Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg) {
    // Your logic here
    uint8_t flag = 0;
    while (status_reg){
        if (status_reg & 1){
            switch (flag){
                case 0:
                    printf("Power On\n");
                    break;
                case 1:
                    printf("Error\n");
                    break;
                case 2:
                    printf("Tx Ready\n");
                    break;
                case 3:
                    printf("Rx Ready\n");
                    break;
                case 4:
                    printf("Overheat\n");
                    break;
                case 5:
                    printf("Undervoltage\n");
                    break;
                case 6:
                    printf("Timeout\n");
                    break;
                case 7:
                    printf("Reserved\n");
                    break;
            }
        }
        status_reg >>= 1;
        flag += 1;
    }
    
}

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