Decode Status Register into Human-Readable Flags

Code

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

#define check(num,pos) (num & (1<<pos))

void decode_status(uint8_t status_reg) {
    // Your logic here
    for(int i=0;i<8;i++){
        if(check(status_reg,i)){
            switch(i){
                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;
                default:
                printf("Unknown");
            }
        }
    }
}

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