Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg) {
    // Your logic here
    int i;
    for(i=0; i<(8*sizeof(uint8_t)); i++){
        if((status_reg>>i) & 1){
            switch(i){
            case 0: printf("Power On");
            break;
            case 1: printf("Error");
            break;
            case 2: printf("Tx Ready");
            break;
            case 3: printf("Rx Ready");
            break;
            case 4: printf("Overheat");
            break;
            case 5: printf("Undervoltage");
            break;
            case 6: printf("Timeout");
            break;
            case 7: printf("Reserved");
            break;
        }
        printf("\n");
        }
    }
}

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