Decode Status Register into Human-Readable Flags

Code

#include <stdio.h>
#include <stdint.h>
void print_status(uint8_t n){
    switch(n){
        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:
            return;
    }
    return;

}
void decode_status(uint8_t status_reg) {
    // Your logic here
    uint8_t i=0;
    while(i<8){
        if(status_reg&(1<<i))
            print_status(i);
        i++;
    }
}

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