Decode Status Register into Human-Readable Flags

Code

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

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

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