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++)
    {
        if(status_reg&(1<<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;}
            }
        }
    }
}

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