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 pos = 0;
    while(pos <= 7)
    {
        if(status_reg & (1 << pos))
        {
            if(pos == 0)
            {
                printf("Power On\n");
            }
            if(pos == 1)
            {
                printf("Error\n");
            }
            if(pos == 2)
            {
                printf("Tx Ready\n");
            }
            if(pos == 3)
            {
                printf("Rx Ready\n");
            }
            if(pos == 4)
            {
                printf("Overheat\n");
            }
            if(pos == 5)
            {
                printf("Undervoltage\n");
            }
            if(pos == 6)
            {
                printf("Timeout\n");
            }
            if(pos == 7)
            {
                printf("Reserved\n");
            }
        }
        pos++;
    }
}

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