Decode Status Register into Human-Readable Flags

Code

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

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

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