Decode Status Register into Human-Readable Flags

Code

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

const char *flag_names[8]={
    "Power On",
    "Error",
    "Tx Ready",
    "Rx Ready",
    "Overheat",
    "Undervoltage",
    "Timeout",
    "Reserved"
};

void decode_status(uint8_t status_reg) {

    for (int i=0;status_reg>0;i++)
    {
        if (status_reg & 0x01)
        printf("%s\n",flag_names[i]);
        status_reg>>=1;

    }

  /*
    if(status_reg & (1<<0))
        printf("Power On\n");
    if(status_reg & (1<<1))
        printf("Error\n");
    if(status_reg & (1<<2))
        printf("Tx Ready\n");
    if(status_reg & (1<<3))
        printf("Rx Ready\n");
    if(status_reg & (1<<4))
        printf("Overheat\n");
    if(status_reg & (1<<5))
        printf("Undervoltage\n");
    if(status_reg & (1<<6))
        printf("Timeout\n");
    if(status_reg & (1<<7))
        printf("Reserved");
    // Your logic here
    */

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