Decode Status Register into Human-Readable Flags

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

int decode_status(uint8_t reg) {
    // Your logic here
    int i=0;
    if (reg == 0)
    {
        printf("No flags are enabled");
        return 0;
    }
    while(i<=7)
    {
        uint8_t result = 1<<i;
        //if(((reg>>i)&0x01)==1)
        if(reg & (1<<i))
        {
            if(i==0)
                printf("Power On\n");
            else if(i==1) 
                printf("Error\n");
            else if(i==2)
                printf("Tx Ready\n");
            else if(i==3) 
                printf("Rx Ready\n");
            else if(i==4) 
                printf("Overheat\n");
            else if(i==5) 
                printf("Undervoltage\n");
            else if(i==6) 
                printf("Timeout\n");
            else if(i==7)

}

int main() {
