Decode Status Register into Human-Readable Flags

Code

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

bool checkbit (uint8_t status_reg,int bit) 
{
    if (status_reg &= 1<<bit)
    {
        return true;
    }
    else
    {
        return false;
    }
}
void decode_status(uint8_t status_reg) {
    // Your logic here
    if(checkbit(status_reg,0))
    {
        printf("Power On\n");
    }
    
    if(checkbit(status_reg,1))
    {
        printf("Error\n");
    }
    
    if(checkbit(status_reg,2))
    {
        printf("Tx Ready\n");
    }
    
    if(checkbit(status_reg,3))
    {
        printf("Rx Ready\n");
    }
    
    if(checkbit(status_reg,4))
    {
        printf("Overheat\n");
    }
    
    if(checkbit(status_reg,5))
    {
        printf("Undervoltage\n");
    }
    
    if(checkbit(status_reg,6))
    {
        printf("Timeout\n");
    }
    
    if(checkbit(status_reg,7))
    {
        printf("Reserved\n");
    }
}

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