Decode Status Register into Human-Readable Flags

Code

#include <stdio.h>
#include <stdint.h>
const char *flagNames[] = {
    "Power On", 
    "Error", 
    "Tx Ready", 
    "Rx Ready", 
    "Overheat", 
    "Undervoltage",
     "Timeout", 
     "Reserved"
};
void decode_status(uint8_t status_reg) {
    // Your logic here
    int count = 0;
    for (int i = 0 ; i <= 7; i++){
        if(status_reg>>i & 1)
            printf("%s\n", flagNames[i]);
    }
  
}

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