Decode Status Register into Human-Readable Flags

Code

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

void decode_status(uint8_t status_reg) {
    // Your logic here
    if (status_reg & 0x01)  printf("Power On\n");
    if (status_reg & 0x02)  printf("Error\n");
    if (status_reg & 0x04 )  printf("Tx Ready\n");
    if (status_reg & 0x08)  printf("Rx Ready\n");
    if (status_reg & 0x10)  printf("Overheat\n");
    if (status_reg & 0x20)  printf("Undervoltage\n");
    if (status_reg & 0x40)  printf("Timeout\n");
    if (status_reg & 0x80)  printf("Reserved\n");
}

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

Solving Approach

bitwise AND with proper bits
