Decode Status Register into Human-Readable Flags

Code

#include <stdio.h>
#include <stdint.h>
void decode_status(uint8_t status_reg) {
    const char *flag_names[] = {
        "Power On",     
        "Error",        
        "Tx Ready",     
        "Rx Ready",     
        "Overheat",     
        "Undervoltage", 
        "Timeout",     
        "Reserved"      
    };
    for (int i = 0; i < 8; i++) {
        if ((status_reg >> i) & 1) {
            printf("%s\n", flag_names[i]); 
        }
    }
}
int main() {
    uint8_t reg;
    scanf("%hhu", &reg);
    decode_status(reg);
    return 0;
}
