Decode Status Register into Human-Readable Flags

Code

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



void decode_status(uint8_t status_reg) {
    // Your logic here
    const char *meaning[8] = {"Power On", "Error", "Tx Ready", "Rx Ready", "Overheat", 
                        "Undervoltage", "Timeout", "Reserved"};
    if(status_reg == 0){
        return;
    }
    
    for(uint8_t i = 0; i < (sizeof(meaning) / sizeof(meaning[0])); i++){
        
        if(status_reg & (1 << i)){
            printf("%s\n", meaning[i]);
        }
    }

}

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