Decode Status Register into Human-Readable Flags

Code

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

void printPowerOn(){printf("Power On\n");}
void printError(){printf("Error\n");}
void printTxReady(){printf("Tx Ready\n");}
void printRxReady(){printf("Rx Ready\n");}
void printOverHeat(){printf("Overheat\n");}
void printUnderVoltage(){printf("Undervoltage\n");}
void printTimeout(){printf("Timeout\n");}
void printReserved(){printf("Reserved\n");}

typedef void (*PrintFn)();
PrintFn PrintFnArr[]={printPowerOn,printError,printTxReady,printRxReady,printOverHeat,printUnderVoltage,printTimeout,printReserved};
#define GET_BIT(reg,bit) (((reg) >> (bit)) & 1U)
void decode_status(uint8_t status_reg) {
    // Your logic here
    for(int i=0;i<8;i++)
    {
        if(GET_BIT(status_reg,i))
        {
           PrintFnArr[i](); 
        }
    }
}

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