Having trouble controlling 3 Row Seven Segment with 4 shift register 74hc595

Using Arduino LEDs and Multiplexing
17

this my result and the unfinished codes

int latchPin = 10;
int clockPin = 9;
int dataPin = 8;

// digits from the right
const byte digit[10] =      //seven segment digits in bits
{
  B10000001,  // 0
  B11110011,  // 1
  B01001001,  // 2
  B01100001,  // 3
  B00110011,  // 4
  B00100101,  // 5
  B00000101,  // 6
  B11110001,  // 7
  B00000001,  // 8  fix
  B00100001,  // 9
};


void setup()
{
  Serial.begin(9600);
  pinMode(latchPin, OUTPUT);
  pinMode(dataPin, OUTPUT);
  pinMode(clockPin, OUTPUT);
}

void loop()
{
  // step through each digit then increment
  // the counter by one, until nine
  for (int j = 0; j < 10; j++) {
    Serial.println(j);
    updateShiftRegister(0, j);
    delay(1000);
  }
}

void updateShiftRegister(int col, int num)
{
  digitalWrite(latchPin, LOW);
  shiftOut(dataPin, clockPin, MSBFIRST, B00000101);
  shiftOut(dataPin, clockPin, MSBFIRST, digit[num]);
  digitalWrite(latchPin, HIGH);
}
