Problems with ADXL345 Accelerometer outputs

hello friends

i beginner in arduino. bought arduino uno , adxl345 3-axis accelerometer. copied code, gives me outputs shown in attached picture. know problem is? it's because of code or installation? should give me acceleration data in x, y , z directions, gives me question mark. thanx

below code used:

#include <wire.h>

#define device (0x53)    // adxl345 device address when sdo pin (12) grounded

void setup()
{
  wire.begin();        // join i2c bus (address optional master)
  serial.begin(115200);  // start serial output
 
  // wake accelerometer
  wire.begintransmission(device); // start talking adxl345 accelerometer on sen-10183 board: http://www.sparkfun.com/products/10183
  wire.write(0x2d); // address on accel want set: power_ctl
  wire.write(; // value on address: measure(
  wire.endtransmission();
}

void loop()
{
  // ask accel send it's xyz values
  wire.begintransmission(device); // start talking adxl345 accelerometer on sen-10183 board: http://www.sparkfun.com/products/10183
  wire.write(0x32); // address on accel want read
  wire.endtransmission();
 
  // receive xyz values
  wire.requestfrom(device, 6);
  byte data[6];
  (int i=0;i<6 && wire.available();i++) {
    data = wire.read();
  }
  wire.endtransmission();

  // parse them
  int x = data[0] | (((int)data[1])<<;
  int y = data[2] | (((int)data[3])<<;
  int z = data[4] | (((int)data[5])<<;
  char buf[100];
  sprintf(buf, "x:%d, y:%d, z:%d\r\n", x,y,z);
  serial.print(buf);

  delay(200);
}

thank u in advance
