Read serial data into array for smoothing filter

i'm newbie , trying smoothing data...
the data in 14byte cr n nl....
pls me
for exm= 0000.1000010

0000.2000010
0001.1000010
0000.1000010
0000.1000010
0000.1000010
0000.1000010
0000.1000010


i'm refer code
/*

  smoothing

  reads repeatedly analog input, calculating running average
  , printing computer.  keeps ten readings in array and
  continually averages them.

  circuit:
    * analog sensor (potentiometer do) attached analog input 0

// define number of samples keep track of.  higher number,
// more readings smoothed, slower output will
// respond input.  using constant rather normal variable lets
// use value determine size of readings array.
const int numreadings = 10;

int readings[numreadings];      // readings analog input
char readindex = 0;              // index of current reading
int total = 0;                  // running total
int average = 0;                // average

int inputpin = a0;

void setup() {
  // initialize serial communication computer:
  serial.begin(9600);
  // initialize readings 0:
  (int thisreading = 0; thisreading < numreadings; thisreading++) {
    readings[thisreading] = 0;
  }
}

void loop() {
  // subtract last reading:
  total = total - readings[readindex];
  // read sensor:
  readings[readindex] = analogread(inputpin);
  // add reading total:
  total = total + readings[readindex];
  // advance next position in array:
  readindex = readindex + 1;

  // if we're @ end of array...
  if (readindex >= numreadings) {
    // ...wrap around beginning:
    readindex = 0;
  }

  // calculate average:
  average = total / numreadings;
  // send computer ascii digits
  serial.println(average);
  delay(500);        // delay in between reads stability
}

ok, new. want smooth data. have sample that. understand. haven't stated need on.

what part of sketch not understand? need help?
