expected initializer before void arduino

When I try to compile the following code in Arduino ,I get the error "expected initializer before 'void'".How can I get the code to work?

void setup() {  
  Serial.begin(9600);
}

float area = 0.0f,pre_area = 0.0f,tarea = 0.0f,rarea = 0.0f;
int x = 0,pre_x = 0,t = 0,pre_t = 0;


long unsigned int t


void loop()
{
  x = analogRead(A0);
  t = millis();
  float diff_t = (float)(t - pre_t)/1000.0f;
  area = (0.5 * (pre_x + x) * diff_t) + pre_area;

  Serial.print(area);
  analogWrite(DAC0, area);
  pre_x = x;
  pre_area = area;
  pre_time = t;
}

What's wrong with this?

long unsigned int t

The message you incorrectly paraphrased is NOT the message that you actually got. From that and the fact that you didn't post your code correctly, it is obvious that you didn't read the stickies at the top of the forum. If you can't be bothered to read a couple of short posts first, why should we be bothered to read yours?

@PPLJ - Wrong answer - try again.

Declarations end with a semicolon.
