Can the (if statement) have A counter on it?

hi read this.

i know if (if statement) can have counter on it.  count ten , stop hole program. 

here little bit of code want run 10 times , go (state = 0) ,
turn off arduino or stop code going on.

code: [select]


if (counter > maxnum) {   
    // turn led on:   
     state = 1;
   }
  else {
    // turn led off:
     state = 0;
     delay(10);
  } 




all of program

code: [select]


const int ledpin =  9;
int inputpin = a5;

int sensorvalue;
int counter = 0;

int maxnum = 200;

byte state;

void setup() {
  pinmode(ledpin, output);
  serial.begin(9600);
}

void loop() {
 
//   serial.print("input on pin 5:  ");
   // serial.println(sensorvalue);
   
   serial.print("led state:  ");
   serial.println(state);
   
  //  serial.print("counter:  ");
   // serial.println(counter);
   
 
   
sensorvalue = analogread(inputpin);


  if (state == 0)
   {
     counter++;
   }

  if (sensorvalue > 0) {   
    // turn led on:   
    digitalwrite(ledpin, high);
    counter = 0;
   }
  else {
    // turn led off:
    digitalwrite(ledpin, low);
    delay(10);
   } 

if (counter > maxnum) {   
    // turn led on:   
     state = 1;
   }
  else {
    // turn led off:
     state = 0;
     delay(10);
  } 
}

sounds want loop, code doesn't seem match requirements:

code: [select]

 if (state == 0)
  {
    counter++;
  }

so every pass through loop, want counter increment (as long sensor reading zero)?  with delay, gives 2 seconds before maxnum hit.
