stay in the same value of analog input give output one time

If you have multiple input then yes, you need to distiguish them.

const int sensor[0] = A0;
const int sensor[1] = A1; 
const int sensor[2] = A2; // analog input use variable resistance
int flagged1, flagged2, flagged3 = 0;  
void check(int Num);

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

void loop ()
{
  for(Num = 0; Num<3; Num++)
    {
      check(Num);
    }
}

void check(int Num)
{
  if(analogRead(sensor[Num])==1023)//when variable resistance give value =1023 print 'x' 
  { 
   if(!flagged1 && Num == 0) 
    {
          Serial.print("x");
          Serial.println();
          flagged1 = 1;
     }
  else flagged1 = 0;

  if(!flagged2 &&  Num == 1) 
    {
          Serial.print("y");
          Serial.println();
          flagged2 = 1;
    }
  else flagged2 = 0;

  if(!flagged3 &&  Num == 2 ) 
    {
          Serial.print("z");
          Serial.println();
          flagged3 = 1;   
    }
  else flagged3 = 0;
 
   delay (100);
  }
return;
}

Let me check if this works or not.
Something like this, but maybe not as hectic.
