Is it possible to make a variable that is greater than something and less than?

Using Arduino Project Guidance

Hello, is it possible to make a variable greater than something and less than something else?
I have tried to make it but to no avail.

case '2':
       {sensorValue= analogRead(LOL);  // take out the int as not to re-define the Local variables
       int dist=map(sensorValue, 105.5, 606.52, 46.1, 0);
       Serial.print("Analog Reading: ");
       Serial.print(sensorValue);
       Serial.print(" Centemeters: ");
       Serial.print(dist);
       Serial.println("cm");
       delay(10);
       myservo.write(0);
        }
       while(150<sensorValue<600);
       break;
#2

150<sensorValue && sensorValue <600

#3

I tried it but it didnt work at all. Whenever I press the button the motor does nothing.

case '2':
      if(100<sensorValue && sensorValue<155)
       {sensorValue= analogRead(LOL); 
       int dist=map(sensorValue, 105.5, 606.52, 46.1, 0);
       Serial.print("Analog Reading: ");
       Serial.print(sensorValue);
       Serial.print(" Centemeters: ");
       Serial.print(dist);
       Serial.println("cm");
       delay(10);
       myservo.write(180);
        }
      else
      {sensorValue= analogRead(LOL); 
       int dist=map(sensorValue, 105.5, 606.52, 46.1, 0);
       Serial.print("Analog Reading: ");
       Serial.print(sensorValue);
       Serial.print(" Centemeters: ");
       Serial.print(dist);
       Serial.println("cm");
       delay(10);
       myservo.write(0);
      }

A quick search on the Programming Forum found an apparent solution, which makes sense:

Surely it also depends on what sensorvalue = in your test? if it is a value greater than 155 or less than 100 the argument will = False.

Edit to add:
In one of your other posts you mention an issue with it not stopping at 600? if you are testing if(100<sensorValue && sensorValue<600) and the value for the floor is 600 then the expression will always return false, 600 is not less than 600, the right test would need to be <= 600.
