Clouds are mists of water droplets that have condensed out of water vapour at "dewpoint", which is dependent on temperature, pressure, and humidity.
There is no intelligence or knowing involved.
Clouds don't fly, they are blown by the wind.

clouds form when the water vapor in the air condenses. The measure of water vapor in the air is the dewpoint.. thus, clouds form when the temperature of the air is at or below the dewpoint.
if it's 21C degrees at the ground, and the dewpoint is 10C, clouds will form at or below 10C.. that will be several thousand feet up typically. of course there can be temperature inversions, or other layering of the atmosphere that could change that
if you ever are flying, you will notice that clouds layer quite nicely, (all the bottoms are at the same altitude) because that is the altitude the temp/dewpoint meet.

Clouds start to form at the dew point especially the cumulus nature. Also where there is more moisture in the air more clouds you will see. Cirrus clouds are high because they are usually at the start of the front which is quite high as the front comes in then the clouds get lower as the front descends on you esp a warm front until you get stratus clouds which usually lie at the dew point and rain on you.

They are programmed to fly in different heights

It all depends on how much water vapor is in the clouds. The more water, the heavier it is. The heavier it is, the lower it will be.

Clouds don't have a mind of their own sweet heart.

they don't know anything it was kind of like jdimmit said it is only based on the density of watervapor in that particular cloud.

they form at condensation level ie where the air becomes so cold that it can no longer hold the water vapour. they will only form if tiny particles called condensation nucei are present.

Clouds don't KNOW anything. They have no brains or minds.
