Boiling water has a temperature of 100 C and because all energy added to the water works to cause the change for liquid to a gas.
Boiling water will keep that temperature until it all evaporates.
But once it has changed to steam, the energy that was causing the phase change can make the steam increase in temperature.
Because of this the temperature of steam can often be many degrees above 100 C.

The first answer is right. Steam can be much hotter than boiling water. No matter how much heat you put into liquid water, the temperature of the liquid water will not be higher than the boiling point. If you put heat into water vapor, the temperature increases. This is because of the phase change from liquid to gas. If you put the steam under pressure, it can get very hot indeed.

because the steam means that the water was so hot that it turned into steam once water is boiling hot it will evapurate into steam!

Because it can be much hotter. It is called superheated steam.
