No construction is truly intuitive and immediately understandable to everyone, 
but there are constructions that are less easy to understand than others. a==1 
and a+=1 both have few "moving parts" that you have to learn, and they combine 
with other constructions fairly straightforwardly. *ptr++=value has several 
moving parts, each of which are understandable separately, but understanding 
their separate functions does not give immediate understanding of their combined 
meaning. You not only have to learn the meaning of each component, you have to 
separately learn how they combine.
