To quote the standard (6.5.4.1/2):
"The expression ++E is equivalent to (E+=1). See the discussions of additive
operators and compound assignment for information on constraints, types,
side effects, and CONVERSIONS and the effects of operations on pointers"
emphasise mine, 6.5.6/4 then of course says
"If both operands have arithmetic type, the usual arithmetic conversions are
performed on them."
