a < b ? b : a

[desktop]

I seem to have figured out that:

a < b ? b : a

returns a when a < b = false and b when a < b = true

but what is the statment:

Exp ? Exp : Exp

called? Could not find anything describing it in my book Accelerated C++

The official name of that _operator_ is "conditional". As in
"the conditional operator". It's the only *ternary* operator
in C++ (one that has three operands). It's not overloadable.

The operator is called the Conditional Operator and an expression
using it like your example is a Conditional Expression.

cond ? expr1 : expr2;
I think they are the same.

It's on page 45, where it's described as the "conditional operator"

Page 45, in turn, is mentioned in the index under the "?:" heading.

It's called the conditional operator, though it's also commonly known
as the ternary operator, since it's the only one in C++.
