One additional note regarding the differences between ?: and if(), as I mentioned in that thread, is that other control statements cannot be embedded in the ?: operator. It is an operator, and thus must follow all the restrictions placed on parameters to operators. ...

Finds nested conditional operator. Nested conditional operators lead code hard to understand, so they should be splited as several statement and stored in temporary varibale.

but its rvalue-ness or lvalue-ness will influence which conversion operator gets called on thervalue_probeobject. Both conversion operators do essentially the same thing: dereference the pointer to the container expression and return the result. As a side-effect, it records in the Boolean flag ...
Expressions with type bool shall not be used as operands to built-in operators other than the assignment operator =, the logical operators &&, ||, !, the equality operators == and !=, the unary & operator, and the conditional operator.
Aconditional expressionis a compound expression that contains a conditionthat is implicitly converted to typeboolin C++(operand1), an expression to be evaluated if the condition evaluates to true (operand2), and an expression to be evaluated if the condition has the value false (operand3). ...
