The ________ operator is particularly useful when working with complex template types for which it’s often difficult to provide, or even determine, the proper type declaration. Rather than trying to write a complex type declaration, for example, that represents the return type of a function, you can place in the parentheses of this operator an expression that returns the complex type and let the compiler “figure it out.”
a. infer_type
b. decltype
c. determine_type
d. static_assert
