[amp_mcq option1=”(* )” option2=”(symbolp )” option3=”(nonnumeric )” option4=”(constantp ) E. None of the above” correct=”option2″]
The correct answer is B. (symbolp ).
The function (symbolp ) returns t if the object is a symbol. A symbol is a Lisp object that represents a name. Symbols are used to represent variables, functions, and constants.
The function (* ) returns the product of the object and itself. The function (nonnumeric ) returns t if the object is not a number. The function (constantp ) returns t if the object is a constant.
