QuestionWhich of the following is not a valid variable name declaration?
Select one: a. int $\qquad$ 3a: b. int A3: c. None of the mentioned d. Int a3: $\qquad$

Studdy Solution
Both `3a` and `Int a3` are not valid variable declarations.
Since the problem asks which is *not* valid, and we found two, we must select the option that reflects this.
Since there is no "a and d" option, and "None of the mentioned" would imply they *are* valid, we can conclude that the problem has an error.
The best we can do is select **a. int $3a$** and **d.
Int a3**, and inform the teacher of the problem's error.
