Final answer:
Since all other options label actual operators, option a) all of above" is the answer because it does not represent an operator.
Step-by-step explanation:
To identify which option is not an operator in the C programming language.
The options are:
- a. all of above
- b. ~ (Bitwise NOT operator)
- c. . (Dot operator)
- d. sizeof() (Sizeof operator)
- e. none of these
In C, option b (~) is the bitwise NOT operator, option c (.) is used to access members of a structure, and option d (sizeof()) is an operator that returns the size of a datatype or variable.
Therefore, the options provided in b, c, and d are indeed operators in C.
However, option a (all of above) does not represent a specific operator, and it is actually a phrase related to the question’s answer choices.
Since all other options label actual operators, option a is the answer because it does not represent an operator.
