D
answer
A
Answer is D
because ‘:’ must be there after the variable need to change
The correct answer is B.
there is no : before formatting a data so D cannot be the right answer.
“:” helps to read immediate value after spaces. Ans is D
The true answer is D not A.
The reason:
When you are reading an external file you must wirte (colon 🙂 and the correct format.
The answer D, is right.
Try it on sas 😉
Both B & D are correct for given input data.
But D will not be correct if there is birthday value as “10 20 84”, Hence B is the best answer.
