Answer 1

Please find the answer below for the questions.

Which line is first line of the date structure prototype (blueprint)?

Answer: Line# 7

It has data struct prototype.

Which line is date structure declared inside another structure prototype?

Answer: Line# 21

This line has data struct declared inside student structure and we can also have line# 22

What is the structure tag which has date as a data member?

Answer: student

struct student has data as data member
