How can I write this code ( sorry I can't understand)

Assignment: Write a program according to the following condition using the structure:
Display information about employees whose salaries are above average and are less than 30 years old.
Structure fields: Last name, First name, Job title, Salary, Date of birth

build your structure, as described.
make a container of those. perhaps it would help if the container used can be sorted easily?
populate the container. while doing this, you may calculate the average to save effort, or do it stand alone later (better design of do one thing in one function, but less efficient, design and efficiency are often at odds)
write your display code... your data is sorted now by the salary, so you find the first one that is above average, start there and iterate all the rest of the container. Print the ones where age is < 30.
you can either compute age from DOB or figure out what DOB is < 30 and work off DOB directly. Either one works.

Since I am a beginner also I tried this out with only a few people.
