We would like to create a program that asks the user how many family members they have and what are their names/roles (like: Jeff or Father). Then, the user is going to insert the family members' ages one by one.
If the user inserts wrong numbers such as "-5" for one of the family members we need to eliminate the inserted number and ask the user to re-insert it. If the user inserts someone's age more than two times wrongly, our program recognizes the user as a robot and spam and will not allow the user to continue anymore.

Finally, the user is going to print the family members in a sorted way from the oldest family member to the youngest one with their names and their ages. answer in c++

Write a C++ program that takes a vector (with only positive integers) and prints the number of elements in it. [The user will insert any number of elements.]

A publication company that markets both book and audiocassets versions of its works.
create a class called publication that stores the title (a string) and price (type float) of
publication. This class includes getdata() and showdata() member functions for input and output
data members. This class also includes a pure virtual member function “ISOversize()”. From this
class derive two classes: Book, which has a page count (type int) and Tape class which has a
playing time in minutes (type float). Each of these two derived classes should override the base
class member functions. Let’s say that a book with more than 500 pages, or a tape with a
playing time longer than 90 minutes, is considered oversize. You can access member functions
from main() and display the string “Oversize” for oversized books and tapes when you display
their data.
Write a main() program that creates an array of pointers to publication. In a loop, ask the user
for data about a particular book OR tape.

Problem: Meal gift card. Your favorite campus restaurant sells meals for $13 each meal. The restaurant requires members to pre-pay any amount of money they wish, and then purchase as many meals accordingly. You are required to write a java program correctly that would ask the user for the amount that they will pay, then display a message indicating how many meals that user will be able to purchase as well as how much funds will remain in the gift card after that. 

Using exactly 1 integer constant, 3 integer variables, and 1 Scanner variable make sure to fulfill the following points:

1. Declare the following constant integer: PRICE and set it to 13.

2. Declare 3 unassigned integer variables amount, meals, balance.

3. Declare 1 Scanner variable that will record keyboard inputs.

4. Prompt the user in the console for the amount that they will pay and assign to amount (use same format and wording as in the sample outputs below). Assume the user will enter an integer value.

5. Assign to meals the result of amount / PRICE.

6. Assign to balance the result of amount % PRICE.

7. Output to the console a blank line followed by the message

With $ you can buy meals and will have a balance of $.

Where ,and are the values stored in the corresponding variables. 

Based on the previous specifications your program should look and behave exactly as displayed in the cases below. Your
program should work for any double values entered by the user, not just the ones in the sample.
Note that ◦ symbol indicates a space and ↵ is a new line character. All words except for user input (in blue) must be exactly as indicated in the sample. Any extra “spaces” and/or “new lines” will be graded a wrong answer.

Note 1: You are to expect a perfect user who always enters integer numbers., do not verify the validity of user input.
Note 2: The use of libraries other than java.util.Scanner is prohibited. Your program must work for any integer values entered, not just the ones in the samples above.
Note 3: Final thought, remember that your solution is space-sensitive and fulfill the above instructions carefully and
precisely.
