They can be used to just copy/paste e-mailed information without writing down on a paper and losing valuable time. This is one example.
Answer:
#include<iostream>
int main()
{
int count=0;
int so_phan_tu;
std::cout << "nhap so phan tu : \n";
std::cin >> so_phan_tu;
int* A = new int[so_phan_tu];
std::cout << "nhap cac phan tu : \n";
for (int i = 0; i < so_phan_tu; i++)
{
std::cin >> A[i];
if (A[i] % 5 == 0)
{
count++;
}
}
std::cout << so_phan_tu - count;
system("pause");
return 0;
}

Explanation:
This is about identifiers in a record referring to other records.
You can have many to one, one to one, many to many.
E.g., if you have two tables, Authors and Books, then a book record could have a reference to an author record. Since an author can write many books, this would be a many-to-one relationship.
Banded rows indicate that there are different formatting for odd and even rows.
