The post office offers subscriptions to two kinds of Periodicals: magazines and newspapers.
The framework of the following base classes is given
class Periodical
{

}
Taking periodic as the base class, we construct magazine and newspaper classes.
Generate the above class and write the main function, which requires that there is a base class periodic pointer array in the main function, with no more than 10 array elements.
Periodical *pp[10];
According to the input information, the main function establishes the magazine and newspaperclass objects. For magazine, it gives the number of subscription periods and the price of each period. For newspaperit gives the number of subscription weeks, weekly publishing times and the price of each period.

When output, print the name and charge of each journal in turn (one decimal place after decimal point).
