Creation of a class

Implement class with two fields (Field 1, Field 2) and four methods:

- two constructors for initialization of object (with parameters and without parameters);

- function of obtaining information string about object;

- function of calculation some given characteristic of object.

In main program create an object using values from Edit components or constant values and write the information about the object to Memo.
