/* Q1.Assume a member function , get_num(), with return vlue of type int is declared inside a class called Calcuator.
Write a typical class specifier and declare the member function. Also write the definition of the function outside the class
specifier.

Add a private data member called number of type int to the class Calculator in Q1.
Write a constructor that initialies number to 0.
Assume the constructor is defined within the class spcifier.
