/*Write a C++ program having class time with data members: hr, 
min and sec. Define following member functions. 
1) getdata() to enter hour, minute and second values 
2) putdata() to print the time in the format 11:59:59 
3) default constructor 
4) parameterized constructor 
 Use 52 as default value for sec in parameterized constructor.
5) copy constructor 
6) Destructor. 
Use the concepts of default constructor, parameterized constructor, 
Copy constructor, constructor with default arguments and 
destructor.
