C++

Implementing an overloaded class in an STL List

Modify the Person class to be overloaded for >, <, =, ==.

Designate ostream as a friend to Person.

Now use the STL List and use Person as the template argument.

Documentation on STL List can be found at:

http://www.cplusplus.com/reference/list/list/

code with a good overload should produce these results:

Test of Person in the STL List

Harry Potter 934-888-2323 != Hermione Granger 444-678-8899

Entry Sequence Order

Harry Potter 934-888-2323

Hermione Granger 444-678-8899

Ronald Weasley 788-909-4566

Luna Lovegood 230-675-7811

Sorted Order

Hermione Granger 444-678-8899

Luna Lovegood 230-675-7811

Harry Potter 934-888-2323

Ronald Weasley 788-909-4566

Note: Designate ostream as a friend to Person class

Use the Person class for the template of the STL List
