Recurrence relation

A recurrence relation or recursive relation is an equation that represents a function in terms of the values of its smaller inputs. Every recurrence relation T(n) is a recursive function of integer n and consists of a base case and a recursive case.

Question

100%

Solve Both parts.

1. Overload the insertion and extraction operator to take input for the lecturerData class
below. Your operator overload functions should be capable of writing statements that take
multiple inputs and display multiple outputs as below.
lecturerData L1,L2;
cin>>L1>>L2;
cout<<L1<<L2;
class dateType
{
int day,month, year;
};
class lecturerData
{
char firstName[10];
char lastName [10];
int empid;
char designation[10];
dateType DOH;
};
2. Write a program that writes and reads the class lecturerData given below in a file
in binary format. The data for the objects of the class lecturerData should be
taken from user using the overloaded insertion operator function
created above (in Q1) and after reading from file displayed using the
extraction operator function created above (in Q1) created
