You can present your presentation on the topic of member function in c++ with very easy examples.

2. The functions declared inside the class are knows as
Member Function and works on the data members of the
class. The definition of member functions can be inside or
outside the class.
class student{
public:
void myStudent()
{
………………
statements
……………….
}
};
Class keyword
Member function
Class name

3. If the member function is defined inside the
class definition it can be defined directly, but if
its defined outside the class, then we have to
use the scope resolution :: operator along with
class name along with function name.
Member function
prototype declaration

4. Similar to accessing a data member in the
class, we can also access the public
member functions through the class object
using the dot operator (.).
