The set and get functions are analogous to the accessor and mutator functions of C++. They are used in place of modifying a class member directly inside an object and making it public. An accessor function must be invoked in order to gain access to a private object member.
int mVal = winarr[0].getWidth();
for(int i = 1; i < winarrsize; i++)
{
if(winarr[i].getWidth() > mxVal)
mVal = winarr[i].getWidth();
}
cout << "The widest width is: "
<< mVal << endl;
By using encapsulation, a programmer can specify the labels for the data members and functions as well as whether or not other classes can access them. When data members are marked as "private," member functions of other classes cannot access or modify them which allows members access to these private data.
For a member such as Level, a function like GetLevel() returns the value of the member, while a function like SetLevel() gives it a value.
