Using base in a derived class invokes the base class's corresponding method.
For example, something like:
class Shape{
public void print(){printf("Generic shape");
...
}
class Triangle:Shape{
public void print(){printf("Triangle");
...
}
int main()
{
Triangle x;
x.print(); // Should print "Triangle"
x.base.print(); // Should print "Generic shape"
return 0;
}
