inheritance
it is used to define relationship between two class,
which a child class occurs all the properties and behaviours of a parent class.
Provides code reusability.
Ex: in my framework I have a TestBase class which I store
all my reusable code and methods. My test execution classes and
elements classes will extend the TestBase in order to reuse the code.inheritance
class left {
public:
void foo();
};
class right {
public:
void foo();
};
class bottom : public left, public right {
public:
void foo()
{
//base::foo();// ambiguous
left::foo();
right::foo();
// and when foo() is not called for 'this':
bottom b;
b.left::foo(); // calls b.foo() from 'left'
b.right::foo(); // call b.foo() from 'right'
}
