Function overriding is a feature in C++ that allows a derived class to provide a different implementation of a function that is already defined in its base class. It allows you to redefine the behavior of a function in the derived class, providing specialization or customization based on the derived class's specific requirements.
To override a function in C++, the following conditions must be met:
1. Inheritance: The derived class must inherit from the base class.
2. Function Signature: The function in the derived class must have the same name, return type, and parameter list (including the constness) as the function in the base class.
Example:
class Parent
{
public:
void Print()
{
statements;
}
};
class Child : public Parent
{
public:
void Print()
{
statements;
}
};
int main()
{
Child Child_Derived;
Child_Derived.Print();
return 0;
}
