// base class
class Animal {
public:
void eat() {
cout << "I can eat!" << endl;
}
void sleep() {
cout << "I can sleep!" << endl;
}
};
// derived class
class Dog : public Animal {
public:
void bark() {
cout << "I can bark! Woof woof!!" << endl;
}
};
int main() {
// Create object of the Dog class
Dog dog1;
// Calling members of the base class
dog1.eat();
dog1.sleep();
// Calling member of the derived class
dog1.bark();
return 0;
}

Answer: Detailed
Explanation:
SDLC consist of 7 phases. They are:
1. Planning.
2. System analysis and requirement
3. Design:
4. Coding:
5. Testing:
6. Installation
7. Maintenance
Here we are talking of the third phase. In this phase it is the design phase which consist of high and low level design. Here the preliminary design is included in high level design where it describes the required hardware, software, network capabilities and the modelling of the interface. However the detailed design in low level design will implement the coding and will finding of any errors in the implemented design as described by the preliminary design.
