Answer:
I will code in JAVA.
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
boolean tallEnough;
boolean oldEnough;
Scanner input = new Scanner(System.in);
tallEnough = input.nextBoolean();<em> //wait the input for tallEnough</em>
oldEnough = input.nextBoolean(); <em>//wait the input for OldEnough</em>
if(tallEnough && oldEnough){
System.out.print(true);
} else {
System.out.print(false);
}
}
}
Explanation:
First, to accept user inputs you have to import the class Scanner. Then declare both variables before allowing the user to set input values for both boolean variables.
In the if-else statement checks if both variables are true, then prints true. Another case prints always false.
Answer: There are many different types of user interfaces. To decide on the user interface depends entirely on the requirement of the client.
Explanation:
There are different types of interfaces such as command line user interface, graphical user interface, menu based, form based. Therefore to choose among them it depend on the requirement specified by a client. Mostly nowadays GUI is used. to maintain records form based is preferred. For system software CUI is better due to decrease its pressure on the processor. Networking is also both GUI and CUI. So it depend mainly on the type of application developed , client requirements, power consumption based on its dependence on processor power.
You’d probably use a USB Flash Drive.
There are inhabited areas INSIDE the Amazon Rainforest. Many primitive tribes with little to no contact of the outside world live in remote areas of the rainforest, but the closest major city to the rainforest (also inside) is Manaus, Brazil.
Answer:
Encapsulation:-It is the binding of the data and functions so that they works as one unit.
Inheritance:-When one class acquires the property of another class it is called inheritance.
Polymorphism :-It generally means more than one form
Explanation:
Encapsulation:- class is an example of encapsulation it can hold different data types and functions in a single container called class.
class Name{
public:
string first_name;
string last_name;
void Display()
{
cout<<first_name<<" "<<last_name<<endl;
}
};
Inheritance:-The property of a class acquiring the properties of another class is called inheritance.
Now we will inherit the above defined class.
class person: public Name
{
public:
char gender;
int age;
void Display()
{
cout<<first_name<<" "<<last_name<<gender<<age<<endl;
}
};
int main()
{
Name n;
person p;
n.Display();
p.Display();
}
Polymorphism- There are two types of polymorphism:-
1.Run time polymorphism=The values are decided at run time.
2.Compile time polymorphism=The values are decided at compile time.
Example:-In the above example we have function Display() in both the classes.This is an example of compile-time polymorphism. We are deciding at the time of compilation which display to use.
