Answer:
The function definition for this question can be given as:
Function Definition:
bool isSenior(int x ) //function
{
//function body Or function definition.
//conditional statement
//if statement
if (x >=65)
{
return true; //return value true.
}
else //else statement
{
return false; //return value false.
}
}
Explanation:
In the above function definition firstly we define a function that isSenior. This function return Boolean value that is true or false in this function we pass the value as the parameter in that function we use the if statement that check the pass value is greater then equal to 65. If the condition is true it return true.else it will return false.
Answer:
you cannot obtain a new copy of the keys that you have stored on Hardware Security Module, because they are lost forever and a new copy cannot be obtained if a copy is not kept somewhere.
Explanation:
Hardware Security Module (CloudHSM) is a cloud-based hardware security module (HSM) that provides the user the opportunity to create and utilize your own encryption keys on the AWS Cloud. It is a fully managed service that takes care of time-consuming administrative activities such as software patching, backups, hardware provisioning, and high-availability for the user.
One of the key elements of the Hardware Security Module (CloudHSM) is that a copy of the keys stored must be kept somewhere because if keys are lost, they are lost forever and a new copy cannot be obtained if a copy is not kept.
Therefore, you cannot obtain a new copy of the keys that you have stored on Hardware Security Module, because they are lost forever and a new copy cannot be obtained if a copy is not kept somewhere.
Answer:
The advantage for the above condition is as follows:-
Explanation:
- If a user creates a defined constant variable and assigns a value on its and then uses that variable instead of the value, then it will a great advantage.
- It is because when there is a needs to change the value of that variable, then it can be done when the user changes the value in one place. There is no needs to change the vale in multiple places.
- But if there is a value in multiple places instead of a variable and there is no constant variable, then the user needs to change the value in multiple places.
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.
