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.
Answer: Input is the answer.
You should or must stop 50 feet away from it.
Answer: b) Standardizing how the process is completed
Explanation:
Occurrence of error in a process can be due to several reason like human error,equipmental error, qualitative error etc.It includes internal as well as external factor.To eliminate the occurrence of fault in process, it is better to follow standard and systematic working in uniform way so that any kind of manipulation and modification does not lead to error.
- Other options are not appropriate because trying harder will not correct chances of fault rather it will only waste the efforts.Not depending on technology is also not the solution to gain accuracy in process.
- Thus, the correct option is option(b).
