Answer:
Expression for the above problem in python language:
userNum=int(input("Enter the value of user_Num")) #it is used to take input.
if(userNum>(-10)): #if statement
print("The value of the userNum is greator")
elif(userNum==(-10)): #elif statement
print("The value of the userNum is equal to -10")
else: #else statement.
print("The value of the userNum is small")
Output:
- If the user input is (-10), it will print equal.
- If the user input 10, it will print greator message.
Explanation:
- The above program or expression is in python language, where the first line is used to render a message to the user take the input and store it into a userNUM variable.
- Then the second line is used to check the user num value to be greater with the help of if statement.
- Then the third statement is used to check the user num value to be equal with the help of elif statement.
- Then the else statement will execute when the if and the elif statement will not true.
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.
