"The ability to create methods with the same name that are in different classes" is known as ________.
Jlenok [28]

Answer:

Polymorphism

Explanation:

Polymorphism is the ability of an object to take multiple forms. It is an important concept of Object Oriented Programming. Polymorphism is used in Object Oriented Programming when a reference of a parent class is used to refer to a child class object. It allows to perform a single action in different ways. For example a person can possess different characteristics at the same time. A person can be a father, husband, employee or student. The same person can have different behaviors in different circumstances.

Example:

Suppose there is class Animal with a procedure sound(). This method can have different implementation for different animals. For this purpose lets take two derived classes Cow and Cat that extend the Animal class (parent/base class). Now the method sound() can be used in different ways for Cow and Cat.

public class Animal{

public void sound(){

System.out.println("Animal is making a sound");  } }

public class Cat extends Animal{

 public void sound(){

  System.out.println("Meow");     } }

The output is Meow. The same method sound() is used for cat subclass.

public class Cow extends Animal {

  public void sound(){

    cout<<"Mooo";  }}

The output is Mooo. The method sound() is used for a Cow subclass which returns the sound of Cow in output.

So the same function i.e. sound() behaves differently in different situations which shows Polymorphism.

Polymorphism has 2 types.

One is compile time polymorphism which is called overloading. In method overloading a class can have more than one functions with same name but different parameters. Methods can be overloaded by change in number or type arguments. For example overloading a function method() can take the following forms in which the name remains the same and parameters are different.

void method(int a)

void method(float a)

void method(float a, float b)

Second type is run time polymorphism which is called overriding. Method overriding is when a method declared in derived class is already present in base class. In this way derived/child class can give its own implementation to base/parent class method. Method present in base class is called overridden and that in subclass is called overriding method. The example of Animal Cow and Cat given above is an example of overriding.

a. displays the sum of all even numbers between 2 and 100 (inclusive). b. displays the sum of all squares between 1 and 100 (inc
LuckyWell [14K]

Answer:

The program required is in the explanation segment.

Explanation:

Program :

import math

# a. displays the sum of all even numbers between 2 and 100 (inclusive).

print("All even numbers from 2 to 100 inclusive ")

sum=0

i=2

while i<=100:

if i %2 ==0:

sum=sum+i

print(i,end=" ")

i=i+1

print("\nThe sum of all even numbers between 2 and 100 (inclusive) :",sum);

#b. displays the sum of all squares between 1 and 100 (inclusive).

print("\nAll squares numbers from 1 to 100 inclusive:")

i=1

sum=0

while i<=100:

print(i*i,end=" ")

i=i+1

sum=sum+(i*i)

print("\n\nThe sum of all squares between 1 and 100 (inclusive) is :",sum)

#c. displays the powers of 2 from 1 up to 256.

print("\nAll powers of 2 from 2 ** 0 to 2 ** 8:")

i=0

while True:

p=math.pow(2,i)

if p>256:

break

print("2 ** ",i," is ",int(p))

i=i+1

#d. displays the sum of all odd numbers between a and b (inclusive), where a and b are inputs

print("\nCompute the sum of all odd integers between two intgers ")

a=int(input("Enter an integer:"))

b=int(input("Enter another integer: "))

count = 0

temp=a

sum=0

while a<=b:

if a%2!=0:

print(a,end=" ")

sum=sum+a

a=a+1

print("\nThe total of the odd numbers from ", temp ," to ", b ,"is",sum)

#e.displays the sum of all odd digits of an input. (For example, if the input is 32677, the sum would be 3 + 7 + 7 = 17.)

print("\nCompute the sum of the odd digits in an integer ")

n=int(input("Enter an integer:"))

count=0

sum=0

temp=n

while n!=0:

rem = n%10

if rem%2!=0:

sum=sum+rem

count=count+1

n=int(n/10)

print("Sum of the odd digits is ",sum)

print("The total of the odd digits in ",temp," is ",count)

What happens when the programmer tries to access an array cell whose index is greater than or equal to its logical size?
just olya [345]

Answer:

When a programmer tries to access an item in an array cell whose index is greater than or equal to the array's logical size, this data element or item is garbage. This means that currently, the item is not the part of the program's useful data. Garbage contains objects or data which will not be used by a program running on it. So the value returned could be either of the two:

  • Value would be an arbitrary or random number if it is an array of numbers. Arbitrary means that the value is not predefined or specified in advance.
  • Value returned would be null if it is an array of objects.
