Polymorphism means (Points : 2) many forms

Pavel [41]

Answer:

many forms

Explanation:

Polymorphism is a construct in object oriented programming which means multiple forms.For example: Suppose I have a function which performs the add operation on two integers and another function with the same name which concatenates 2 given strings:

int add ( int a, int b);

string add ( string a , string b)

The two functions represent polymorphic forms of the add function. The function to be invoked at runtime is determined by the runtime argument type.

For example , add (2,3) will invoke int add ( int a, int b);

Similarly, add("hello","world") will invoke string add ( string a , string b);

Answer:

Explanation:

//Guitar.java

import java.awt.Color;

import java.lang.reflect.Field;

import java.util.Random;

public class Guitar

/**

* these two fields are used to generate random note and duration

static char[] validNotes = 'A', 'B', 'C', 'D', 'E', 'F', 'G' ;

static double[] validDuration = 0.25, 0.5, 1, 2, 4 ;

/**

* basic guitar attributes

private int numStrings;

private double guitarLength;

private String guitarManufacturer;

private Color guitarColor;

public Guitar()

/**

* default constructor

numStrings = 6;

guitarLength = 28.2;

guitarManufacturer = Gibson;

guitarColor = Color.RED;

public Guitar(int numStrings, double guitarLength,

String guitarManufacturer, Color guitarColor)

/**

* parameterized constructor

this.numStrings = numStrings;

this.guitarLength = guitarLength;

this.guitarManufacturer = guitarManufacturer;

this.guitarColor = guitarColor;

/**

* required getters and setters

Write a C++ programthat reads in the side of a square and prints out a pattern on$

AnnZ [28]

Answer:

#include<iostream>

using namespace std;

//main function

int main(){

//initialize the variables

int side;

//print the message

cout<<"Please enter the side of square: ";

cin>>side; //read the vale and store in the variable.

// for loop

for(int i=1;i<=side;i++){ //lop for rows

for(int j=1;j<=side;j++){ //loop for column

cout<<"$"; //print the '*'

}

cout<<endl;

}

Explanation:

Create the main function and declare the variable side.

print the message on the screen for the user and then store value enter by the user on the variable side.

take the nested for loop for print the pattern.

nested for loop means, loop inside another loop it is used for print the pattern having rows and columns.

the first loop updates the row number and the second the loop print the character '$' in the column-wise.

in the code,

if i = 1, for loop check the condition 1 <= 5 if the value of side is assume 5.

condition is true and the program moves to the second for loop and starts to print the character '$' five times after that, print the new line.

then, the above process repeat for different rows and finally, we get the pattern in square shape.
