Write JavaScript code to declare a variable of the name favoriteColor

Zinaida [17]

Answer:

Variables are used to store values (name = "John") or expressions (sum = x + y).

Declare Variables in JavaScript

Before using a variable, you first need to declare it. You have to use the keyword var to declare a variable like this:

var name;

Assign a Value to the Variable

You can assign a value to the variable either while declaring the variable or after declaring the variable.

var name = "John";

OR

var name;

name = "John";

The __________ statement allows you to check for

sweet [91]

Answer:

B) nested if...else

Explanation:

In Computer programming, there are four (4) main types of statements used in the decision-making process and these are;

I. If statement.

II. If....else statement.

III. Else.....if statement.

IV. Nested if...else statement.

The nested if...else statement allows you to check for multiple test expressions and execute different codes for more than two conditions. It uses the other three (3) statements in its decision-making process.

However, only the first test expression would be executed when it is true and then the program is terminated. Otherwise, the program would continue to run until it gets to the breaking point (else statement) and then terminates.

Write Album's PrintSongsShorterThan() to print all the songs from the album shorter than the value of the parameter songDuration

lidiya [134]

Answer:

kindly check explainations for code

Explanation:

Check below for program code.

#include <iostream>

#include <string>

#include <vector>

using namespace std;

class Song

{

public:

void SetNameAndDuration(string songName, int songDuration)

{

name = songName;

duration = songDuration;

}

void PrintSong() const

{

cout << name << " - " << duration << endl;

}

string GetName() const { return name; }

int GetDuration() const { return duration; }

private:

string name;

int duration;

};

class Album

{

public:

void SetName(string albumName) { name = albumName; }

void InputSongs();

void PrintName() const { cout << name << endl; }

void PrintSongsShorterThan(int songDuration) const;

private:

string name;

vector<Song> albumSongs;

};

void Album::InputSongs()

{

Song currSong;

string currName;

int currDuration;

cin >> currName;

while (currName != "quit")

{

cin >> currDuration;

currSong.SetNameAndDuration(currName, currDuration);

albumSongs.push_back(currSong);

cin >> currName;

}

void Album::PrintSongsShorterThan(int songDuration) const

{

unsigned int i;

Song currSong;

cout << "Songs shorter than " << songDuration << " seconds:" << endl;

/* Your code goes here */

for(int i=0; i<albumSongs.size(); i++){

currSong = albumSongs.at(i);

if(currSong.GetDuration()<songDuration){

currSong.PrintSong();

}

int main()

{

Album musicAlbum;

string albumName;

getline(cin, albumName);

musicAlbum.SetName(albumName);

musicAlbum.InputSongs();

musicAlbum.PrintName();

musicAlbum.PrintSongsShorterThan(210);

return 0;

}

1.What is the output of the following program? [10 Marks]namespace ConsoleApp1{class Program{static void Main(string[] args){int

Nataliya [291]

The program outputs the following rectangular array:

0 0 0 0

0 1 2 3

0 2 4 6

0 3 6 9

0 4 8 12

This is the correctly formatted C# program:

namespace ConsoleApp1{

class Program

{

static void Main(string[] args)

{

int i, j; // declare index variables used to iterate over the array A

int [,] A = new int[5,5]; // create a 5 by 5 array

/* Iterate over the array with the index variables i and j

and initialize each location A[i, j] with the product

of i and j. */

for (i = 0; i < 5; ++i)

{

for (j = 0; j < 4; ++j)

{

A[i, j] = i*j;

}

/* Iterate over the array again. This time, swap locations

A[i, j] with A[j, i] */

for (i = 0; i < 5; ++i)

{

for (j = 0; j < 4; ++j)

{

if (i < 5)

{

A[j, i] = A[i, j];

}

else

break;

// display the current location A[i, j]

Console.Write(A[i, j] + " ");

}

/* print a newline to prepare for the next line of printing

which corresponds to the next column i */

Console.WriteLine();

// pause and wait for user keypress before continuing

Console.ReadLine();

}

When executed, this program simply prints a rectangular array like so;

0 0 0 0

0 1 2 3

0 2 4 6

0 3 6 9

0 4 8 12
