Which is TRUE about web-based application software? It is stored completely on a web server instead of your hard drive. It is in

mote1985 [20]

It is TRUE that a web-based application is stored completely on a web server instead of your hard drive.

Explanation:

Web apps can be accessed over the internet over a HTTP network. These applications are hosted on a remote server and can be accessed easily via a browser. We can only go as far downloading them to our desktop but we cannot make adjustments to them after we have downloaded them. All changes are made on a web browser.

Its mechanism is so easy. It is based on client-server architecture. The client will interact with the application by inputting data. The server, on the other hand, will receive, store, and help in retrieving the result. Accessing applications such as Word online or Spreadsheets online is the best example of how web apps can be accessed over the internet.

Create a C++ program that declares, initializes, and outputs the values contained in a two-dimensional array

Kazeer [188]

Answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

// main function

int main()

{

// variables

int r_size,c_size;

cout<<"enter the number of row:";

// read the value of row

cin>>r_size;

cout<<"enter the number of column:";

// read the value of column

cin>>c_size;

// create a 2-d array

int arr[r_size][c_size];

// read the value of array

cout<<"enter the elements of array:"<<endl;

for(int x=0;x<r_size;x++)

{

for(int y=0;y<c_size;y++)

{

cin>>arr[x][y];

}

cout<<"elements of the array are:"<<endl;

// print the array

for(int a=0;a<r_size;a++)

{

for(int b=0;b<c_size;b++)

{

cout<<arr[a][b]<<" ";

}

cout<<endl;

}

return 0;

}

Explanation:

Here we have demonstrate a 2- dimensional array. In which, how to read the elements and how to print elements of array.Read the value of row and column from user.Create a 2-d array of size r_sizexc_size. then read the elements of array either row wise or column wise. Then print the elements.To print the elements, we can go either row wise or column.

Output:

enter the number of row:2

enter the number of column:3

enter the elements of array:

1 2 3

2 3 4

elements of the array are:

1 2 3

2 3 4

Draw the flowchart and pseudocode for a program allowing the user to enter a value for one edge of a cube(A box-shaped solid obj

horsena [70]

Answer:

The flowchart, pseudocode and python program all have the same objective.

The flowchart is designed using draw.io (See attachment)

Pseudocode begins here:

1. Start

2. Input Length

3. Area1 = Length * Length

4. Area2 = 6 * Area1

5. Volume = Area1 * Length

6. Print Length

7. Print Area1

8. Print Area2

9. Print Volume

10. Stop

Python Program begins here:

#Prompt user for input

length = float(input("Length of the edge: "))

#Calculate the area of a side

Area1 = length * length

#Calculate the area of the cube

Area2 = 6 * Area1

#Calculate the volume

Volume = Area1 * length

print("Length: "+str(length))

print("Area of a side: "+str(Area1))

print("Area of the cube: "+str(Area2))

print("Volume: "+str(Volume))

Explanation:

The flowchart , pseudocode and python program start by requesting for user input;

This user input is saved in variable length

The surface area of a face is calculated by length * length and saved in Area1; i.e. Area1 = length * length

The surface area of the cube is calculated by 6 * Area1 and saved in Area2. i.e. Area2 = 6 * Area1 = 6 * length * length

The volume of the cube is calculated by Area1 * length and saved in volume. i.e. Volume = Area1 * length = length * length * length

After the surface area of one side of the cube

, the surface area of the whole cube and the volume of the cube are calculated; the program then prints the user input (length) and each of the calculated parameters.

import java.io.FileWriter;

import java.io.InputStreamReader;

import java.util.Scanner;

public class file

{

public static void main(String []args)

{

try

{

System.out.print("Type a file name: ");

//declare scanner for keyboard input

Scanner reader = new Scanner(System.in);

//scan the input file name

String infilename=reader.nextLine();

//define file stream

FileInputStream fstream = new FileInputStream(infilename);

DataInputStream in = new DataInputStream(fstream);

//define the buffer reader

BufferedReader br = new BufferedReader(new InputStreamReader(in));

String outfilename = "output.txt";

FileWriter fileWriter = new FileWriter(outfilename);

//declare buffer writer for file write

BufferedWriter bufferedWriter = new BufferedWriter(fileWriter);

String strLine,filename;

int status = 0;

int i=0;

//read lines one by one from input file

while ((strLine = br.readLine()) != null)

{

String temp="";

//for each character in a line

for(int k=0;k<strLine.length();k++)

{

char c;

c=strLine.charAt(k);

//if the character is uppercase

if(Character.isUpperCase(c))

//make the character lowercase and append it to the output line

temp +=Character.toLowerCase(c);

else

//character is not lowercase. append to the output line without changing it

temp += c;

}

//write the line to the file

bufferedWriter.write(temp+"\n");

}

//close the input file

in.close();

//close the output file

bufferedWriter.close();

}

catch (Exception e)

{

//System.err.println("Error: " + e.getMessage());

}
