If you want to print on a page you can use

document.write();

If you want to write in console then there are multiple options

console.log() - to log information

console.error();- to log errors

console.warn(); - to log warning message

If you want to popup some information the you can use -

alert(message);

there are also various options present in alert.

print() essentially just calls up the native print dialog for a given window.

But as you're are thinking, it will work on any window or (i)frame.

thus if you write content to a frame, you can then call this to print it.

window.frameName.print();

note the only drawback (and its a big one), is that this calls up the print dialog... not the print preview window... thus the user doesn't really get a chance to see what they are printing and/or scale it to fit their printer/paper.

I personally wish that all browsers would implement the following to handle the above issue.

window.printPreview();

Hope this will help !!!

QUESTION

Lady_Fox [76]

Answer:

Explanation:

#include <iostream>

using namespace std;

int main ()

{

int responses[30],count[6];

int score = 0;

string resp = " ";

for (int i = 0; i < 30; i++)

{

responses[i] = 0;

}

for (int i = 0; i < 6; i++)

{

count[i,1]=0;

count[i,2]=0;

count[i,0]=0;

}

while ((resp != "Y") && (resp != "y"))

{

for (int i = 0; i < 30; i++)

{

while ((score > 5) || (score < 1))

{

cout << "Student " << (i+1)<< " please enter a value (1-5):";

cin >> score;

}

responses[i] = score;

if((score > 5)||(score<1))

{

if(score==1) count[1]++;

if(score==2) count[2]++;

if(score==3) count[3]++;

if(score==4) count[4]++;

if(score==5) count[5]++;

}

score = 0;

}

cout<< "Response Frequency Percentage"<<endl;;

cout<< " 1 "<<count[1]<<" "<<(count[1]/30)<<"%"<<endl;

cout<< " 2 "<<count[2]<<" "<<(count[2]/30)<<"%"<<endl;

cout<< " 3 "<<count[3]<<" "<<(count[3]/30)<<"%"<<endl;

cout<< " 4 "<<count[4]<<" "<<(count[4]/30)<<"%"<<endl;

cout<< " 5 "<<count[5]<<" "<<(count[5]/30)<<"%"<<endl;

cout<< "Do you want to exit? Press Y to exit any other key to continue: ";

cin>> resp;

}

return 0;

What is the difference between password protection and encryption? please answer quick, i cant pass this test for the life of me

sergiy2304 [10]

Answer:Password protection is like locking something in a safe-deposit. It means no one can get to the locked content without knowing the right combination. This method is used on separate documents, folders, and other data the computer's user may want to protect from other people who might have access to the device. The problem is, if someone interested in such content obtains the password or finds a way to open it without it, the content might be revealed despite the owner's efforts to keep it hidden. Unfortunately, there are a lot of ways hackers could obtain the password or hack in without it. For example, it could be obtained with the help of malware, or it might be guessed if the user chooses a weak password. Not to mention, when it comes to PDF documents, the passwords placed on them can be removed using the CMD window or specific.

Password encryption is a step up from password protection. The term can be a tad confusing because, in fact, you cannot encrypt the password itself. Instead, by setting up "password encryption" you are creating a password AND encrypting the contents of the file. In our example (see instructions below), the contents of the user's PDF document are not only password protected, but also encrypted. It is a process during which the content one wishes to keep secret is altered to make it unrecognizable. For example, if it is a text document, letters of each word might be shuffled with additional characters so the words would no longer make any sense. The reverse process is only available if the person who wants to decrypt this data can provide a specific decryption key or a password. In other words, even if the password is removed no one could read the hidden content as it still would need to be decrypted. Of course, it is important to realize you might be unable to retrieve it too if you lose the decryption key, aka, the password.

Write the logical Expression and Draw the Truth table for the <br> following questions

Alja [10]

The logical expressions are

(X NOR Y ) OR Z ⇒ $(\bar X \bar + \bar Y) + Z$
(A NAND B) AND NOT C ⇒ $(\bar A \bar \cdot\bar B) \cdot \bar C$

<h3>How to determine the logical expressions?</h3>

<u>Logical expression 1</u>

X and Y are linked by the NOR gate.

So, we have:

X NOR Y

The X NOR Y is linked to Z by the OR gate.

So, we have:

(X NOR Y) OR Z

Hence, the logical expression is (X NOR Y ) OR Z ⇒ $(\bar X \bar + \bar Y) + Z$

<u>Logical expression 2</u>

A and B are linked by the NAND gate.

So, we have:

A NAND B

The A NAND B is linked to C by the AND gate.

So, we have:

(A NAND B) AND C

Hence, the logical expression is (A NAND B) AND NOT C ⇒ $(\bar A \bar \cdot\bar B) \cdot \bar C$

See attachment for the truth tables
