While the zyLab platform can be used without training, a bit of training may help some students avoid common issues.
The assignment is to get an integer from input, and output that integer squared, ending with newline. (Note: This assignment is configured to have students programming directly in the zyBook. Instructors may instead require students to upload a file). Below is a program that's been nearly completed for you.
Click "Run program". The output is wrong. Sometimes a program lacking input will produce wrong output (as in this case), or no output. Remember to always pre-enter needed input.
Type 2 in the input box, then click "Run program", and note the output is 4.
Type 3 in the input box instead, run, and note the output is 6.
When students are done developing their program, they can submit the program for automated grading.
Click the "Submit mode" tab
Click "Submit for grading".
The first test case failed (as did all test cases, but focus on the first test case first). The highlighted arrow symbol means an ending newline was expected but is missing from your program's output.
Matching output exactly, even whitespace, is often required. Change the program to output an ending newline.
Click on "Develop mode", and change the output statement to output a newline: cout << userNumSquared << endl;. Type 2 in the input box and run.
Click on "Submit mode", click "Submit for grading", and observe that now the first test case passes and 1 point was earned.
The last two test cases failed, due to a bug, yielding only 1 of 3 possible points. Fix that bug.
Click on "Develop mode", change the program to use * rather than +, and try running with input 2 (output is 4) and 3 (output is now 9, not 6 as before).
Click on "Submit mode" again, and click "Submit for grading". Observe that all test cases are passed, and you've earned 3 of 3 points.
Answer:
Change line 10 to:
userNumSquared = userNum * userNum;
Change line 11 to:
cout << userNumSquared<<endl;
Explanation:
Though the question is a bit lengthy but the requirements are not clearly stated. However, I'm able to pick up the following points.
Print the square of the inputted numberPrint the squared number with a new lineTo do this, we simply modify the affected lines which are lines 10 and 11.
The plus sign on line 10 will be modified to multiplication
i.e.
userNumSquared = userNum * userNum;
And line 11 will be modified to:
cout << userNumSquared<<endl;
Every other line of the program is okay and do not need to be modified

Explain the complement of a number along with the complements of the binary and decimal number systems.why is the complement method important for a computer system?
olha so olha la que bacana bonito
The complement method are the digital circuits, are the subtracting and the addition was the faster in the method. The binary system was the based on the bits are the computer language.
What is computer?
Computer is the name for the electrical device. In 1822, Charles Babbage created the first computer. The work of input, processing, and output was completed by the computer. Hardware and software both run on a computer. The information is input into the computer, which subsequently generates results.
The term “binary” refers to the smallest and minimum two-digit number stored on a computer device. The smallest binary codes are zero (0) and one (1). The use of storing numbers easily. The computer only understands the binary language. The binary is converted into the number system as a human language. The complement method are the digital circuits the addition and the subtracting was the easily.
As a result, the complement method is the digital circuits are the subtracting to the binary system was the based on the bits are the computer language.

#SPJ2
Binary is a base-2 number system instead of the decimal (base-10) system we are familiar with. Write a recursive function PrintInBinary(int num) that prints the binary representation for a given integer. For example, calling PrintInBinary(5) would print 101. Your function may assume the integer parameter is non-negative. The recursive insight for this problem is to realize you can identify the least significant binary digit by using the modulus operator with value 2. For example, given the integer 35, mod by 2 tells you that the last binary digit must be 1 (i.e. this number is odd), and division by 2 gives you the remaining portion of the integer (17). What 's the right way to handle the remaining portion
Answer:
In C++:
int PrintInBinary(int num){
if (num == 0)
return 0;
else
return (num % 2 + 10 * PrintInBinary(num / 2));
}
Explanation:
This defines the PrintInBinary function
int PrintInBinary(int num){
This returns 0 is num is 0 or num has been reduced to 0
if (num == 0)
return 0;
If otherwise, see below for further explanation
else
return (num % 2 + 10 * PrintInBinary(num / 2));
}
----------------------------------------------------------------------------------------
num % 2 + 10 * PrintInBinary(num / 2)
The above can be split into:
num % 2 and + 10 * PrintInBinary(num / 2)
Assume num is 35.
num % 2 = 1
10 * PrintInBinary(num / 2) => 10 * PrintInBinary(17)
17 will be passed to the function (recursively).
This process will continue until num is 0

You should write the client so that it sends 10 ping requests to the server, separated by approximately one second. Each message contains a payload of data that includes the keyword PING, a sequence number, and a timestamp. After sending each packet, the client waits up to one second to receive a reply. If one second goes by without a reply from the server, then the client assumes that its packet or the server's reply packet has been lost in the network.Hint: Cut and paste PingServer, rename the code PingClient, and then modify the code. The two programs follow very similar process.You should write the client so that it starts with the following command:java PingClient host portwhere host is the name of the computer the server is running on and port is the port number it is listening to. Note that you can run the client and server either on different machines or on the same machine.The client should send 10 pings to the server. Because UDP is an unreliable protocol, some of the packets sent to the server may be lost, or some of the packets sent from server to client may be lost. For this reason, the client cannot wait indefinitely for a reply to a ping message. You should have the client wait up to one second for a reply; if no reply is received, then the client should assume that the packet was lost during transmission across the network. You will need to research the API for DatagramSocket to find out how to set the timeout value on a datagram socket.When developing your code, you should run the ping server on your machine, and test your client by sending packets to localhost (or, 127.0.0.1). After you have fully debugged your code, you should see how your application communicates across the network with a ping server run by another member of the class.Message FormatThe ping messages in this lab are formatted in a simple way. Each message contains a sequence of characters terminated by a carriage return character (r) and a line feed character (n). The message contains the following string:PING sequence_number time CRLFwhere sequence_number starts at 0 and progresses to 9 for each successive ping message sent by the client, time is the time when the client sent the message, and CRLF represent the carriage return and line feed characters that terminate the line.

Hello! So I have been practising some coding, however, there seems to be an error in my code. I have been trying to figure out what is wrong, however, I just can't seem to find it. There is no syntax error but, there seems to be a problem with my input. I am currently using repl.it and I am making a calculator. I would input something like "multiply" however, the calculator would only square. I have tried changing the variables but it just keeps coming back to the first "if" statement. I would appreciate some help.
Answer:
You OR expressions are wrong.
Explanation:
Rather than writing:
if method == "Square" or "square":
You should write:
if method == "Square" or method == "square":
The expression should evaluate to something that is true or false.
In the above case, the expression is method == "Square" or method == "square" which can are actually two sub-expressions with an or in between them:
subexpr1 or subexpr2
each of the sub-expressions should evaluate to true or false.
method == "Square" is one of those sub-expressions.
That is how an expression is broken down by the compiler.
TIP: If you would add method = method.lower() right after the input, you could simplify all the if statements by removing the uppercase variants.

You are asked to write a program that prompts the user for the size of two integer arrays, user input for the size must not exceed 50, you must validate this. We will use these arrays to represent our sets. These arrays will be randomly populated in the range that is 1 through double the size of the array. So if the array is of size 20, you will randomly populate it with values in the range 1-40 inclusive.
Answer:
In Java:
import java.util.*;
public class MyClass{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Length of array 1: ");
int lent1 = input.nextInt();
while(lent1 <= 0 || lent1 > 50){
System.out.print("Length of array 1: ");
lent1 = input.nextInt();
}
int[] array1 = new int[lent1];
System.out.print("Length of array 2: ");
int lent2 = input.nextInt();
while(lent2 <= 0 || lent2 > 50){
System.out.print("Length of array 2: ");
lent2 = input.nextInt();
}
int[] array2 = new int[lent2];
for(int i =0;i<lent1;i++){
array1[i] = (int)(Math.random() * (lent1*2) + 1);
}
for(int i =0;i<lent2;i++){
array2[i] = (int)(Math.random() * (lent2*2) + 1);
}
System.out.print("Array 1: ");
for(int i =0;i<lent1;i++){
System.out.print(array1[i]+" ");
}
System.out.println("Array 2: ");
for(int i =0;i<lent2;i++){
System.out.print(array2[i]+" ");
}
}
}
Explanation:
This prompts the user for length of the first array
System.out.print("Length of array 1: ");
This declares and gets input for the length of the first array
int lent1 = input.nextInt();
This validates the length of first array
while(lent1 <= 0 || lent1 > 50){
System.out.print("Length of array 1: ");
lent1 = input.nextInt(); }
This declares the first array
int[] array1 = new int[lent1];
This prompts the user for length of the second array
System.out.print("Length of array 2: ");
This declares and gets input for the length of the second array
int lent2 = input.nextInt();
This validates the length of the second array
while(lent2 <= 0 || lent2 > 50){
System.out.print("Length of array 2: ");
lent2 = input.nextInt(); }
This declares the second array
int[] array2 = new int[lent2];
The following generates random integers between 1 and lent1*2 to array 1
for(int i =0;i<lent1;i++){
array1[i] = (int)(Math.random() * (lent1*2) + 1); }
The following generates random integers between 1 and lent2*2 to array 2
for(int i =0;i<lent2;i++){
array2[i] = (int)(Math.random() * (lent2*2) + 1); }
This prints the header Array 1
System.out.print("Array 1: ");
The following iteration prints the content of the first array
for(int i =0;i<lent1;i++){
System.out.print(array1[i]+" ");
}
This prints the header Array 2
System.out.println("Array 2: ");
The following iteration prints the content of the second array
for(int i =0;i<lent2;i++){
System.out.print(array2[i]+" ");
}

Therefore, memory is of the utmost importance and all programming code needs to be optimized to use the least amount of memory possible. What modifications could be made to reduce the memory requirements without changing the overall functionality of the code?
Answer:
Move Line 10 to after line 12
Explanation:
Required: Modify the program
From the procedure above, the procedure prints the sum at each loop. Unless it is really necessary, or it is needed to test the program, it is not a good practice.
To optimize the program, simply remove the line at displays the sum (i.e. line 10) and place it at the end of the loop.
So, the end of the procedure looks like:
Line 10: i <-- i 2
Line 11: }
Line 12: DISPLAY ( sum )
Line 13:
