Practice Question

What will be displayed after this

code segment is run?

count

0

REPEAT UNTIL (count = 3

count count + 1

DISPLAY

and"

DISPLAY count



"1 and 2 and 3"

"And 1 and 2 and 3"

"0 and 1 and 2"

"And 0 and 1 and 2"

Answer:

Follows are the code to the given question:

#include <stdio.h>//header file

int main()//main method

{

int count=0;//defining an integer variable

for(count=0;count<3;count++)//use for loop to count values

{

printf("%d\n",count);//print count values

}

return 0;

}

Output:

0

1

2

Explanation:

In this code, it declares the integer variable "count" which has a value of "0" and in the next step declares a loop, using the count variable to regulate count values, which is less than 3, and increases the count value, and prints its values. This variable is the count value.

The count variable holds a value of 0, and use a for loop that checks its value is less than 3, and print its value, that's why it will print the value that is 0,1, and 2.

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.

5.18 LAB: Output numbers in reverse Write a program that reads a list of integers, and outputs those integers in reverse. The input begins with an integer indicating the number of integers that follow. For coding simplicity, follow each output integer by a comma, including the last one. Ex: If the input is: 5 2 4 6 8 10 the output is: 10,8,6,4,2, To achieve the above, first read the integers into a vector. Then output the vector in reverse.

Write a SELECT statement that returns one row for each customer that has orders with these columns: The email_address from the Customers table

A count of the number of orders

The total amount for each order

(Hint: First, subtract the discount amount from the price. Then, multiply by the quantity.) Return only those rows where the customer has more than 1 order. Sort the result set in descending sequence by the total amount . Hint: You will join three tables together. Returns 3rows of data.

all questions before and after:

Write a SELECT statement that returns these columns:

The count of the number of orders in the Orders table

The sum of the tax_amount columns in the Orders table

Returns 1 row of data.

Write a SELECT statement that returns one row for each category that has products with these columns:

The category_name column from the Categories table

The count of the products in the Products table
