double nMiles, nKm;
Console.Write("Enter Value In Miles : ");
nMiles =Convert.ToDouble(Console.ReadLine());
nKm = (nMiles / 0.62137);
Console.WriteLine("Output:");
Console.WriteLine("Value In Miles :" + nMiles);
Console.WriteLine("Value In KM :" + nKm);
Console.Read();
}
}
}
Output:
Case A-
Enter Value In Miles : 10
Value In Miles : 10
Value In KM : 16.09347
Case B-
Enter Values In Miles : 3.25
Value In Miles : 3.25
Value In KM : 5.230378
Explanation:
Here we take a input value in "nMiles" variable and converted into a Km. that will stored in "nkm" variable . To convert miles into km we use calculative formula Km=(miles/0.62137). This formula convert the entered value into km and finally print the value of miles and km miles variable.
What is a foreign key and how does it provide referential integrity?
Answer:
By definition a foreign key of table A is a primary key of another table B, thereby establishing a link between them.
To provide referential integrity you can use these referential actions:
Cascade: If rows in table B are deleted, the matching foreign key columns in table A are deleted. Set Null: If rows in table B are deleted, the matching foreign key columns in table A are set to null. Set Default: If rows in table B are deleted, the matching foreign key columns in table A are set with the default value of the column. Restrict: A value in table B cannot be deleted or updated while as it is referred to by a foreign key in table A._________ is used in planning situations that involve much uncertainty, like that of IT in general and e-commerce in particular.
a. Key performance indicators (KPIs)
b. Scenario planning
c. Critical success factors (CSFs)
d. Balanced scorecard
Answer:b)Scenario planning
Explanation: Scenario planning is the strategy that is made for the generation of long term plan in an organization. It is also known as the scenario analysis . This is flexible technique in which helps the well structured and well managed future of organizations.
This tool considers the uncertainty and uncontrollable events that might happen in future and thus , these situation are analysed and acknowledged.
Other options are incorrect because Key performance indicator are for providing the key factor about the performance of organization, critical success factor are for achieving positive outcome and balanced scorecard is type of management plan framework.Thus the correct option is option(b).
Another ball dropped from a tower A ball is again dropped from a tower of height h with initial velocity zero. Write a program that asks the user to enter the height in meters of the tower and then calculates and prints the time the ball takes until it hits the ground, ignoring air resistance. Use your program to calculate the time for a ball dropped from a 100 m high tower
Answer:
// here is code in C++.
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// variable
double height;
// gravitational acceleration
double g=9.8;
cout<<"Please enter initial height:";
cin>>height;
// h=ut+(gt^2)/2
// here u, initial velocity is 0
// after simplification
double t=sqrt(2*height/g);
// print the time
cout<<"time taken by ball to hit the ground is:"<<t<<" seconds"<<endl;
return 0;
}
Explanation:
Read the initial height from user. Declare and initialize the earth gravitational acceleration "g=9.8" .Then the equation is h=ut+(gt^2)/2, here u is initial velocity which is 0.Then after simplify the equation t=sqrt(2*h/g). Put the values in the equation and find the time taken by ball to hit the ground.
Output:
Please enter initial height:100
time taken by ball to hit the ground is:4.51754 seconds
Final answer:
A Python program calculates the time a ball takes to reach the ground when dropped from a given height, illustrating basic principles of free fall in physics. For a 100 m tower, the time is approximately 4.51 seconds.
Explanation:
A student has asked to write a program that computes the time it takes for a ball to hit the ground when dropped from a tower of height h meters, assuming no air resistance. The formula to calculate the time t is derived from physics: t = √(2h/g), where g is the acceleration due to gravity, approximately 9.81 m/s². Using this formula, we candevelop a program in Python to ask the user for the height h and then compute and print the time t. To demonstrate, if the program is used with a tower height of 100 meters, the calculated time for the ball to reach the ground would be approximately 4.51 seconds.
Example Python Program
import math
def drop_time_from_height(height):
g = 9.81 # Gravity in m/s²
time = math.sqrt(2 * height / g)
return time
height = float(input("Enter the height of the tower in meters: "))
time = drop_time_from_height(height)
print("The ball takes", round(time, 2), "seconds to hit the ground.")
This program illustrates a straightforward approach to solving problems related to free fall and physics calculations, enhancing the understanding of concepts such as gravity and acceleration.

Give two separate print statements: one will print your name, the other will print your major. Ensure that both will print on the same line to the screen
Answer:
// here is code in java.
// import package
import java.util.*;
// class definition
class Main
{
// main method of the class
public static void main (String[] args) throws java.lang.Exception
{
try{
// print the name
System.out.print("my name is Sam. ");
// print the major
System.out.print("my major is CS.");
}catch(Exception ex){
return;}
}
}
Explanation:
In java, System.out.print() will print the statement but didn't go to the next line.If there is another System.out.print(), then it will also print into the same line.So here first the System.out.print() will print the name and second will print the major in the same line.
Output:
my name is Sam. my major is CS.

While the concept of ____ has well served scientists who share scientific text files and application developers who exchange code, the greater use has been in downloading artistic files, such as music and video files.
VPNs
LANs
point-to-point file protocol
peer-to-peer (P2P) file sharing
Answer: peer-to-peer (P2P) file sharing
Explanation: Peer-to-peer file sharing is the technique in which networking technology is used for the sharing and distribution of the files digitally. The sharing of the files are in the form of movies, games music etc.
Peer are considered as the nodes which are the end-user so, the end-user to end-user file transfer is done through this technology.
Other options are incorrect because VPN(virtual private network) is the connection between network and client over less secure network,LAN (Local area network) is the network that can be established for single infrastructure to connect and point to point protocol is protocol for the routers for communication.Thus the correct option is P2P file sharing.

Why is String final in Java?
Answer:
string objects are cached in string pool.
Explanation:
Strings in Java are immutable or final because the string objects are cached in String Pool.As we know multiple clients share the string literals so there exists a risk of one client's action affecting all other clients.
For ex:-The value of string is "Roast" and client changed it to "ROAST" so all other clients will see ROAST instead of Roast.

Write a function called reverse() with this prototype:
void reverse(char dest[], char source[], int size);
Your function should copy all the elementsin the array source into the array dest, except in reverse order. The number of elements in the source array is give in the parameter size. Use a for loop to do the copying. Assume that dest is large enough to hold all of the elements. Please be thorough with commenting.
Answer:
void reverse(char dest[], char source[], int size)
{
for(int i=0;i<size;i++)//using for loop.
{
dest[i]=source[i];//assigning each element of source array to dest array.
}
int s=0,e=size-1;//initializing two elements s with 0 and e with size -1.
while(s<e){
char t=des[s]; //SWAPPING
dest[s]=dest[e]; //SWAPPING
dest[e]=t; //SWAPPING
s++;
e--;
}
}
Explanation:
I have used while loop to reverse the array.I have initialize two integer variables s and e with 0 and size-1.Looping until s becomes greater than e.
It will work as follows:
first s=0 and e=0.
dest[0] will be swapped with dest[size-1]
then s=1 and e=size-2.
then des[1] will be swapped with dest[size-2]
and it will keep on going till s is less than e.
Does Kennesaw State University have any computing ethical policy for computer usage? If so - what is it?
Answer:
The answer to the questions: Does Kennesaw State University have any computing ethical policy for computer usage? If so - what is it? Would be as follows:

List at least three benefits of automated testing?
Answer:
Always available to run: You can run the tests 24/7, when you are at work, when you leave the office or if you working remote, you can run the test. They can be run virtually unattended, leaving the results to be monitored towards the end of the process.
Fewer human resources: You can reduce the people advocated on testing, you would need a QA automation to write your scripts to automate your tests, instead of people doing manual tests. In addition, once automated, the test library execution is faster and runs longer than manual testing.
Reusability and reliability: The scripts are reusable, a script could be used hundreds of times before need changes. It allows you to test exactly the same, without forgetting any steps this is why is more reliable and way quicker than manual test where people may cause.
What is TCP/IP's Transport layer's primary duty?
Answer:
The TCP/IP is the transmission control protocol and internet protocol and in the TCP/IP model the transport layer is the second layer.

"What does the list look like after this code executes?
colors = "red,orange,yellow,green,blue"
s = colors.split(",")
["red", "orange", ""yellow", "green", "blue"]
["red orange yellow green blue"]
[red,orange,yellow,green,blue]
red
Answer:
The list created by the split method in Python 3 will be ["red", "orange", ""yellow", "green", "blue"]
Explanation:
In Python 3, the split method takes the input string, in this case is colors = "red,orange,yellow,green,blue", and split it into a list and you can indicate the separator that the method will use.
The general syntax for this method is:
string.split(separator,max)
separator indicates the character that will be used as a delimiter of each list member and the max parameter indicates the maximum number of separations to make.
Since each color in your string is separated by the character "," the code will make a list in which every color is a separated string.
Write a C program that prints the numbers from 1 to 100, but substitutes the word "fizz" if the number is evenly divisble by 3, and "buzz" if the number is divisible by 5, and if divisible by both prints "fizz buzz" like this: 13 1 14 2 fizz 4 buzz fizz 7 fizz buzz 16 17 fizz 8 fizz buzz 19 buzz ... 11 fizz and so on
Answer:
// here is code in C.
#include <stdio.h>
int main(void) {
int num;
// loop run 100 times
for(num=1;num<=100;num++)
{
//check divisibility by 3 and 5
if(num%15==0)
{
printf("fizz buzz ");
}
// check divisibility by 5 only
else if(num%5==0)
{
printf("buzz ");
}
// check divisibility by 3 only
else if(num%3==0)
{
printf("fizz ");
}
else{
printf("%d ",num);
}
}
return 0;
}
Explanation:
Run a for loop from 1 to 100. Check the divisibility of number by 15, if it is divisible print "fizz buzz", if it is not then Check the divisibility by 5 only.if it returns true then print "buzz". if not then check for 3 only,if returns true, print "fizz". else print the number only.
Output:
1 2 fizz 4 buzz fizz ........buzz fizz 97 98 fizz buzz

In a typical configuration the total RAM capacity is less than total ROM capacity.
True
False
False
Explanation:The difference between RAM and RAM is as follows
(1) RAM (random access memory) is meant for temporary storage whereas ROM (read-only memory) is meant for permanent storage.
(2) RAM chip is volatile, means once the power is turned off, it loses the previously holding information, where as ROM is non-volatile it doesn't losses any information even though power is turned off.
(3) RAM chip is used in the normal operations of the computer, whereas the ROM chip is used mainly for the startup process of computer.
(4) Generally, A RAM can store several gigabytes (GB) of data that is up to 16 GB whereas a ROM chip can typically store that much data. It only stores several megabytes (MB) of data that is up to 4 MB.
hence, the given statement about RAM is false.
Which of the following statements is/are true? (Points : 5) A. A default constructor is automatically created for you if you do not define one.
B. A static method of a class can access non-static members of the class directly.
C. An important consideration when designing a class is identifying the audience, or users, of the class.
None of the above
Only A and C
Answer: Only A and C
Explanation: Default constructor is a constructor that has parameters with the values that are default or has no arguments/parameter present. Default constructor is not declared in the class rather it gets generated by itself when not defined.
Class is defined with data members, functions, objects etc are considered as per the requirement given by the user .It is the user defined concept.
Statement (B) is incorrect because static method is used for accessing the static members of the particular class and manipulate the value of it.
Thus, only statement (A) and (C) are correct.
