Write a java program that finds the sum of all even numbers between 1 and 55.
Also what modification would you do to the program if you wanted the sum of all odd numbers between 1 and 55
Answer:
For sum of even Number :
public class even{
public static void main(String []args){
int sum = 0;
for(int i=1;i<=55;i++){
if(i%2==0){
sum = sum + i;
}
}
System.out.println(sum);
}
}
Modification for sum of odd:
change the condition of if statement:
i%2==1 instead of i%2==0
Explanation:
create the main function and declare the variable with zero.
Then, take a for loop for traversing the number from 1 from 55.
Inside the for loop, if statement check the condition for even number
A number is even if number divide by 2 and give zero reminder.
so, number%2==0 it is the condition for even number.
then add the even number until condition TRUE.
and finally print the result.
Modification for sum of odd number:
A number is odd, if number divide by 2 and give one reminder.
it means, number%2==1 it is the condition for odd number.
just change the if condition with above.
Make a ladtract class that has 2 fields, one for the tractor's length and one for the width. The class should have a method that returns the tract's area as well as an equals methos and a toString method.
Explanation:
Below is the java code for the ladtract class :-
public class ladtract
{
private double length; //length of tractor
private double width; //width of tractor
public double calculateArea(){
return length*width; //calculate and return the area of the tractor
}
public boolean equals(Object o) {
if (o == this) { //check if it's the same object
return true;
}
if(o.length==this.length && o.width==this.width){ //check if the length and width are same for both objects
return true;
}
return false;
}
public String toString(){
return "Area="+calculateArea(); //return the area of the tractor as a string
}
}
The destructor automatically executes when the class object goes out of ____.
A.
scope
B.
use
C.
phase
Answer:
scope
Explanation:
Destructor is a member function and it call automatically when the class object goes out of scope.
Out of scope means, the program exit, function end etc.
Destructor name must be same as class name and it has no return type.
syntax:
~class_name() { };
For example:
class xyz{
xyz(){
print(constructor);
}
~xyz(){
print(destructor);
}
}
int main(){
xyz num;
}//end program
when the object is create the constructor will called and when the program end destructor will call automatically.
Assume the following variables are defined: int age; double pay; char section; write a single c instatement that will read input into each of these variables. in c ++
Answer:
scanf("%d %lf %c", &age, &pay, §ion);
Explanation:
To read the value in c program, the instruction scanf is used.
To read the integer value, use the %d format specifier in the scanf and corresponding variable name age with ampersand operator.
To read the double value, use the %lf format specifier in the scanf and corresponding variable name pay with ampersand operator.
To read the character value, use the %c format specifier in the scanf and corresponding variable name section with ampersand operator.
The ____ operator is written as the exclamation point ( ! ).
a.
NOT
b.
assignment
c.
equality
d.
AND
Answer:
NOT
Explanation:
The operator '!' is called the NOT operator. it is used to invert the value of the Boolean.
if Boolean is TRUE then it make it FALSE.
if Boolean is FALSE then it make it TRUE.
For example:
!(6>0)
the expression gives the FALSE result. because the condition is TRUE 6>0
But the NOT operator make it FALSE.
Decision trees are onlyapplicable to problems under certainty.
True
False
Answer: False
Explanation:Decision tree is the tree like structured flowchart which is used for the evaluation of the possible outcomes or result of the particular problem. It usually has two or more branches as the the result node . Decision tree are applicable to many problems for solving it. So, decision trees is not only applicable on certainty problems but also on other problems as well. Therefore the given statement is false.
Write an if else statement that assigns 0 to the variable b and assigns 1 to the variable c if the variable a is less than 10. Otherwise, it should assign -99 to the variable b and assign 0 to the variable c.
Answer:
if(a < 10)
{ b = 0; c = 1;}
else
{ b = -99; c = 0;}
Explanation:
The if-else statement assigns values to variables b and c based on the condition whether a is less than 10. It assigns 0 to b and 1 to c if a < 10; otherwise, it assigns -99 to b and 0 to c.
This if-else structure is a fundamental concept in programming, allowing conditional execution of code based on whether a condition is true or false. For instance, if a equals 5, the values assigned will be b=0 and c=1, because 5 is less than 10. Conversely, if a equals 15, the assignments will be b=-99 and c=0.
if (a < 10) {Organizations are struggling to reduce and right-size their information foot-print, using data governance techniques like data cleansing and de-duplication. Why is this effort necessary? Briefly explain.
The effort is necessary in making sure that the data is meaningful, correct, and timely. Many analysts are increasingly focused on quality on a per-attribute basis instead of a per-report basis. This will avoid excess control of access and instead focus on meaning. A data-driven organization that includes a comprehensive data cleanup is able to make informed choices that maximize value on strategic investments.

Create a static method called fillArray, which takes an integer array as an input parameter, along with an integer initial value. It should then fill the array with values starting from the initial value, and counting up by 1s. For example, if the data array has length 5, and if the initialValue is 3, then after execution the array should hold this sequence: 3 4 5 6 7. public static void fillArray (int[] data, int initialValue) {
Answer:
public class print{
public static void fillArray(int[] arr, int initialValue){
int n = arr.length;
for(int i=0;i<n;i++){
arr[i] = initialValue++;
}
for(int i=0;i<n;i++){
System.out.print(arr[i]+" ");
}
}
public static void main(String []args){
int[] array = new int[5];
int initialValue =3;
fillArray(array,initialValue);
}
}
Explanation:
Create the function with two parameter first is array and second is integer.
Then, declare the variable and store the size of array.
Take the for and fill the array from the incremented value of initialValue by 1 at every run of loop.
After loop, print the element of the array.
Create the main function which is used for calling the function and also declare the array with size 5 and initialValue with 3. After that, call the function with this argument.
When you block statements, you must remember that any ____ you declare within a block is local to that block.
a.
decision
b.
expression
c.
method
d.
variable
When you block statements, you must remember that any method you declare within a block is local to that block.
What is Block statement?Each single statement in a Java program must be executed in the correct order. When all connected statements are enclosed in braces, we can sometimes produce a block statement that will be read as a single statement and allow us to use many statements to denote a single unit of work.
A compound statement that has been paired with a block statement is comparable.
When the class is loaded by JVM class loaders, the static blocks will only ever be executed once (Much like other static variables present at the class level).
Therefore, When you block statements, you must remember that any method you declare within a block is local to that block.

Where do you define parameter variables?
Answer:
In the function definition.
Explanation:
Function is the block of statement which is used to perform a special task.
when we define the function, we have call the function as well without calling function is not used.
syntax for calling:
name(argument_1,argument_1,...);
we put the argument in the calling to function.
syntax for defining:
type name(parameter_1,parameter_2,.....)
{
statement;
}
In the definition, we declare parameter for use the value of arguments pass in the calling.
Therefore, the answer is in the function definition.
Why maintaining a procedure guide for backup is important?
Once a try block is entered, the statements in a(n) ____ clause are guaranteed to be executed, whether or not an exception is thrown.
A) catch
B) String
C) close
D) finally
Answer:
D - Finally
Explanation:
Once the program has executed and exited the try-catch structure (when all error handling is completed), it always executes the finally clause. The finally clause is best utilized when you want code executed even if the try structure finds an exception.
All of the following are guidelines for effective small talk EXCEPT
a.discuss controversial topics.
b.avoid monologuing.
c.stress similarity rather than differences.
d.answer questions with sufficient elaboration.
Answer:
A - Discuss controversial topics
Explanation:
Small talk refers to polite, informal conversation that people engage in during social occasions. It is meant to be lighthearted, usually concerning unimportant topics. Therefore, the discussion of controversial topics goes against the purpose and characterization of effective small talk.
Which of the following is not a standard method called as partof the JSP life cycle?
? jspInit()
? jspService()
? _jspService()
? jspDestroy()
Final answer:
The method _jspService() is not a standard part of the JSP lifecycle; it's an implementation detail by JSP containers but not to be directly used by developers.
Explanation:
The question pertains to the standard methods in the JavaServer Pages (JSP) life cycle. In JSP, there are several lifecycle methods that the JSP container (like Tomcat or Jetty) calls to manage the JSP page. These methods include jspInit() for initialization, jspService() for processing requests, and jspDestroy() for cleanup when the JSP is about to be destroyed. However, the method _jspService() is not part of the JSP life cycle and is actually an implementation detail used by some JSP containers. This method is typically generated by the JSP container during JSP to servlet conversion and should not be called directly by developers.
Write a function called vowels that takes a string s and returns the number of vowels in the string: i.e. the number of letters that are
Answer:
int vowels(string s){
int count=0;
for(int i=0;s[i]!='\0';i++){
if(s[i]=='a' || s[i]=='e' ||s[i]=='i'||s[i]=='o'||
s[i]=='u'||s[i]=='A'||s[i]=='E'||s[i]=='I'||
s[i]=='O' || s[i]=='U'){
count++;
}
}
return count;
}
Explanation:
Create the function with return type int and declare the parameter as a string.
define the variable count for storing the output. Then, take a for loop for traversing each character of the string and if statement for checking the condition of the vowel.
vowel are 'a', 'e', 'i', 'o', 'u' in lower case. we must take care of the upper case as well.
vowel are 'A', 'E', 'I', 'O', 'U' in upper case.
if the condition is true to update the count by 1.
This process continues until the string not empty.
and finally, return the count.
In a java program, package declaration .................... import statements.
A) must precede
B) must succeed
C) may precede or succeed
D) none
Answer: (A)must precede
Explanation:In java, import statements are important part that allows to import the whole package or any specific class in the package.It is used to import the built-in as well as user defined packages into the java source files and because of this your class can also refer to outside class of other packages as well in a direct way.
In a java program, package declaration must precede import statements.
In a Java program, the package declaration, if present, must be the first line in the source file, excluding comments. This is because the package declaration defines the namespace in which the classes are stored, and it is crucial for the Java compiler to know the package before it processes any import statements or class definitions.
Import statements come after the package declaration and before any class or interface definitions. They allow the program to refer to classes that are declared in other packages, making the code more modular and easier to manage. The typical order in a Java source file is:
1. Package declaration
2. Import statements
3. Class or interface definitions
If a source file does not have a package declaration, it is placed in the default package. Proper ordering is essential for the correct compilation and organization of Java programs.
The correct answer is A) must precede.
Using the flowchart above, which decision statement will correctly check that hoursWorked is greater than or equal to the FULL_WEEK constant?
a.
hoursWorked >= FULL_WEEK
b.
hoursWorked > FULL_WEEK
c.
hoursWorked == FULL_WEEK
d.
hoursWorked != FULL_WEEK
Answer:
hoursWorked >= FULL_WEEK
Explanation:
The operator sign and meaning:
> means greater than
< means less than
= equal sign
! means NOT operator
== means equal equal sign
Option a: hoursWorked >= FULL_WEEK
It means hoursWorked is greater than or equal to FULL_WEEK.
Option b: hoursWorked > FULL_WEEK
It means hoursWorked is greater than to FULL_WEEK.
Option c: hoursWorked == FULL_WEEK
It means hoursWorked is equal equal to FULL_WEEK.
Option d: hoursWorked != FULL_WEEK
It means hoursWorked is not equal to FULL_WEEK.
Therefore, Option a is the correct option.
The correct decision statement to check if 'hoursWorked' is greater than or equal to 'FULL_WEEK' is 'a. hoursWorked >= FULL_WEEK'. This includes scenarios where 'hoursWorked' is exactly a full week or more.
Explanation:The decision statement that will correctly check whether hoursWorked is greater than or equal to the FULL_WEEK constant is:
a. hoursWorked >= FULL_WEEK
This statement checks if the variable hoursWorked is at least equal to the value of the FULL_WEEK constant. It covers both the scenario where hours worked are exactly equal to a full week and any amount of hours that is greater. In contrast:
b. is more than seven hours.c. only checks for exact equality with seven hours.d. checks for inequality, meaning not equal to seven hours.Where does execution resume after an exception has been thrown and caught?
Answer:
The execution resumes in the finally block if one exists or otherwise from the next statement following the try...catch block.
Explanation:
Once an exception has been thrown and caught in the code, the execution continues with the statements in the finally block if one exists. If there is no finally block defined then execution resumes from the next statement following the try... catch block. For example:
try{
//An exception is raised
}
catch (Exception e){
//Exception is handled
}
System.out.println("After try...catch");
In this code segment, the next statement to be executed after catch is the System.out.println();

Write a C++ program which contains a user-defined functionhaving name isSortedthat returnstrue if the array is sorted,and returns false if thearray is not sorted In main functionask the user to enter 10 integers and store them in array and thencall the function by passing this array. If array is sorted thendisplay message "Array is Sorted" otherwise displaymessage "Array is not Sorted"
Answer:
#include<iostream>
using namespace std;
//create the function
bool isSorted(int arrays[]){
int Array_size=10;//store the size
//check for condition if array is size 1 or zero
if(Array_size==1 || Array_size==0){
return true;
}
//traversing the array and check for sort
for(int i=1;i<Array_size;i++){
if(arrays[i-1]>arrays[i]){
return false;
}
}
return true;
}
//main function
int main(){
//initialization
int arrays[10];
cout<<"Enter the 10 numbers: "<<endl;
//for storing the value in array
for(int i=0;i<10;i++){
cin>>arrays[i];
}
//call the function and check is true or not and display message
if(isSorted(arrays)){
cout<<"Array is Sorted"<<endl;
}else{
cout<<"Array is not Sorted"<<endl;
}
return 0;
}
Explanation:
Include the library for using the input/output instruction.
create the function 'isSorted' with one parameter arrays and return type id bool. It means the function returns the true or false.
then, declare the variable and check the condition using the if-else statement. if the array size is zero or one, it means the array is sorted. So, the function returns true. otherwise, the program executes the next statement.
After that, take a for loop and traversing the array, an if-else statement is used for checking the previous element is greater than the next element, if condition true, the function returns the false.
after the loop checked all the element and the loop does not return false. It means the array is sorted and the function returns true.
create the main function and declare the array with size 10.
print the message on the screen and then store the element in the array.
we take a for loop and it runs 10 times. so, the user enters the number for every cycle of loop and store in the array.
after that, calling the function with an if-else statement, as we know the function returns the Boolean. So, if the function returns true then if statement executes and print message otherwise else statement executes and prints the appropriate message.

In super scalar, it is the processor with multiple pipeline instructions, which basically allowed various instruction to be process simultaneously in each cycle. It is basically the method of parallel computing which are used in various processor.
What are Loop Errors? Describe briefly. What aresymptoms of Loop Errors?
Answer:
The errors in the loop condition such that it is not giving desired results or it is not running accordingly.There are different types of loop errors which are as following:-
1.Infinite loop:-When the is not able to stop then the error is called infinite loop. for ex:-
int i=1;
while(i!=0)
{
cout<<"I am King"<<endl;
i++;
}
2.Off by one error:-This error mostly happens in loop for arrays as indexing of the array is from 0 to size-1 .So looping over the array up to the size is a off by one error.
3.Equality v/s assignment operator error:-In this error the condition in the loop is like this d=f which is wrong since = is assignment operator it assigns the value of f to d while d==f checks that the value of d and f are equal or not.
4.&& v/s || loop error:- In this error we use and operator (&&) instead of or operator (||) and vice versa.
symptoms of loop errors are not the desired output.

___ is an example of a calling statement.
A) float roi(int, double);
B) printf("%f", roi(3, amt));
C) float roi( int yrs, double rate);
D) float roi( int yrs, double rate)
Answer:
printf("%f", roi(3, amt));
Explanation:
To call the function, we have to put the function name without return type and if the function have parameter then we have to pass the parameter without data type as well.
Let discuss the options:
Option A: float roi(int, double);
it is not a calling, it is used to declare the function. In calling, return type of the function like float and data type of the parameter does not pass like int, double.
Option B: printf("%f", roi(3, amt));
print is used to display the result, inside the print it call the function. It is correct way to call the function.
Option C: float roi( int yrs, double rate);
it is not a calling, it is used to declare the function. In calling, return type of the function like float and data type of the parameter does not pass like int, double.
Option D: float roi( int yrs, double rate)
Same reason as option C.
Therefore, the option B is correct option.
