Answer:
public class average{
public static float getAverageOfFours(int[] arr){
int n = arr.length;
float sum = 0;
int count=0;
for(int i=0;i<n;i++){
if(arr[i]%4==0){
sum = sum+arr[i];
count++;
}
}
float avg = sum/count;
return avg;
}
public static void main(String []args){
int[] array = {10, 48, 16, 99, 84, 85};
float result = getAverageOfFours(array);
System.out.println("The average is "+result);
}
}
Explanation:
Create the function with one parameter and return type is float.
Declare the variable and store the size of array. Take a for loop for traversing in the array and and check the element is divisible by 4 or not by using if statement. If condition true take the sum and increment the count.
This process continue until the condition is true.
finally take the average and return it.
Create the main function for calling the function with pass the array as argument and also define the array.
After that print the result return by the function.

Write a C++ program that determines if a given string is a palindrome. A palindrome is a word or phrase that reads the same backward as forward. Blank, punctuation marks and capitalization do not count in determining palindromes. Here is some examples of palindromes:
Radar
Too hot to hoot
Madam!I'm adam
A C++ program to determine if a given string is a palindrome involves converting the string to the same case, removing non-alphanumeric characters, and then checking if the string is equal to its reverse. Below is a sample code that performs these steps:
#include
#include
#include
#include
bool isPalindrome(const std::string& str) {
std::string sanitized;
for (char ch : str) {
if (std::isalnum(ch))
sanitized += std::tolower(ch);
}
std::string reversed = sanitized;
std::reverse(reversed.begin(), reversed.end());
return sanitized == reversed;
}
int main() {
std::string input;
std::cout << "Enter a string to check if it is a palindrome: ";
std::getline(std::cin, input);
bool result = isPalindrome(input);
if(result) {
std::cout << "The string is a palindrome." << std::endl;
} else {
std::cout << "The string is not a palindrome." << std::endl;
}
return 0;
}
In the above program, the function isPalindrome takes a string and creates a sanitized copy by iterating over each character, checking if it is alphanumeric (ignoring spaces and punctuation), and converting it to lowercase. After constructing the sanitized string, it creates a reversed version and compares the two. The main function reads a string from the user, calls the isPalindrome function, and outputs the result.
Under Rule 504 ofRegulation D, a company can sell up to ______ of securitiesin
any 12-monthperiod.
a. $50,000
b. $100,000
c. $500,000
d. $1,000,000
Answer:
5,000,000 (5 million) of securities in any 12-month period.
Explanation:
Based on my extensive research on regulations. Rule 504 of Regulation D provides an exemption for having to register under the federal securities laws. This is usually for companies that are in business with products or services that are considered as securities or commodities. This Rule allows a company to sell up to 5,000,000 of securities in any 12-month period.

In a ____ queue, customers or jobs with higher priorities are pushed to the front of the queue.
A.
structured
B.
divided
C.
priority
Answer: In a priority queue, customers or jobs with higher priorities are pushed to the front of the queue.
Explanation:
A queue is an abstract data type which is an ordered set of elements. The elements are served in the order in which they join the queue. The first element which was put in the queue is processed first.
The operations performed on queue data type are dequeue and enqueue.
Dequeue refers to removal of the first element from the queue after it has been serviced.
Enqueue refers to the arrival of new element when the element is added at the end of the queue.
A priority queue is another implementation of a queue. All the elements in a priority queue are assigned a priority. The element with the higher priority is served before the element with a lower priority. In situations of elements having same priority, the element is served based on the order in which the element joined the queue.
In programming, a priority queue can be implemented using heaps or an unordered array. Unordered array is used based on the mandatory operations which are performed on the priority queue.
The mandatory operations supported by a priority queue are is_empty, insert_with_priority and pull_highest_priority_element. These operations are implemented as functions in programming.
The is_empty confirms if the queue is empty and has no elements.
The insert_with_priority puts the new element at the appropriate position in the queue based on its priority. If the priority of the element is similar to the priority of other element, the position of the new element is decided based on the order of joining the queue.
The pull_highest_priority_element pulls the element having the highest priority so that it can be served before other elements. The element having the highest priority is typically the first element in the priority queue.
In operating system, priority queue is implemented to carry out the jobs and/or tasks based on their priority.

What is the difference between an argument and a parameter variable?
Answer:
The value enter in the function calling is called argument. Argument passed to function.
The variable declare in the function to capture the pass value from the calling function is called parameters.
Explanation:
Argument is used in the calling function and parameter is used in the defining the function.
for example:
//create the function
int count(parameter_1, parameter_2,.....)
{
statement;
}
count(argument_1. argument_1,.....); //call the function
Write each of the following decimal values in binary. (Can please show me how you did arithmetic you to perform the conversion.)
47
14
81
102
241
Answer:
47 → 101111
14 → 1110
81 → 1010001
102 → 1100110
241 → 11110001
Explanation:
There are two ways to calculate binary equivalent of decimal values:
Divide the number by 2 as in the image, keep the reminder to right. then divide the divisor by 2 and keep the reminder to right and so on. Then read the reminders from top to bottom.Or you can start putting 1 at the nearest power of 2 that is smaller than decimal integer, then subtract that value from the decimal integer. Again put 1 at nearest power of 2 and so on.e.g.
For 102, we put 1 at 64. than 102[tex]-[/tex]64 = 38
then put 1 at 32, now 38 [tex]-[/tex] 32 = 6.
then put 1 at 4, now 6 [tex]-[/tex] 4 = 2.
then put 1 at 2, now 2[tex]-[/tex]2 = 0.
so put 0 at 1 and all other places except those where we put 1.

Write a program in which you input three numbers they canhave decimals so float values and the program gives you the minvalue out of the three. Please need asap thank you
Answer:
Following is the c++ code:-
#include <bits/stdc++.h>
using namespace std;
int main() {
float a,b,c;//declaring three float variables..
cout<<"enter values"<<endl;
cin>>a>>b>>c;//taking input..
float mi=min(a,b);//finding minimum in a and b..
mi=min(mi,c);// finding minimum from mi and c.
cout<<mi<<endl;//printing the answer.
return 0;
}
Explanation:
I have taken three float variables to hold the values.
then I am finding the minimum in a and b and storing it in mi.
Then finding minimum from mi and c so we will get our final minimum number.
What is the output after the following code executes?
int x=10; if ( ++x > 10 ) {
x = 13;
}
cout << x;
Answer:
13
Explanation:
First understand the meaning of ++x, it is a pre-increment operator.
it means, it increase the value first than assign to the variable.
For example:
x=10
then after executing ++x, the value of x is 11.
it increase the value and assign to x.
In the question:
The value of x is 10. After that, program moves to the if condition and check for condition (++x > 10) means (11 > 10) condition true.
then, 13 assign to x.
After that value of x is printed as 13.
Final answer:
The C++ code increments the variable x to 11 due to the pre-increment in the if statement, then changes x to 13 within the if block. Thus, the output of the code, when executed, is 13.
Explanation:
When the C++ code provided is executed, the statement int x=10; initializes the variable x with the value 10. The subsequent if statement checks if ++x > 10, where ++x is a pre-increment operation that increases x by 1 before the comparison. Since x is incremented to 11 before the comparison, the if block is executed, setting x to 13. The cout << x; statement then outputs the value of x, which at this point will be 13.
The characters << indicate that the value to the right is to be sent to the cout, which identifies the standard output stream. For cout to work, we need the inclusion of the iostream header file and the usage of the using namespace std; directive.
All of the followingshould be followed by entrepreneur for being effective
leader,EXCEPT:
a. Show respect foremployees
b. Show concern foremployees’ welfare
c. Try to do everythinghimself
d. Encourage and praiseothers
Answer:
C - Try to do everything himself
Explanation:
It is usually never advisable for an entrepreneur to attempt to do everything themselves. Delegation (assigning a task to a subordinate) is an important aspect of entrepreneurial leadership, this benefits the entreprenuer himself and allows his employees to feel a sense of confidence because they were trusted witht the task and it is a chance to show what they are capable of.

Find the second largest and second smallest element in a given array. You can hardcode/declare the array in your program.
Answer:
Program for Second largest in an array:-
#include <bits/stdc++.h>
using namespace std;
int main()
{
int f,s,n; //declaring 3 variables f for first largest s for second largest n is size.
cin>>n;//taking input size of the array.
if(n<2)//n should be greater than 2..
cout<<"n should be greater than 2"<<endl;
int a[n];// array of size n.
for(int i=0;i<n;i++)
{
cin>>a[i];
}
f = s = INT_MIN;//initialising f and s with minimum value possible.
for (int i =0; i <n;i ++)
{
if (a[i] > f)
{
s = f;
f = a[i];
}
else if (a[i] > s && a[i] != f)
s = a[i];
}
if (s == INT_MIN)
cout<<"No second largest exists"<<endl;
else
cout<<"Second largest element is :"<<s;
return 0;
}
Program for second smallest element is:-
#include <bits/stdc++.h>
using namespace std;
int main()
{
int f,s,n; //declaring 3 variables f for first smallest s for second smallest n is size.
cin>>n;//taking input size of the array.
if(n<2)//n should be greater than 2..
cout<<"n should be greater than 2"<<endl;
int a[n];// array of size n.
for(int i=0;i<n;i++)
{
cin>>a[i];
}
f = s = INT_MAX;//initializing f and s with maximum value possible.
for (int i =0; i <n;i ++)
{
if (a[i]<f)
{
s = f;
f = a[i];
}
else if (a[i] < s && a[i] != f)
s = a[i];
}
if (s == INT_MAX)
cout<<"No second smallest exists"<<endl;
else
cout<<s;//it is the second smallest element...
return 0;
}
Explanation:
For Second largest:-
1. Declare 3 variables f, s and n. where n is size the array f is first largest and s is second largest.
2. Initialize f and s with minimum value possible.
3. Iterate over the array a and do the following steps:-
1.If element at ith position is greater than f. Then update f and s.
s=f and f=a[i].
2.If the element is between s and f then update s as.
s=a[i].
4. Print s because it is the second largest in the array.
For Second smallest:-
1. Declare 3 variables f, s and n. where n is size the array f is first smallest and s is second smallest.
2. Initialize f and s with minimum value possible.
3. Iterate over the array a and do the following steps:-
1.If element at ith position is smaller than f. Then update f and s.
s=f and f=a[i].
2.If the element is between s and f then update s as.
s=a[i].
4. Print s because it is the second smallest in the array.

What is transaction? Differentiate between pre-emptiveand non pre-emptive transactions
Answer: Transaction is the process of processing information in a standalone system or distributed system. There are two basic types of systems which are preemptive and non preemptive transactions.
Explanation:
Transaction can be complete successfully or it can fail but it can never be partially completed. Computer processes which completes in its entirety or does not complete at all are termed as processes.
Preemptive processes are those where the cpu is allotted to a process for a definite time . The cpu can be given to another process if it has higher priority.
Whereas in non preemptive processes the cpu once allotted to a process cannot be assigned to another process until job is finished for the first process.

Explanation:
Given an array of integers an). The array is already NOT write C++ statements to fill the array eye write C++ statements that print to the screen how many values in the how many values are odd. In addition, the statements output to the scre the array that are even. s
Answer:
#include<iostream>
using namespace std;
int main () {
int n;
int odd=0,even=0;
cout<<"Enter the number of element store in the array: ";
cin>>n;
int arr[n];
for(int i=0;i<n;i++){
cin>>arr[i];
}
for(int i=0;i<n;i++){
if(arr[i]%2==1){
odd++;
}else{
even++;
}
}
cout<<"The number of odd values is: "<<odd<<endl;
cout<<"The number of even values is: "<<even<<endl;
}
Explanation:
Include the library iostream for input/output.
Create the main function and declare the variables.
Then, print the message on the screen and store the value enter by the user for the size of the array. After that, take a for loop and store the values in the array enter by the user.
then, take a for loop for traversing to the array and check the condition for odd and even by using if-else statement.
for odd: If odd values divided by 2 it gives 1 remainder.
for even: If even values divided by 2 it gives zero remainder.
if condition true, then update the counter.
finally, print the result.

Write a program which prompts user to enter a character, if the user presses „Z‟, the program asks user to enter a number. In this case the program implements 5-input majority voting logic which is explained as follows.The value of the number represented by the five leftmost bits of Register-B is tested. If the number of logic '1' bits (in the 5 leftmost bits) is greater than the number of logic '0' bits, the program should output: "The number of 1’s in the 5 left most bits is greater than the number of 0’s". If the number of logic '0' bits (in the 5 leftmost bits) is greater than the number of logic '1' bits, the program should output: "The number of 0’s in the 5 left most bits is greater than the number of 1’s"
What will the following C code print out?
int x = 7, y = 5;
if (x > 5)
if (y > 5)
printf(“x and y are > 5”);
else
printf(“x is <=5”);
a) “x and y are > 5”
b) “x is <=5”
c) nothing will be printed
Answer:
x is <=5
Explanation:
If-else is the statement that is used to execute the statement when the condition is true.
syntax:
if(condition){
statement;
}else{
statement;
}
if we do not provide the curly bracket, still the statement is valid.
in the question, x =7 and y=5
then, check the condition 7 > 5 condition true. it moves to the next if statement and check 5 > 5, condition false. Then it moves to the else part and executes the statement.
and print the output "x and y are > 5".
How do you return a value from a function?
Answer:
return instruction used to return a value from a function.
Explanation:
Function is a block of statement which perform the special task.
Syntax for define a function:
type name(parameter_1, parameter_2,...)
{
statement;
return variable;
}
In the syntax, type define the return type of the function. It can be int, float, double and also array as well. Function can return the array as well.
return is the instruction which is used to return the value or can use as a termination of function.
For return the value, we can use variable name which store the value or use direct value.
Write a program to print out the digits of a number in English. For example, if the number is 153, the output should be “One Five Three.” This program should allow users to input the number by using keyboard

int main() {
int n,a[100],c=0;
cout<<"Enter the integer"<<endl;
cin>>n;//taking input of n..
while(n>0)//storing the integer in the array in reverse order..
{
int digit=n%10;
a[c++]=digit;
n/=10;
}
int s=0,e=c-1;
while(s<=e)//reversing the array.
{
int temp=a[s];
a[s]=a[e];
a[e]=temp;
s++;
e--;
}
for(int i=0;i<c;i++)//printing the string according to the number..
{
cout<<value(a[i])<<" ";
}
cout<<endl;
return 0;
}
Output:-
Enter the integer
230
Two Three Zero
Explanation:
I have created a function which returns string according to the integer.So i have taken an array to store the digits of the number and reversing it so the number is stored as it is in the array.Then printing the numbers accordingly.
