program for bit stuffing...?
Answer: Program for bit stuffing in C
#include<stdio.h>
int main()
{
int i=0,count=0;
char data[50];
printf("Enter the Bits: ");
scanf("%s",data); //entering the bits ie. 0,1
printf("Data Bits Before Bit Stuffing:%s",databits);
printf("\nData Bits After Bit stuffing :");
for(i=0; i<strlen(data); i++)
{
if(data[i]=='1')
count++;
else
count=0;
printf("%c",data[i]);
if(count==4)
{
printf("0");
count=0;
}
}
return 0;
}
Explanation:
bit stuffing is the insertion of non-information bits during transmission of frames between sender and receiver. In the above program we are stuffing 0 bit after 4 consecutive 1's. So to count the number of 1's we have used a count variable. We have used a char array to store the data bits . We use a for loop to iterate through the data bits to stuff a 0 after 4 consecutive 1's.
Which of the following statements is false? a. Racks and bins are examples of storage equipment. b. Automation refers to equipment that complements, rather than replaces, human contact. c. Forklifts can be dangerous. d. In a part-to-picker system, the pick location is brought to the picker.
Answer:
b. Automation refers to equipment that complements, rather than replaces, human contact.
In these kinds of systems, a mechanical device—typically—brings the pick location to the picker. The device's transit time is crucial in part-to-picker systems. Since the proper pick position is automatically offered, the picker's search time is greatly decreased. Thus option B is correct.
What best define about In a part-to-picker system?Systems for picking orders from warehouses are created to improve picking operations' effectiveness, speed, and accuracy. One or more of these systems can be used by businesses to improve order fulfilment processes in their distribution centres.
In this approach, warehouses set up a space for material handling, where merchandise is frequently moved using forklifts. Additionally, the system has a picking section where order pickers acquire goods to complete customer orders.
Therefore, Automation refers to equipment that complements, rather than replaces, human contact.

Many software application have security measurement against malicious attacks, so the future of security testing improves the software flaws.
Which algorithm makes the most efficient use ofmemory?
Answer:
Best-fit Algorithm
Explanation:
Best-fit: Allocating the smallest memory location that is greater than or equal to the size of process.
Example
Let these are the memory locations-210kb,310kb,260kb,610kb
and size of processes-160kb,450kb,250kb,300kb
For the first-fit,
We allocate 160 kb to the 210kb memory location
Then, we allocate 450 kb to the 610kb because others don't have the size.
Then,we allocate 250kb to the 310 kb.
300 kb will stop,as no memory locations can execute.
For the Best-fit,
We allocate 160 kb to the 210kb memory location
Then,we allocate 450kb to the 610kb.
Then,we allocate 250kb to the 260kb not 310kb according to best-fit.
Then we allocate 300kb to the 310kb.
For the worst fit,
We allocate 160 kb to the 610kb memory location according to the worst-fit algorithm.
Then,we can't allocate 450kb to any memory location.
Then,we allocate 250kb to the 310kb .
We can' allocate 300kb in 260kb memory location.
As we can see from this example that in First-fit algorithm 300kb process will stop as no memory location is there.
In worst-fit algorithm ,We can't allocate 450kb,300kb to any memory locations.
In Best-fit algorithm,we can allocate the process to each location,so this algorithm is using memory in a efficient way.
Two input capture events occur at counts 0x1037 and 0xFF20 of the free-running counter. How many counts, in decimal have transpired between these two events?
A. 25,891
B. 57, 421
C. 61,161
D. 64, 551
Answer:
The correct answer is C.
Explanation:
You have to do 0xFF20 - 0x1037 but first, you need to convert the counts from hexadecimal base system to decimal base system using this formula:
[tex]N = x_{1} * 16^{0} + x_{2} * 16^{1} + x_{3} * 16^{2} + x_{4} * 16^{3} + ... + x_n 16^{n-1}[/tex], where position of the x₀ is the rightmost digit of the number.
Note:
A = 10.B = 11.C = 12.D = 13.E = 14.F = 15.0xFF20 = 15*16³+15*16²+2*16¹ = 65312
0x1037 = 1*16³+3*16¹+7*16⁰ = 4151
Result: 65312 - 4151 = 61161

Write a C++ programme that asks the user to enter his age in days.Calculate then his age in:
Years – Months –Days
1 year = 365 days
1 year = 12 months
1 month = 30 days
C++ program that asks the user to enter his age in days
#include <iostream>
using namespace std;
void Findage() //Defining function
{
int a=0,d=0, m=0, y=0, r=0;
cout<<"Enter Age in Days= "; //Taking input
cin>>a;
if(a>365) //If age is greater than 365
{
y=(a)/365;
r=a%365;
if(r>30)
{
m=r/30;
d=r%30;
}
else
{
d=r%30;
}
}
else //if the age is less than 365
{
if(a>30)
{
m=(a)/30;
d=a%30;
}
else
{
d=a;
}
}if(a==365) //Printing output
{ cout<<"Your Age in Calender"<<endl;
cout<<"Year = 1"<<endl;
}
else
{
cout<<"Your Age in Calender"<<endl;
cout<<"Years= "<<y<<" Month="<<m<<" Days= "<<d<<endl;
}
}
int main()
{
Findage(); //Calling function
return 0;
}
Output
Enter Age in Days= 3697
Your Age in Calender
Years= 10 Month=1 Days= 17
A C++ program can be written to calculate a user's age in years, months, and days by dividing the total number of days provided by the user by 365 to find years and then dividing the remainder by 30 to calculate months, with the final remainder indicating the days.
A C++ program that calculates a user's age in years, months, and days from the age in days can be composed using simple arithmetic operations. Given that 1 year is 365 days, 1 year is 12 months, and 1 month is 30 days, the following process can be followed:
Ask the user for their age in days.
Use the remainder of the previous division to calculate the number of months by dividing by 30.
The remainder of the last division will give the number of days.
The resulting calculations will give the user's age in years, months, and days.

Cash cows are always in
a. Introductory industry
b. Growing industry
c. Mature industry
d. Declining industry
Answer:
The correct answer is C. Cash cows are always in mature industry.
Explanation:
A cash cow is a company, business area or product that generates a large free cash flow over time. Cash flow depends on the profitability of the company or product, that is, revenues are greater than costs, but also because the surplus is not tied up in the business in the form of working capital.
The cash flow in a company can be used to pay off debt but also as a dividend to owners. An individual product that constitutes a cash cow can help to finance other activities in the company or group.

Write a program to define three variables to hold three test scores. The program should ask the user to enter three test scores and then assign the values entered to the variables. The program should display the average of the test scores and the letter grade that is assigned for the test score average. Use the grading scheme in the following table. 90 or greater 80-89 70-79 60-69 Below 60
Answer:
It's always good to use if else with boolean expressions in such cases.
Explanation:
I have written a program where I have used c# as programming language.
I used if else block with boolean expressions to enforce conditions to print the grades according to the average of test scores. I have used Logical And(&&) operator in boolean expressions so that all the conditions in if and if else must be true
Here is the program:
using System;
public class Test
{
public static void Main()
{
int testScore1, testScore2, testScore3;
Console.WriteLine("enter first testScore");
testScore1 = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("enter second testScore");
testScore2 = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("enter third testScore");
testScore3 = Convert.ToInt32(Console.ReadLine());
float avg = (testScore1 + testScore2 + testScore3) / 3;
if(avg>=90)
{
Console.WriteLine("You got grade A");
}
else if(avg >=80 && avg <=89)
{
Console.WriteLine("You got grade B");
}
else if (avg >= 70 && avg <= 79)
{
Console.WriteLine("You got grade c");
}
else if (avg >= 60 && avg <= 69)
{
Console.WriteLine("You got grade D");
}
else if(avg< 60)
{
Console.WriteLine("You got grade E");
}
else
{
Console.WriteLine("Sorry, You failed");
}
Console.ReadLine();
}
}
Explanation of program:
I created three variables named, testScore1, testScore2, testScore3 of datatype int. I prompted the user to enter three test score values. Each value is read using Console.ReadLine() . As the value entered is of type integer, I converted the console read value into int using Convert method.
In the next step, I calculated average using the formula.
Now, Based on the average, I can calculate the grade according to the given grading scheme.
Something within a while loop must eventually cause the condition to become false, or a(n) __________ results.
1. null value
2. infinite loop
3. unexpected exit
4. compiler error
5. None of these
Answer: Infinite loop
Explanation:
A while loop terminates when the condition within the loop becomes false else the it will continue to loop for ever and thereby lead to memory overflow.
example : while(i<10)
{ print("hello");
}
here if value of i <10 then it will print hello, but if there is no condition it will lead to an infinite loop. example : while();

yes
Explanation:
isn't really noted but if the sequence is in the given order the ("3at4") could be expressed in a ('0' to '9' )format
Write an application that can hold five integers in an array. Display the integers from first to last, and then display the integers from last to first.
Answer:
Create an integer array which holds five integers
Explanation:
I have written a simple program using c# as a programming language.
Here's the program:
using System;
public class Test
{
public static void Main()
{
int[] numbers = new int[5];
Console.WriteLine("enter 5 numbers");
for (int i=0; i<=4; i++)
{
numbers[i]= Convert.ToInt32(Console.ReadLine());
}
foreach(int k in numbers)
{
Console.WriteLine(k+ "\n");
}
Console.WriteLine("----------------------------");
Console.WriteLine("In reverse");
for(int j=4; j>=0; j--)
{
Console.WriteLine(numbers[j] + "\n");
}
Console.ReadLine();
}
}
Explanation of Program:
I have created an array named "numbers" and assigned 5 as it's fixed size.
I prompted the user to enter numbers up to 5. I read those input numbers using Console.ReadLine() and converted to integers as return type of Console.ReadLine() is string. I have stored all inputs from user into an array while reading as below:
numbers[i]= Convert.ToInt32(Console.ReadLine());
Next step is to print them. We can do it easily using foreach loop where it pulls out elements from an array until it reaches end of an array and print them on console.
If I need to print them from first to last, the condition is,
for (int i=0; i<=4; i++)
as it needs to start from first element
If I need to print them from last to first, the condition is,
or(int j=4; j>=0; j--)
as it needs to start from last element
The application that can hold five integers in an array and display the integer from first to last and last to first is as follows;
integers = [15, 17, 8, 10, 6]
print(integers)
x = integers[::-1]
print(x)
Code explanation:The code is written in python.
The first line of code, we declared a variable named integers. This integers variables holds the 5 integers.The second line of code, we print the the integers from first to last.The next line of code, we reversed the array from last to first and stores it in the variable x. Then, we print the x variable to get the code from last to first.learn more on array here:https://brainly.com/question/19587167
Write an if statement that prints the message “Application accepted” if the variable workExperience is greater than or equal to 2 or the variable hasCollegeDegree is true.
