Answer:
loop
Explanation:
Loop is the one which is used to execute the specific statement again and again until the condition is true.
In the programming, there are 3 basic loop used.
1. for loop
Syntax:
for(initialization, condition, increment/decrement)
{
statement;
}
the above statement execute until the condition in the for loop true when it goes to false, the loop will terminate.
2. while loop
Syntax:
initialization;
while(condition)
{
statement;
increment/decrement;
}
it is work same as for loop and the increment/decrement can be write after or before the statement.
3. do while
syntax:
initialization;
do
{
statement;
increment/decrement;
}while(condition);
here, the statement execute first then, it check the condition is true or not.
so, if the condition is false it execute the statement one time. this is different with other loops.
Final answer:
A loop is a structure that allows repeated execution of a block of statements in programming. It is controlled by a condition that, when false, will terminate the loop to prevent an infinite loop.
Explanation:
The correct answer to the question is b. loop. A loop is frequently used in programming to allow the repeated execution of a block of statements until a specified condition is met. Loops are a form of conditional control flow that can drastically alter the execution path of a program.
For instance, a while-loop will continue to execute so long as its condition remains True. If the condition evaluates to False, the loop terminates and control is passed to the statements that follow. During each iteration within the loop, it is essential to modify some variables, such as the iteration variable, to ensure the loop does not continue indefinitely, potentially leading to an infinite loop.
There is no reason to put comments in our code since we knew what we were doing when we wrote it. TRUE
Answer:
False: There are reasons to put comments in our code. We should have the habit of that.
Explanation:
sometimes when we start to debug our program due to some error in execution, we don't recognize properly which code we have written for what purpose.if we distribute the code to others as a team, others get the intention of our code more clearly due to comments.The code can be reused taking it's sections to form an other program, where the comments has a vital role.What are the first and the last physical memory addressesaccessible using
the following segment values?
a) 1000
b) 0FFF
c) 0001
d) E000
e) 1002
Answer
For First physical memory address,we add 00000 in segment values.
For Last physical memory address,we add 0FFFF in segment values.
NOTE-For addition of hexadecimal numbers ,you first have to convert it into binary then add them,after this convert back it in hexadecimal.
a)1000
For First physical memory address, we add 00000 in segment value
We add 0 at the least significant bit while calculating.
10000 +00000 = 10000 (from note)
For Last physical memory address,We add 0 at the least significant bit while calculating.
we add 0FFFF in segment value
10000 +0FFFF =1FFFF (from note)

For First physical memory address,we add 00000 in segment value
We add 0 at the least significant bit while calculating.
0FFF0 +00000=0FFF0 (from note)
For Last physical memory address,We add 0 at the least significant bit while calculating.
we add 0FFFF in segment value
0FFF0 +0FFFF =1FFEF (from note)
c)0001
For First physical memory address,we add 00000 in segment value
We add 0 at the least significant bit while calculating.
00010 +00000=00010 (from note)
For Last physical memory address,We add 0 at the least significant bit while calculating.
we add 0FFFF in segment value
00010 +0FFFF =1000F (from note)
d) E000
For First physical memory address,we add 00000 in segment value
We add 0 at the least significant bit while calculating.
E0000 +00000=E0000 (from note)
For Last physical memory address,We add 0 at the least significant bit while calculating.
we add 0FFFF in segment value
E0000 +0FFFF =EFFFF (from note)
e) 1002
For First physical memory address,we add 00000 in segment value
We add 0 at the least significant bit while calculating.
10020 +00000=10020 (from note)
For Last physical memory address,We add 0 at the least significant bit while calculating.
we add 0FFFF in segment value
10020 +0FFFF =2001F (from note)
T F A stub is a dummy function that is called instead of the actual function it
represents.
Answer: True, stub function is a dummy function that is called instead of actual function.
Explanation: A stub function is a function which has the name , parameters of a function but is used for production of the dummy output which is in correct form. It is put in a function so that it becomes convenient when a function is called it can be tested before it is completely written which saves the execution of wrong code.Therefore the given statement is true.

This statement is false.
True / False
. Fixed length instruction sets are generally slower to execute than variable-length instruction sets.
Answer: False
Explanation:
Fixed length instructions are faster than variable length instruction because the fixed length instruction uses one clock cycle for their instruction whereas variable instruction takes more than one clock cycle. As RISC uses fixed length instruction and its CPI(cycles per instruction) is less compared to CISC which uses variable length instructions.
So fixed length instruction sets are faster than variable length instruction.
Write a C++ code that will read a line of text and echo the line with all uppercase letters deleted. Assume the maximum length of the text is 80 characters. Example input/output is shown below.
Input:
Today is a great day!
Output:
oday is a great day!
Answer:
#include<bits/stdc++.h>
using namespace std;
int main()
{
string st;
getline(cin,st);
int i=0;
while(i<st.length())
{
if(isupper(st[i]))
{
st.erase(st.begin()+i);
continue;
}
i++;
}
cout<<st<<endl;
return 0;
}
Explanation:
I have included the file bits/stdc++.h which include almost most of the header files necessary.
For taking the input as a string line getline is used.
For checking the upper case isupper() function is used. cctype header file contains this function.
For deleting the character erase function is used.
public class Myfile { public static void main (String[] args) { String biz = args[1]; String baz = args[2]; String rip = args[3]; System.out.println("Arg is " + rip); } } Select how you would start the program to cause it to print: Arg is 2 A. java Myfile 222 B. java Myfile 1 2 2 3 4 C. java Myfile 1 3 2 2 D. java Myfile 0 1 2 3
Answer:
java MyFile 1 3 2 2
Explanation:
Option is is the correct answer, whatever we pass as commadD line arguments can be accessed using String array args by passing index
Array indexes starts with zero, in our case when we say
java MyFile 1 3 2 2
its going to be store like args[0] = 1, args[1] = 3, args[2] = 2, args[3] = 2
now we are saying System.out.println("Arg is " + rip);
it means its going to print Args is with value of rip i.e. 2 (rip=args[3])
Write a program to display a message telling the educational level of a student based on their number of years of school. The user should enter a number indicating the number of years of school, and the program should then print the corresponding message given below. Be sure to use named constants rather than any numbers other than 0 in this program.
Answer:
#include <iostream>
using namespace std;
int main()
{
int years;
cout<<"enter the number of years of school: ";
cin>>years;
cout<<"The educational level is: "<<years<<endl;
}
Explanation:
First include the library iostream in c++ program for input/output.
then create the main function and declare the variable.
after that, display the message by using cout instruction for asking the user to enter the value.
then, cin instruction store the value in the declare variable.
finally, display the message with corresponding value.
Final answer:
The provided Python program prompts for a score between 0.0 and 1.0, validates the input, and then outputs the corresponding grade or an error message if the input is not a number or out of range.
Explanation:
Here is a Python program that prompts for a score between 0.0 and 1.0, checks whether the score is in the valid range, and then prints the corresponding grade based on the score provided:
# Define named constants for grade thresholds
GRADE_A = 0.9
GRADE_B = 0.8
GRADE_C = 0.7
GRADE_D = 0.6
try:
score = float(input('Enter a score between 0.0 and 1.0: '))
if score < 0.0 or score > 1.0:
print('Error: Score is out of range.')
elif score >= GRADE_A:
print('A')
elif score >= GRADE_B:
print('B')
elif score >= GRADE_C:
print('C')
elif score >= GRADE_D:
print('D')
else:
print('F')
except ValueError:
print('Error: Please enter a numeric input.')
The program uses try and except blocks to handle non-numeric inputs gracefully, outputting an error message in such cases. Depending on the score entered by the user, the appropriate grade is printed using comparison operations against the named constants defining grade thresholds.

True of False - use T or FThe Exception class can be extended.
Answer:
T
Explanation:
java.lang.Exception class can be extended. That is you can define subclasses for the Exception class. In fact all out of the box Exception classes in Java like java.io.IOException, java.lang.NumberFormatException, javax.jms.JMSException extend the base class java.lang.Exception or its subclasses. The subclassing is valid because Exception class is not declared as a final class.
Answer:
true
Explanation:
Is the Internet a LAN or a WAN?
give the answer at least five line for one question
Answer:
Internet is a WAN (wide are network)
Explanation:
Great question, it is always good to ask away and get rid of any doubts that you may be having.
The Internet is a worldwide interconnected network with computers acting as nodes around the world. Communicating and sharing information between one another. LAN and WAN are connection types for the Internet.
LAN is a Local Area Network, which interconnects local computer nodes physically using Ethernet cables. Which are then connected to the internet itself.
WAN are wide area networks, which are usually interconnected through public communication services such as telephone cable.
Therefore the Internet is a WAN (wide are network)

What is the cause of thrashing?How does the systemdetect thrashing.Once it detects thrashing what can the system doto eliminate this problem
Answer:
Thrashing :- It is a situation when the system most of it's time is handling page faults, but the actual work done by CPU is very less.
Thrashing is caused by when a process is allocated too few number of frames, then there will be continuous page faults.The actual Utilization of CPU is very less.
Thrashing detection can be done by the system by determining the CPU Utilization as compared to degree of multi programming if it comes out to be less then there is thrashing.
Thrashing can be eliminated by decreasing the Degree of multi programming.
A while loop's body can contain multiple statements, as long as they are enclosed in braces
True False
Answer:
True
Explanation:
while loop is used to execute the statement again and again until the condition is true. if condition False program terminate the while loop and start execute the statement outside the loop.
syntax:
initialize;
while(condition)
{
statement 1;
statement 2;
to
statement n;
}
we can write multiple statement within the braces. their is no limit to write the statement within the body of the while loop.
while terminate only when condition false
