The valid IPv4 addresses are A. 1.1.1.1, C. 54.45.43.54, and D. 255.255.255.0
Valid IPv4 addresses are 32 bits in size and normally contain three periods and four octets like 1.1.1.1, and the value can be any number from zero to 255.
IPv4 means Internet Protocol version 4. It is a set of address that identifies a network interface on a computer.
Thus, the only invalid address according to IPv4 standards is B. 345.0.24.6, with others regarded as valid IPv4 addresses.

b) Within that file only
c) global
Answer:
The correct answer for the given question is option(a) i.e Local - within that function.
Explanation:
The variable which is declared inside any function are called as local variable The scope and lifetime of local variable is inside that block or function only.
They cannot access outside the function.
Following are the example of local variable
#include <stdio.h> // header file
void fun(); // function prototype
int main()// main function
{
fun(); //calling function
print("%d",t); // it gives error because t is local variable cannot access in main function
return 0;
}
void fun()
{
int t=9;// local variable
printf("t is local variable which value is:");
printf("%d",t);
}
As we seen that t cannot access outside the function .So correct answer is option(a)
The scope of a variable declared inside of a function is local - within that function. This prevents naming conflicts and ensures control over where a variable can be changed.
The scope of a variable declared inside of a function is typically local to that function. This means that it can only be accessed and manipulated within the function it is declared. It is not visible or accessible from outside of the function or elsewhere in the program file, hence options b) and c) are incorrect. This principle is fundamental in programming languages such as JavaScript, C++, Python, etc., and it is designed this way to prevent naming conflicts and provide control over where a variable can be changed.

Answer:
Human visual behavior often includes searching, scanning, and monitoring.
While it should be possible to moderate the performance of these tasks based on the dimensions used in the table, it is often useful to analyze these situations using Signal Detection Theory (SDT).
Three suggestions for my favourite search engine that includes search are:
1. ensure that search results are graded according to the following categories using different colours:
These can help the users identify more easily the results to spend more time on. This categorisation can be done using colours. This is because of the way the eye functions. Unlike a camera snapshot, for example, the eye does not capture everything in a scene equally, but selectively picks out salient objects and features from the current context, and focuses on them so they can be processed in more detail.
2. Another suggestion is that attention needs to be paid to where people look most of the time. It is not out of place for people to instinctively avoid search results that have dollar signs or currency signs especially when they are not searching for a commercial item.
3. Lastly in displaying results that have images, it best to use sharp images. The theory suggests with respect to contrast, clarity and brightness that sharper and more distinct objects appear to be nearer, and duller objects appear to be farther away. To elicit the interest of the reader, targeted results or information from search engines must make use of the factors of contrast, clarity and brightness.

Answer:
#include<iostream>
using namespace std;
//main function
int main(){
//initialization
float a1,a2;
//display the message
cout<<"Enter the first number: ";
cin>>a1; //store the value
cout<<"Enter the second number: ";
cin>>a2; //store the value
//display the calculation result
cout<<"The sum is: "<<a1+a2<<endl;
cout<<"The Subtraction is: "<<a1-a2<<endl;
cout<<"The product is: "<<a1*a2<<endl;
cout<<"The Quotient is: "<<a1/a2<<endl;
}
Explanation:
Create the main function and declare the two variables of float but we can enter the integer as well.
display the message on the screen and then store the input enter by the user into the variable using the cin instruction.
the same process for second input as well, display the message and store the input.
after that, print the output of the calculation. the operator '+' is used to add the two numbers like a1+a2, it adds the number stored in the variable.
similarly, the subtraction operator is '-', product '*' and quotient operator '/'.
and finally, we get the desired output.
Answer:
1. Get the number
2. Declare a variable to store the sum and set it to 0
3. Repeat the next two steps till the number is not 0
4. Get the rightmost digit of the number with help of remainder ‘%’ operator by dividing it with 10 and add it to sum.
5. Divide the number by 10 with help of ‘/’ operator
6. Print or return the sum
# include<iostream>
using namespace std;
/* Function to get sum of digits */
class gfg
{
public:
int getSum(float n)
{
float sum = 0 ;
while (n != 0)
{
sum = sum + n % 10;
n = n/10;
}
return sum;
}
};
//driver code
int main()
{
gfg g;
float n = 687;
cout<< g.getSum(n);
return 0;
}

Explanation:
My laptop's current screen resolution is (1366 by 768 recommended). When you change your screen resolution, your pc automatically suggests the recommended screen resolution that helps you to view more information on your screen and enable you to fit the most information on the screen while still being able to read the display.
To change the screen resolution, you need to go through from the following steps:
Answer:
Validity
Explanation:
Personnel Selection encompasses all the processes and methods involved in the selection of workers. The purpose of personnel selection is to determine the best candidate for the job and in so doing the recruiting organization must play by the rules laid down by the government for recruitment. Validity refers to the relationship between interviews and excellent performance at the job.
Validity implies that the method of selection must meet up to a standard criterion. This standard criterion is the expected job performance required of the potential employee. Different interview types (such as job-related, situational, and psychological) have different validity levels.
