Answer:

The correct answer is option b. "every action on a system is recorded in the kernel log".

Explanation:

Programming using linux kernel log levels is very helpful, because logs can inform about he state of daemon, or inform whether an error has occurred. However, is not true that every action on a system is recorded in the kernel log. Only certain information is found in the kernel log, which gives messages with different levels of severity, being the level 0 the most critical, and level 7 the less critical.

When a Select Case statement executes, the value of the test expression is compared with the values that follow each of the ____

goldenfox [79]

Answer:

Case

Explanation:

In Computer programming, a variable can be defined as a placeholder or container for holding a piece of information that can be modified or edited.

Basically, variable stores information which is passed from the location of the method call directly to the method that is called by the program.

For example, they can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function. Therefore, when you create variables in a function, you can can set the values for their parameters.

A Select Case statement can be defined as a conditional statement that avails software developers or programmers the ability to test a variable by comparing it with a list of values.

In a Select Case statement, each variable is referred to as a Case.

Generally, when a Select Case statement executes, the value of the test expression is compared with the values that follow each of the Case keywords.

Dmitry [639]

Answer:

B. How many programming statements the program contains

Explanation:

If a program is intended to be able to process large amounts of data, then the ability of the program to process larger data sets is heavily affected by

execution time
size of memory the program requires
storage space the program requires as it runs.

The length of the statements the program contains does not much affect program performance.

Given that a function receives three parameters a, b, c, of type double , write some code, to be included as part of the functio

hoa [83]

Answer:

public static void quad(double a, double b, double c) {

double D = (Math.pow(b, 2)) - (4 * a * c);

if (D<0){

System.out.println("no real solutions");

}

Explanation:

The code snippet above implements the function in Java programming language

As required by the question, the line double D = (Math.pow(b, 2)) - (4 * a * c); evaluates b squared" - 4ac and assignes the value to the variable D

An if statement is used to test if D is less than 0, if this is true the message no real solutions is printed

create your own min function that finds the minimum element in a list and use it in a separate function

schepotkina [342]

Answer:

def minfunction(mylist):

min = mylist[0]

for i in mylist:

if i < min:

min = i

print("The minimum is: "+str(min))

def anotherfunction():

mylist = []

n = int(input("Length of list: "))

for i in range(n):

listelement = int(input(": "))

mylist.append(listelement)

minfunction(mylist)

anotherfunction()

Explanation:

This solution is implemented in Python

This defines the min function

def minfunction(mylist):

This initializes the minimum element to the first index element

min = mylist[0]

This iterates through the list

for i in mylist:

This checks for the minimum

if i < min:

... and assigns the minimum to variable min

min = i

This prints the minimum element

print("The minimum is: "+str(min))

This defines a separate function. This separate function is used to input items into the list

def anotherfunction():

This defines an empty list

mylist = []

This prompts user for length of list

n = int(input("Length of list: "))

The following iteration inputs elements into the list

for i in range(n):

listelement = int(input(": "))

mylist.append(listelement)

This calls the minimum function

minfunction(mylist)

The main starts here and this calls the separate function

anotherfunction()
