Answer:
B. the noise (i.e., noise floor) in the signal-to-noise ratio, is a wideband noise product that is predominated by thermal noise.
Explanation:
Sound can be defined as mechanical waves that are highly dependent on matter for their propagation and transmission. Sound travels faster through solids than it does through either liquids or gases.
Signal-to-noise ratio (SNR) is simply the ratio of signal power to noise power or the ratio of desired information to the undesired signal. SNR doesn't have a unit i.e it is a unitless quantity.
Generally, the higher the signal-to-noise ratio (SNR), the better would be the quality of a signal.
Additionally, a negative signal-to-noise ratio (SNR) in decibel form simply means that the signal power is lesser than the noise power.
Hence, the correct statement regarding the signal-to-noise ratio (SNR) is that the noise (i.e., noise floor) in the signal-to-noise ratio, is a wideband noise product that is predominated by thermal noise.
Note: noise can be defined as an unwanted disturbance or undesired signal present in an electrical signal.

Sentence Deobfuscate Name this file deobfuscate.cpp Hints: Don’t overthink this problem. Prompt the user to enter a collection of sentence words (i.e., words in the sentence), with the spaces removed (i.e., the obfuscated sentence) and with words that are less than ten (10) letters each. Then prompt the user to enter a sequence of numbers that represent the length of each corresponding sentence word (i.e. the deobfuscated details). Output the deobfuscated sentence. Convert char c to int by subtracting 48 (‘0’) from c.
Sample Execution:
Please enter obfuscated sentence: Thisisasentence
Please enter deobfuscation details: 4218
Deobfuscated sentence: This is a sentence
Answer:
In C++:
#include <iostream>
using namespace std;
int main(){
string text,lengt;
cout<<"Please enter obfuscated sentence: "; cin>>text;
cout<<"Please enter deobfuscation details: "; cin>>lengt;
string t1, t2;
int kount = 0;
for(int i = 0;i<lengt.length();i++){
kount+=(int)(lengt[i]-'0');
t1 = text.substr(0, kount);
t2 = text.substr(kount, text.length()-1);
text = t1 +" "+ t2;
kount++; }
cout<<"Deobfuscated sentence: "<<text;
return 0; }
Explanation:
This declares the text and the deobfuscation details as string
string text,lengt;
This prompts for the sentence
cout<<"Please enter obfuscated sentence: "; cin>>text;
This prompts for the details
cout<<"Please enter deobfuscation details: "; cin>>lengt;
t1 and t2 are declared as string. They are used to split the texts into 2 parts
string t1, t2;
This declares and initializes a count variable to 0
int kount = 0;
This iterates through the deobfuscation details
for(int i = 0;i<lengt.length();i++){
This gets each deobfuscation character
kount+=(int)(lengt[i]-'0');
The next two instructions splits the text into 2
This gets from 0 to kount.
t1 = text.substr(0, kount);
This gets from kount to the last index
t2 = text.substr(kount, text.length()-1);
The new string or sentence is calculated here
text = t1 +" "+ t2;
The kount variable is incremented by 1
kount++; } The loop ends here
This prints the new sentence
cout<<"Deobfuscated sentence: "<<text;

Which statement in main() generates an error?
public class Players {
public void setName(String newName) { … }
public void setAge(int newAge) { … }
};
public class SoccerPlayers extends Players {
public void setDetails(String newName) { … }
public String getLeague() { … }
};
public static void main(String args[]) {
String leagueName;
Players newPlayers = new Players();
SoccerPlayers playerObject = new SoccerPlayers();
playerObject.setName("Jessica Smith");
playerObject.setAge(21);
leagueName = newPlayers.getLeague(); }
A. SoccerPlayers playerObject=new SoccerPlayers(); An object of a derived class cannot be created.
B. playerObject.setName("Jessica Smith"); setName() is not declared in SoccerPlayers.
C. leagueName=newPlayers.getLeague(); getLeague() is not a member of Players.
D. Players newPlayers=new Players(); An object of a base class cannot be created.
Answer:
C. leagueName=newPlayers.getLeague(); getLeague() is not a member of Players.
Explanation:
The main method in this code will case an error when trying to run the following line of code...
leagueName=newPlayers.getLeague();
This is because the method getLeague() is being called on a Player object which takes all of its methods from the Player class. Since getLeague() is not a method located in the player class then it cannot be called by an object from that class. Especially since the Player class does not extend to the SoccerPlayers class where the getLeague() method is actually located. Instead, it is the SoccerPlayers class which extends the Players class as its parent class.
C++ "Simon Says" is a memory game where "Simon" outputs a sequence of 10 characters (R, G, B, Y) and the user must repeat the sequence. Create a for loop that compares the two strings starting from index 0. For each match, add one point to userScore. Upon a mismatch, exit the loop using a break statement. Assume simonPattern and userPattern are always the same length.
Ex: The following patterns yield a userScore of 4:
Ex: The following patterns yield a userScore of 9:
simonPattern: RRGBRYYBGY
userPattern: RRGBBRYBGY
Result: Can't get test 2 to occur when userScore is 9
Testing: RRGBRYYBGY/RRGBBRYBGY
Your value: 4
Testing: RRRRRRRRRR/RRRRRRRRRY
Expected value: 9
Your value: 4
Tests aborted.
Answer:
In C++:
#include <iostream>
using namespace std;
int main(){
int userScore = 0;
string simonPattern, userPattern;
cout<<"Simon Pattern: "; cin>>simonPattern;
cout<<"User Pattern: "; cin>>userPattern;
for (int i =0; i < simonPattern.length();i++){
if(simonPattern[i]== userPattern[i]){
userScore++; }
else{ break; }
}
cout<<"Your value: "<<userScore;
return 0;
}
Explanation:
This initializes user score to 0
int userScore = 0;
This declares simonPattern and userPattern as string
string simonPattern, userPattern;
This gets input for simonPattern
cout<<"Simon Pattern: "; cin>>simonPattern;
This gets input for userPattern
cout<<"User Pattern: "; cin>>userPattern;
This iterates through each string
for (int i =0; i < simonPattern.length();i++){
This checks for matching characters
if(simonPattern[i]== userPattern[i]){
userScore++; }
This breaks the loop, if the characters mismatch
else{ break; }
}
This prints the number of consecutive matches
cout<<"Your value: "<<userScore;

Explain, step by step the process required to carry out drive error correction (disk check) on Windows 10
Explanation:
Disk Error Checking in Windows 10
In Windows 8, Microsoft has redesigned chkdsk utility – the tool for detecting and fixing disk corruption. In Windows 8, Microsoft introduced a file system called ReFS, which does not require an offline chkdsk to repair corruptions – as it follows a different model for resiliency and hence does not need to run the traditional chkdsk utility.
The disk is periodically checked for file system errors, bad sectors, lost clusters, etc., during Automatic Maintenance and you now no longer need to really go and run it. In fact, Windows 8 now even exposes the state of the file-system and disk via the Action Center or under the Drive properties in File Explorer. If potential errors are found, you will be informed about it. You can continue to use the computer, while the scan is carried out in the background. If errors are found, you may be prompted via a notification to restart your computer.
Read: How to cancel ChkDsk in Windows.
Windows found errors on this drive that need to be repaired
At times you may see a message – Windows found errors on this drive that need to be repaired. If you see it, you may want to manually run a scan. Earlier you had to schedule Disk Error Checking for the system drive and for drives which had files or processes or folders opened. In Windows 10/8, error checking starts right away, even on the system drive – and it longer needs to be scheduled at start-up. Only if some errors are found, will you have to restart to let Windows 10/8 fix the errors.
How to run CHKDSK in Windows 10
To begin the scan, right-click on the Drive which you wish to check and select Properties. Next, click on Tools tab and under Error-checking, click on the Check button. This option will check the drive for file system errors.
If the system detects that there are errors, you will be asked to check the disk. If no errors are found, you will see a message – You don’t need to scan this drive. You can, nevertheless, choose to check the drive. Click on Scan drive to do so.
how are headers and footers are useful in presentation
Answer:
Explanation:
PowerPoint is a software that allows user to create headers as well as footers which are information usually appears at the top of the slides and the information that appears at the bottom of all slides. Headers and footers are useful when making presentation in these ways:

what is output?
a include <iostreom.h>
void sub (float & x)
{ x + =2;
cout <<" \nx="<<x;
}
اے
void main ()
{ clrser ()
float x = 5.8
cout<<" \nx="<<x'
sob (x);
Cout <<"\nx="<<x
getch ();
}
Answer:
x=5.8
x=7.8
x=7.8
Explanation:
I repaired the code somewhat (see below).
Since x is passed as a reference variable to the sub function, inside sub() the original variable is modified, so the changed value affects the variable declared in main().
If you would remove the & in sub, this wouldn't happen, and the variable in main would keep its value 5.8.
Write a C program that gets 4 integer values from the user, namely, x1, x2, y1, and y2, and then calculates and returns the distance according to the above formula. Use whatever format for entering your data you like. Your program should prompt the user for these values, accept input from the keyboard, and then print out the result. You will have to execute the program four times to cover the test cases below (feel free to use a loop if you want to work ahead). Include a screenshot (or four) that shows the results for the following values: 1) (2,3), (4,5) 2) (4,3), (-6,-5) 3) (-1,3), (4,-2) 4) (-9,-12), (-7, -8)
Answer:
#include <stdio.h>
#include <math.h>
int main(){
float x1,x2,y1,y2,distance;
printf("x1: "); scanf("%f", &x1);
printf("y1: "); scanf("%f", &y1);
printf("x2: "); scanf("%f", &x2);
printf("y2: "); scanf("%f", &y2);
distance = sqrt((x1 - x2)*(x1 - x2) + (y1 - y2)*(y1 - y2));
printf("Distance: %f", distance);
return 0;
}
Explanation:
This line declares all required variable (i.e. the coordinates and the distance)
float x1,x2,y1,y2,distance;
The next four line prompt and get input for the coordinates
printf("x1: "); scanf("%f", &x1);
printf("y1: "); scanf("%f", &y1);
printf("x2: "); scanf("%f", &x2);
printf("y2: "); scanf("%f", &y2);
This calculates the distance
distance = sqrt((x1 - x2)*(x1 - x2) + (y1 - y2)*(y1 - y2));
This prints the calculated distance
printf("Distance: %f", distance);
