For this project, you have to write 3 functions. C++
1. remove_adjacent_digits. This takes in 2 arguments, a std::vector, and a std::vector of the same size. You need to return a std::vector, where each of the strings no longer has any digits that are equal to, one more, or one less, than the corresponding integer in the 2nd vector.
2. sort_by_internal_numbers. This takes in a single argument, a std::vector, and you need to return a std::vector, which is sorted as if only the digits of each string is used to make a number.
3. sort_by_length_2nd_last_digit. This takes in a std::vector>. It returns a vector of the same type as the input, which is sorted, first by the length of the string in the pair, and if they are the same length, then the second last digit of the int.
See the test cases for examples of each of the above functions.
You need to submit a single file called main.cpp that contains all these functions. You can (and should) write additional functions as well. There is no need for a main function.
No loops (for, while, etc) are allowed. You must use only STL algorithms for this project.

Computers in a LAN are configured to use a symmetric key cipher within the LAN to avoid hardware address spoofing. This means that each computer share a different key with every other computer in the LAN. If there are 100 computers in this LAN, each computer must have at least:
a. 100 cipher keys
b. 99 cipher keys
c. 4950 cipher keys
d. 100000 cipher keys
Answers
Answer:
The correct answer is option (c) 4950 cipher keys
Explanation:
Solution
Given that:
From the given question we have that if there are 100 computers in a LAN, then each computer should have how many keys.
Now,
The number of computers available = 100
The number of keys used in symmetric key cipher for N parties is given as follows:
= N(N-1)/2
= 100 * (100 -1)/2
= 50 * 99
= 4950 cipher keys

All organizational security functions are as follows:
i) Classify any vital data
ii) Analyze of the hazard
iii) Analyze vulnerability
iv) Assess the risk
v) Take the appropriate risk prevention measures.
Explanation:
These methods described the incident that will fit into this business model was its ongoing support and control of its system that involves the improvements and fix bugs. For above-mentioned mechanisms aid in evaluating potential events/attacks and help reduce the risk involved with these, as well as promote network security by reducing the likelihood of any harm. In this case, appropriate monitoring and monitoring should be a must.Write a loop that sets each array element to the sum of itself and the next element, except for the last element which stays the same. Be careful not to index beyond the last element. Ex:
Initial scores: 10, 20, 30, 40
Scores after the loop: 30, 50, 70, 40
The first element is 30 or 10 + 20, the second element is 50 or 20 + 30, and the third element is 70 or 30 + 40. The last element remains the same.
SAMPLE OUTPUT:
#include
int main(void) {
const int SCORES_SIZE = 4;
int bonusScores[SCORES_SIZE];
int i = 0;
bonusScores[0] = 10;
bonusScores[1] = 20;
bonusScores[2] = 30;
bonusScores[3] = 40;
/* Your solution goes here */
for (i = 0; i < SCORES_SIZE; ++i) {
printf("%d ", bonusScores[i]);

printf("\n");
return 0;
}
Answers
Answer:
Replace /* Your solution goes here */ with the following lines of code
for(i = 0;i<SCORES_SIZE-1;i++)
{
bonusScores[i]+=bonusScores[i+1];
}
Explanation:
The above iteration starts from the index element (element at 0) and stops at the second to the last element (last - 1).
Using an iterative variable, i
It adds the current element (element at i) with the next element; element at i + 1.
The full code becomes
#include<iostream>
using namespace std;
int main(void) {
const int SCORES_SIZE = 4;
int bonusScores[SCORES_SIZE];
int i = 0;
bonusScores[0] = 10;
bonusScores[1] = 20;
bonusScores[2] = 30;
bonusScores[3] = 40;
for(i = 0;i<SCORES_SIZE-1;i++)
{
bonusScores[i]+=bonusScores[i+1];
}
/* Your solution goes here */
for (i = 0; i < SCORES_SIZE; ++i) {
printf("%d ", bonusScores[i]);
}
printf("\n");
return 0;
}
See attachment for .cpp file
Answer:int main() {
const int SCORES_SIZE = 4;
int bonusScores[SCORES_SIZE];
int i;
for (i = 0; i < SCORES_SIZE; ++i) {
cin >> bonusScores[i];
}
for (i = 0; i < SCORES_SIZE-1; ++i){
bonusScores[i] += bonusScores[i+1];
}
for (i = 0; i < SCORES_SIZE; ++i) {
cout << bonusScores[i] << " ";
}
cout << endl;
return 0;
}
Explanation: SCORES_SIZE -1 will prevent the for loop from going past the last value in the array. bonusScores[i] += will add the value of bonusScores[i+1] to the original bonusScores[i].
for example, i = 1; 1 < SCORES_SIZE - 1 ; bonusScores[1] += bonusScores[1+1} becomes{ bonusScores[1] + bonusScores{2];

scanf("%d", &digit);
//Check if digit is within range 10 to 100
while(digit<10 || digit >100)

Each contact centre has a varying call volume, contributing to a high operational cost for the company. Universal Containers wants to optimize the cost without compromising customer satisfaction.; What can a consultant recommend to accomplish these objectives?
A. Prioritize customer calls based on their SLA
B. Cross-train agents on both product lines
C. Enable agents to transfer calls to other agents
D. Implement a customer self-service portal
Answers
Answer:
B. Cross-train agents on both product lines
D. Implement a customer self-service portal
Explanation:
Cross-training is a way of teaching employees different aspects of the job so that they can have a measure of flexibility in the discharge of duties. Managers find this approach to be effective as they believe it saves cost and maximizes the usefulness of employees. It also helps to serve and satisfy a wider range of customers.
So for Universal Containers seeking to optimize cost without compromising customer satisfaction while managing two customer service contact centers, an effective way of dealing with the large call volumes is cross-training agents on both product lines so that they can attend to a wider range of customers. Cross-training agents on both product lines would make them more knowledgeable of the services being offered and this would minimize the need to transfer calls as all agents can provide information on the various products.
Implementing a customer self-service portal would also reduce the workload on the customer service agents as customers can access the information they need on their own.

However, the restoration of data takes time, due to the time spent for restoration of initial back up and the incremental.
Differential Back up has very fast back up operation, because it only requires two pieces of back up.This is however slower compare to the Incremental.
The selective back up enable selection of certain type of file or folders for back up.
it can only be used to back up folders only when important data are needed only.Thus the storage capacity is low.
CPD eliminates back up window and reduces the recovery point objective.However, it has issue of compatibility with the resources to back up.,it is also expensive because its solutions are disk based.
Cloud based is affordable and save cost,It is easier to access. it is efficient,it can be access remotely for convenience.
However, Internet sources and some bandwidth must be available for access., always depends on third party providers,There is also problems encountered when switching providers.
Explanation:
Using MARS/MIPS
A) Write a program which increments from 0 to 15 and display results in Decimal on the console
B) Modify above program to increment from 0 to 15 and display results in Hexadecimal on the console
Answers
Answer:
Explanation:
MIPS program which increments from 0 to 15 and display results in Decimal on the console
In this program the user defined procedures print_int and print_eot were used to print the integer values and new line characters(\n) respectively.the mechanisam of the loop is explaine in the comment section of the program.
addi $s0, $0, 0
addi $s1, $0, 15
print_int:
li $v0, 1 # system call to print integer
syscall
jr $ra # return
print_eol: # prints "\n"
li $v0, 4
la $a0, linebrk
syscall
jr $ra # return
main: . . .
li $a0, 0 # print 0
jal print_int # print value in $a0
loop: move $a0, $s0 # print loop count
jal print_int
jal print_eol # print "\n" character
addi $s0, $s0, 1 # increment loop count by 1
ble $s1, $s0, loop # exit if $s1<$s0
beq $s0, $0, end
end:
MIPS progam to increment from 0 to 15 and display results in Hexadecimal on the console
this program is slightly differed from the previous program in this program the system call issued in print_int is implemented with a system call that prints numbers in hex.
addi $s0, $0, 15
addi $s1, $0, 0
print_int:
li $v0,34 # syscall number for "print hex"
syscall # issue the syscall
jr $ra # return
print_eol: # prints "\n"
li $v0, 4
la $a0, linebrk
syscall
jr $ra # return
main: . . .
li $a0, 0 # print 0
jal print_int # print value in $a0
loop: move $a0, $s0 # print loop count
jal print_int
jal print_eol # print "\n" character
addi $s0, $s0, 1 # increment loop count by 1
ble $s1, $s0, loop # exit if $s0>$s1
beq $s0, $0, end

. . .
}
void fun1(void) {
int b, c, d;
. . .

Given the following calling sequences and assuming that dynamic scoping is used, what variables are visible during execution of the last function called? Include with each visible variable the name of the function in which it was defined
a. main calls funl; funl calls fun2; fun2 calls fun3
b. main calls fun1; fun1 calls fun3
c. main calls fun2; fun2 calls fun3; fun3 calls funl
d. main calls fun1; funl calls fun3; fun3 calls fun2.
Answers
Answer:
In dynamic scoping the current block is searched by the compiler and then all calling functions consecutively e.g. if a function a() calls a separately defined function b() then b() does have access to the local variables of a(). The visible variables with the name of the function in which it was defined are given below.
Explanation:
a. main calls fun1; fun1 calls fun2; fun2 calls fun3
Solution:
Visible Variable: d, e, f Defined in: fun3Visible Variable: c Defined in: fun2 ( the variables d and e of fun2 are not visible)Visible Variable: b Defined in: fun1 ( c and d of func1 are hidden)Visible Variable: a Defined in: main (b,c are hidden)b. main calls fun1; fun1 calls fun3
Solution:
Visible Variable: d, e, f Defined in: fun3 Visible Variable: b, c Defined in: fun1 (d not visible)Visible Variable: a Defined in: main ( b and c not visible)c. main calls fun2; fun2 calls fun3; fun3 calls fun1
Solution:
Visible Variable: b, c, d Defined in: fun1 Visible Variable: e, f Defined in: fun3 ( d not visible)Visible Variable: a Defined in: main ( b and c not visible)Here variables c, d and e of fun2 are not visible .
d. main calls fun1; fun1 calls fun3; fun3 calls fun2
Solution:
Visible Variable: c, d, e Defined in: fun2Visible Variable: f Defined in: fun3 ( d and e not visible)Visible Variable: b Defined in: fun1 ( c and d not visible)Visible Variable: a Defined in: main ( b and c not visible)Let K(x, y) denote the statement "x knows y" and D denote the domain of all people. Express the following English sentences as a quantified proposition using the definitions above:
1. Everybody knows somebody.
2. There is somebody that no one knows.
3. There is no one who knows everybody
Answers
Answer:
Given: K(x,y) denotes statement:
"x knows y"
D denote domain of all people.
Explanation:
1. Everybody knows somebody.
Solution:
∀x∈D ∃y∈D : K(x, y)
∀ means for all. Here it is used for Everybody.
∃ means there exists some. Here it represents Somebody.
∈ means belongs to . Both x and y belongs to the domain D of all people.
2. There is somebody that no one knows.
Solution:
∀x∈D ∃y∈D : ¬K(x, y)
∀ means for all. ∃ means there exists some. ∈ means belongs to both x and y belongs to the domain D of all people.¬ this is negation sign which means not K(x,y). So the negation of everybody knows somebody can be expressed as there is somebody that no one knows.
3. There is no one who knows everybody
Solution:
This can be represented in both the ways below.
∀ y∈D ∃ x∈D : K(x, y)
∀ means for all. ∃ means there exists some. ∈ means belongs to both x and y belongs to the domain D of all people.
∀x∈D ∀y∈D : ¬K(x, y)
∀ means for all. The negation shows that there is no one who knows everybody.
The Fast Freight Shipping Company charges the following rates for different package weights:
2 pounds or less: $1.50
over 2 pounds but not more than 6 pounds: $3.00
over 6 pounds but not more than 10 pounds: $4.00
over 10 pounds: $4.75
Write a program that asks the user to enter the weight of a package and then displays the shipping charges. The program should also do "Input Validation" that only takes positive input values and show a message "invalid input value!" otherwise.
Answers
Answer:
import java.util.Scanner;
public class ShippingCharge
{
static double wt_2=1.50;
static double wt_6=3;
static double wt_10=4;
static double wt_more=4.75;
static double charge;
static double weight;
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
do
{
System.out.print("Enter the weight of the package: ");
weight = sc.nextDouble();
if(weight<=0)
System.out.println("Invalid input value!");
}while(weight<=0);
if(weight<=2)
charge=wt_2;
else if(weight<=6 && weight>2)
charge=wt_6;
else if(weight<=10 && weight>6)
charge=wt_10;
else
charge=wt_more;
System.out.println("Shipping charges for the entered weight are $"+charge);
}
}
OUTPUT
Enter the weight of the package: 0
Invalid input value!
Enter the weight of the package: 4
Shipping charges for the entered weight are $3.0
Explanation:
1. The variables to hold all the shipping charges are declared as double and initialized.
static double wt_2=1.50;
static double wt_6=3;
static double wt_10=4;
static double wt_more=4.75;
2. The variable to hold the user input is declared as double.
static double charge;
static double weight;
3. The variable to hold the final shipping charge is also declared as double.
4. Inside main(), an object of Scanner class is created. This is not declared static since declared inside a static method, main().
Scanner sc = new Scanner(System.in);
5. Inside do-while loop, user input is taken until a valid value is entered.
6. Outside the loop, the final shipping charge is computed using multiple if-else statements.
7. The final shipping charge is then displayed to the user.
8. All the code is written inside class since java is a purely object-oriented language.
9. The object of the class is not created since only a single class is involved.
10. The class having the main() method is declared public.
11. The program is saved with the same name as that of the class having the main() method.
12. The program will be saved as ShippingCharge.java.
13. All the variables are declared as static since they are declared outside main(), at the class level.
