Answer:
b. Try to convince the owner of the computer to give you to decryption key/password.
Explanation:
Encrypted hard drives have maximum security and high data protection. to access them you need to enter a password to unlock them.
The image filtering technique is a method that serves to selectively highlight information contained in an image, for which it does not work.
The encryption algorithm is a component used for the security of electronic data transport, not to access data on an encrypted hard drive.
The encryption key is used in encryption algorithms to transform a message and cannot be exposed by disconnecting the hard drive from its power source.
is brainly down? Cant search anything
write the following function so that it returns the same result, but does
not increment the variable ptr. Your new program must not use anysquare brackets, but must use an integer variable to visit each double in the array. You may eliminate any unneeded variable.
double computeAverage(const double* scores, int nScores)
{
const double* ptr = scores;
double tot = 0;
while (ptr != scores + nScores)
{
tot += *ptr; } ptr++;
}
return tot/nScores;
b. Rewrite the following function so that it does not use any square brackets (not even in the parameter declarations) but does use the integervariable k. Do not use any of the functions such as strlen, strcpy, etc.
// This function searches through str for the character chr.
// If the chr is found, it returns a pointer into str where
// the character was first found, otherwise nullptr (not found).
const char* findTheChar(const char str[], char chr)
{
for(intk=0;str[k]!=0;k++)
if (str[k] == chr)
}
return &str[k];
return nullptr;
}
c. Now rewrite the function shown in part b so that it uses neither square brackets nor any integer variables. Your new function must not use any local variables other than the parameters.
Answer:
Explanation:
a.
// Rewriting the given function without using any square brackets
double computeAverage(const double* scores, int nScores)
{
const double* ptr = scores;
double tot = 0;
int i;//declaring integer variable
for(i=0;i<nScores;i++)
{
//using an integer variable i to visit each double in the array
tot += *(ptr+i);
}
return tot/nScores;
}
b.
// Rewriting the given function without using any square brackets
const char* findTheChar(const char* str, char chr)
{
for(int k=0;(*(str+k))!='\0';k++)
{
if ((*(str+k)) == chr)
return (str+k);
}
return nullptr;
}
c.
//Now rewriting the function shown in part b so that it uses neither square brackets nor any integer variables
const char* findTheChar(const char* str, char chr)
{
while((*str)!='\0')
{
if ((*str) == chr)
return (str);
str++;
}
return nullptr;
}
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.

The common field cricket chirps in direct proportion to the current temperature. Adding 40 to the number of times a cricket chirps in a minute, then dividing by 4, gives us the temperature (in Fahrenheit degrees). Write a program that accepts as input the number of cricket chirps in fifteen seconds, then outputs the current temperature
Answer:
This program is written in Java programming language;
First, you should understand that:
The formula given in the question implies that the current temperature can only be calculated using measurement of time in minutes;
Given that the number of chirps is directly proportional to the temperature.
If the cricket made n chirps in 15 seconds, it will make n * (60/15) chirps in 1 minutes;
n * (60/15) = n * 4
Base on this analysis, the program is as follows
import java.util.*;
public class cricket
{
public static void main(String []args)
{
//Declare number of chips in 1 minutes
int num;
Scanner input = new Scanner(System.in);
//Prompt user for input
System.out.print("Number of chirps (in 15 seconds): ");
num = input.nextInt();
//Calculate temperature (multiply temperature by 4 to get number of chirps in minutes
double temp = (num * 4+ 40)/4;
//Print temperature
System.out.print("Current Temperature = "+temp+" F");
}

Assume passwords are selected from four character combinations of 26 lower case alphabetic characters. Assume an adversary is able to attempt passwords at a rate of 1 per second. Assuming feedback to the adversary flagging an error as each incorrect character is entered, what is the expected time to discover the correct password
Answer:
Given:
Passwords are selected from 4 characters.
Character combinations are 26 lower case alphabetic characters.
Passwords attempts by adversary is at rate of 1 second.
To find:
Expected time to discover the correct password
Explanation:
Solution:
4 character combinations of 26 alphabetic characters at the rate of one attempt at every 1 second = 26 * 4 = 104
So 104 seconds is the time to discover the correct password. However this is the worst case scenario when adversary has to go through every possible combination. An average time or expected time to discover the correct password is:
13 * 4 = 52
You can also write it as 104 / 2 = 52 to discover the correct password. This is when at least half of the password attempts seem to be correct.

Explanation:
Type a statement using srand() to seed random number generation using variable seedVal. Then type two statements using rand() to print two random integers between (and including) 0 and 9. End with a newline. Ex: 5 7 Note: For this activity, using one statement may yield different output (due to the compiler calling rand() in a different order). Use two statements for this activity. Also, after calling srand() once, do not call srand() again. (Notes)
GIVEN:
#include
#include // Enables use of rand()
#include // Enables use of time()
int main(void) {
int seedVal = 0;
/* Your solution goes here */
return 0;
}
2). Type two statements that use rand() to print 2 random integers between (and including) 100 and 149. End with a newline. Ex:
101
133
Note: For this activity, using one statement may yield different output (due to the compiler calling rand() in a different order). Use two statements for this activity. Also, srand() has already been called; do not call srand() again.
GIVEN:
#include
#include // Enables use of rand()
#include // Enables use of time()
int main(void) {
int seedVal = 0;
seedVal = 4;
srand(seedVal);
/* Your solution goes here */
return 0;
}
Answer:
1. The solution to question 1 is as follows;
srand(seedVal);
cout<<rand()%10<<endl;
cout<<rand()%10<<endl;
2. The solution to question 2 is as follows
cout<<100+rand()%50 <<endl;
cout<<100+rand()%50 <<endl;
Explanation:
The general syntax to generate random number between interval is
Random Number = Lower Limit + rand() % (Upper Limit - Lower Limit + 1)
In 1;
The solution starts by calling srand(seedVal);
The next two statements is explained as follows
To print two random integers between intervals of 0 and 9 using rand()"
Here, the lower limit = 0
the upper limit = 9
By substituting these values in the formula above; the random number will be generated as thus;
Random Number = 0 + rand() % (9 - 0 + 1)
Random Number = 0 + rand() % (10)
Random Number = rand() % (10)
So, the instruction to generate the two random variables is rand() % (10)
2.
Similar to 1 above
To print two random integers between intervals of 100 and 149 using rand()"
Here, the lower limit = 100
upper limit = 149
By substituting these values in the formula above; the random number will be generated as thus;
Random Number = 100 + rand() % (149 - 100 + 1)
Random Number = 100 + rand() % (50)
So, the instruction to generate the two random variables is 100 + rand() % (50)
Suppose that class OrderList has a private attribute double cost[100] which hold the cost of all ordered items, and a private attributes int num_of_items which hold the number of items ordered. For example, if num_of_items is 5, then cost[0], cost[1], ..., cost[4] hold the cost of these 5 items. Implement the member function named total_cost which returns the total cost of this OrderList.
Answer:
OrderList.java
public class OrderList { private double cost[]; private int num_of_items; public OrderList(){ cost = new double[100]; } public double total_cost(){ double total = 0; for(int i=0; i < num_of_items; i++){ total += cost[i]; } return total; } }Main.java
public class Main { public static void main(String[] args) { OrderList sample = new OrderList(); double totalCost = sample.total_cost(); } }Explanation:
Firstly, define a class OrderList with two private attributes, cost and num_of_items (Line 1-3). In the constructor, initialize the cost attribute with a double type array with size 100. Next, create another method total_cost() to calculate the total cost of items (Line 9-15). To implement the total_cost member function, create an OrderList instance and use that instance to call the total_cost() and assign it to totalCost variable.

a. A programmer wrote a software delay loop that counts the variable (unsigned int counter) from 0 up to 40,000 to create a small delay. If the user wishes to double the delay, can they simply increase the upperbound to 80,000?
b. If the code contains a delay loop and we noticed that no delay is being created at run-time. What should we suspect during debugging?
Answer:
Explanation:
The objective here is to determine if the programmer can simply increase the upperbound to 80,000.
Of course Yes, The programmer can simply increase the delay by doubling the upperbound by 80000. The representation can be illustrated as:
( int : i = 0; i < 40,000; i ++ )
{
// delay code
}
Which can be modified as:
( int : i = 0; i < 80,000; i ++ )
{
// delay code
}
b) If the code contains a delay loop and we noticed that no delay is being created at run-time. What should we suspect during debugging?
Assuming there is no delay being created at the run-time,
The code is illustrated as:
For ( int : i = 0 ; i < 0 ; i ++ )
{
// delay code which wont
//execute since code delay is zero
}
we ought to check whether the loop is being satisfied or not. At the Initial value of loop variable, is there any break or exit statement is being executed in between loop. Thus, the aforementioned delay loop wont be executed since the loop wont be executed for any value of i.
C++ Problem: In the bin packing problem, items of different weights (or sizes) must be packed into a finite number of bins each with the capacity C in a way that minimizes the number of bins used. The decision version of the bin packing problem (deciding if objects will fit into <= k bins) is NPcomplete. There is no known polynomial time algorithm to solve the optimization version of the bin packing problem. In this homework you will be examining three greedy approximation algorithms to solve the bin packing problem.
- First-Fit: Put each item as you come to it into the first (earliest opened) bin into which it fits. If there is no available bin then open a new bin.
- First-Fit-Decreasing: First sort the items in decreasing order by size, then use First-Fit on the resulting list.
- Best Fit: Place the items in the order in which they arrive. Place the next item into the bin which will leave the least room left over after the item is placed in the bin. If it does not fit in any bin, start a new bin.
Implement the algorithms in C++. Your program named bins.cpp should read in a text file named bin.txt with multiple test cases as explained below and output to the terminal the number of bins each algorithm calculated for each test case. Example bin.txt: The first line is the number of test cases, followed by the capacity of bins for that test case, the number of items and then the weight of each item. You can assume that the weight of an item does not exceed the capacity of a bin for that problem.

. The total processing speed of microprocessors (based on clock rate and number of circuits) is doubling roughly every year. Today, a symmetric session key needs to be 100 bits long to be considered strong. How long will a symmetric session key have to be in 30 years to be considered strong?
Answer:
130 bits
Explanation:
If the length of a key = N bits
Total number of key combinations = [tex]\frac{2^{N} }{2}[/tex]
For a key length of 100, the total number of key combinations will be [tex]\frac{2^{100} }{2} = 2^{99}[/tex] combinations. This is a whole lot and it almost seems impossible to be hacked.
The addition of one bit to the length of the symmetric key in 1 year is sufficient to make the key strong, because even at double its speed, the processor can still not crack the number of combinations that will be formed.
Therefore, if a bit is added to the key length per year, after 30 years, the length of the symmetric session key will be 130 bits.

a. Full-interruption
b. Desk check
c. Simulation
d. Structured walk-through
Answer:Full-interruption--A
Explanation: The Full-interruption is one of the major steps for a Disaster Recovery Plan, DRP which ensures businesses are not disrupted by saving valuable resources during a disaster like a data breach from fire or flood.
Although expensive and very risky especially in its simulation of a disruption, this thorough plan ensures that when a disaster occurs, the operations are shut down at the primary site and are transferred to the recovery site allowing Individuals follow every procedure, ranging from the interruption of service to the restoration of data from backups, also with the notification of appropriate individuals.

int store; // variable declaration
store = sum(32,15,"san"); // Calling of sum()
System.out.println(" TheValue returned by sum() : "+store); // display
}
Explanation:
Following are the description of the above statement
Here is the name of function is sum() In the sum() function definition there are 3 parameter in there signature i.e two "int" type and 1 is "string" type .In the main function we declared the variable store i,e is used for storing the result of sum() it means it storing the result of value that is returning from the definition of sum() function .After that calling the function by there name and passing three parameter under it sum(32,15,"san"); and store in the "store" variable.Finally print the value by using system.out.println ().What is a digital security risks?
