Answer:
In the following code, you can see the usage of malloc.
#include <stdio.h>
#include <stdlib.h>
int main(void) {
int* numberPointer1 = NULL;
int* numberPointer2 = NULL;
numberPointer1 = (int *)malloc(sizeof(int *));
numberPointer2 = (int *)malloc(sizeof(int *));
*numberPointer1 = 44;
*numberPointer2 = 99;
printf("numberPointer1 = %d, numberPointer2 = %d\n", *numberPointer1, *numberPointer2);
free(numberPointer1);
free(numberPointer2);
return 0;
}
Explanation:
Malloc allocates memory in the heap according to the input size and returns a pointer to the location where it was allocated, with an extra, it clears all allocated space.

Hands-On Project 15-4 Make Network Cables
Using the tools and skills you learned about in this chapter, practice making a straight-through cable and a crossover cable. Use a cable tester to test both cables. Answer the following questions:
1. Which wiring standard did you use for the straight-through cable? List the pinouts (pin number and wire color) for each of the eight pins on each connector.
2. Will your crossover cable work on a Gigabit Ethernet network? List the pinouts (pin number and wire color) for each of the eight pins on each connector.
Answer:
1. You can use either standard (T-568A or T-568B) - but must keep the standard throughout the installation (can't mix A with B).
The B standard is preferred in the US. A is mostly used overseas (Europe)
For A the proper wiring sequence is:
1 - Orange/White
2 - Orange
3 - Green / White
4 - Blue
5 - Blue / White
6 - Green
7 - Brown / White
8 - Brown
2. Cross over connections use a different pinout for one side of the cable. The second side is wired normally.
Crossover connections are only used for device to device connections. ( as in the case of connecting two NIC cards together directly). They will not work if plugged into a switch or other network device.
Normal side - use the pinout from question #1
Crossover side:
1 Green / White
2 Green
3 Orange / White
4 Brown / White
5 Brown
6 Orange
7 Blue
8 Blue / White

3.3 Code Practice: Question 1
Instructions
Test if a date is a payday based on the day of the month (15th or the 30th).
Sample Run
Enter today's day numerically: 17
Sorry, not a payday.
Enter today's day numerically: 30
It's payday!
please help in python!
Answer:
date = int(input("Enter today's day numerically: "))
if date == 15 :
print("It's payday!")
elif date == 30 :
print("It's payday!")
else:
print("Sorry, not a payday.");
Explanation:
The program illustrates the use of if-conditions
The program in Python where comments are used to explain each line is as follows:
#This gets integer input for day
day = int(input("Enter today's day numerically: "))
#This checks if day is 50 or 30
if day == 15 or day == 30:
#If yes, this prints payday
print("It's payday!")
#If otherwise
else:
#If otherwise, this prints not a payday
print("Sorry, not a payday.")
At the end of the program, the program outputs payday or not a payday; depending on the input from the user

It is common practice not to store user’s password in clear text. However, if an attacker has seized control of the password database, he is likely already capable of modifying any user data on the site as an administrator. Why bother hashing the passwords then?
Answer:
To prevent leakage of user's passwords.
Explanation:
I don't really know the premise of your question, but I assume it is this. If the hacker has access to the user's data, they may have the email address. If they cannot crack the password hash, then they may not attempt to login to the user's accounts on other websites.

Write an expression using Boolean operators that prints "Special number" if special_num is -99, 0, or 44.
Sample output with input: 17
Not special number
Answer:
special_num = int(input())
if special_num == -99 or special_num == 0 or special_num == 44:
print('Special number')
else:
print('Not special number')
Explanation:
#get input
special_num = int(input())
#if function to evaluate true or false(aka Boolean)
if special_num == -99 or special_num == 0 or special_num == 44:
#true evaluation
print('Special number')
#false evaluation
print('Not special number')
The program evaluates the number inputted by a user, checks if it is one of three special numbers and displays the appropriate message. The program is written in python 3 ;
special_num = int(input('enter number : '))
#allows user to input an integer value which is assigned to the variable named special number
if(special_num == -99) or (special_num ==0) or (special_num == 44):
#checks if the inputted value is one of the three special numbers using the assignment operator '==' and 'OR'
print('special number')
# if the condition evaluates to true, display the message ;special number
else :
print('Not a special number')
#if otherwise, display the message, not a special number.

There’s a scientific theory out there that says that our brain uses an algorithm to create our thoughts and it’s called the Theory of Connectivity. This theory suggests that information comes into our brains, is processed, stored, and then results in an output. Does this process sound familiar to you? In what ways do our bodies take in input and respond, sometimes without our control? Give two examples
Answer:
1. Yes, the process sounds familiar to me. It looks like the mechanism of operation of the computer.
2a. Through reflex actions, our bodies take in input and respond sometimes without our control.
b. Two examples are sneezing and the scratch reflex.
Explanation:
The principle of the theory of connectivity which involves the input, processing, storage, and output of results is similar to the workings of the human body which has to accept input from the external surroundings which it processes and provides an output for. Reflex actions are involuntary actions made in response to a stimulus. When the body receives the input, the response is made most times before we are aware of it.
Scratch reflex occurs when the sensory neurons located on the periphery of our skins are activated due to stimuli that could be in the form of touch, an insect bite, etc. Sneezing is another example of a reflex action.
Answer:
The process does sound familiar to me; it is like the mechanism of operation of the computer. Through reflex actions, our bodies take in input and respond sometimes without our control, such as shivering, blinking, and sneezing.

When collecting digital evidence from a crime scene, often the best strategy for dealing with a computer that is powered on is to:
Options:
a. remove the hard drive
b. transport it while running
c. perform a clean shutdown
d. unplug it
Answer:
d. unplug it
Explanation:
Indeed, unplugging the computer often the best strategy for dealing with a computer that is powered on so to preserve (or collect) digital evidence. By so doing it allows the investigator to safely check through the computer found at the crime scene.
However, if the investigator decides to remove the hard drive or performing a clean shutdown, valuable evidence may be lost as a result. Also, transporting it while running isn't going to be a viable option.

Write a java program that accepts the ingredients for a recipe in cups and converts to ounces
Answer:
Explanation:
public static int cupsToOunces (int cups) {
int ounces = cups * 8;
return ounces;
}
This is a very simple Java method that takes in the number of cups in the recipe as a parameter, converts it to ounces, and then returns the number of ounces. It is very simple since 1 cup is equal to 8 ounces, therefore it simply takes the cups and multiplies it by 8 and saves that value in an int variable called ounces.
