C++ Write an expression to access the last character of a string class object str (not C-string)

Answers

Answer 1

Strings in C++ are represented by arrays of characters. The end of the string is marked with a special character, the null character

In C++, how do I retrieve the final character of a string?

To acquire a reference to the string’s last character, use string. Back(). The final character of the string is also the first character of the reversed string, hence string.rbegin() returns an iterator to the last character. The initial character in a string appears at index zero, while the last character appears at index length of string-1.

// string::back

#include <iostream>

#include <string>

Int main ()

{

 Std::string str (“hello world.”);

 Str.back() = ‘!’;

 Std::cout << str << ‘\n’;

 Return 0;

}

You are a new salesperson at a large software manufacturing firm. It is three weeks from the end of the sales quarter and you and your sales manager are sitting pretty—you have both already met your sales quota for the quarter. In addition, you just closed another deal with a new customer for $100,000 of software and customer service. This order would put you way over your sales quota for the current quarter. Your manager suggests that you hold this new order so it gets recorded against next quarter. She explains that because sales during the next three months tend to slow down, salespeople frequently miss their quotas and associated sales bonuses for that quarter. Holding this large order to next quarter would help you get an excellent start and almost guarantee that you meet your quota. What would you do?

A data science experiment you are conducting has retrieved two historical observations for the price of Bitcoin(BTC) on December 2, 2017 of 11234 and 12475. Create a Python script that stores these two historicalobservations in a list variable namedbtcdec1.Your data science experiment requires four additional data tasks. The first task is to use the listappend()method to add the BTC price of 14560 to the listbtcdec1. The second task is to create a new empty listnamedbtcdec2and append the BTC prices of 15630, 12475, and 14972. The third task required you to usethe listextend()method to add the contents ofbtcdec2into the listbtcdec1. The fourth and final taskrequires you to use the listsort()method of the listbtcdec1to sort the items in the newly extended list,then use theprintstatement to output the content of listbtcdec1to the Python console.Starter code:_______.

Answers

Answer:

Following are the code to this question:

btcdec1=[11234, 12475] #defining a list btcdec1 that holds two integer values  

btcdec1.append(14560)#using append method to add value in btcdec1 list

btcdec2=[]#defining an empty list btcdec2

btcdec2.append(15630)#using append method to add value in btcdec2 list

btcdec2.append(12475)#using append method to add value in btcdec2 list

btcdec2.append(14972)#using append method to add value in btcdec2 list

btcdec1.extend(btcdec2)#using the extend method to add value list into btcdec1

btcdec1.sort()#using sort method to arrange value in ascending order

print(btcdec1)#print list btcdec1

Output:

[11234, 12475, 12475, 14560, 14972, 15630]

Explanation:

In this code a list "btcdec1" is declared, which holds two integer variables, in the next step, it uses the append method to add another element into the list.

In the next step, another empty list "btcdec2" is declared, which uses the append method to hold the integer element, and uses the extend and sort method to add the second list into the first one and then sort the whole list and print its values.

You work at a computer repair store. A customer wants you to install a new sound card into his computer to run his home theater system. Currently, the computer uses the sound card built into the motherboard. You need to upgrade the computer with a better sound card that installs into an expansion card slot. Your task is to complete the following:

a. Install the sound card with the optical output.
b. View the Details for each card to identify the card with an optical audio connector.
c. Boot into the BIOS and disable the onboard sound card.
d. Boot into Windows and verify that the new sound card is recognized and the onboard sound card does not appear in Device Manager.

Answers

Answer:

Explanation:

The following tasks are needed to complete the installation of the sound card so that it is fully usable.

a. and b. : First, you need to slot the sound card into a pci-e slot in the motherboard and connect the optical cable to the back of the sound card. You can look at the back of the card or the box to see if it has an optical audio connector slot.

c. Next you can boot into the Bios to disable the onboard sound card. Each motherboard is different but the usual way of entering the bios is pressing F12 when turning on the PC. Then navigate to the motherboard options tab/menu and turn off the onboard sound.

d. Finally, turn on the PC, log in and at the bottom left search bar type in Device Manager. Next navigate to sound, video and game controllers and make sure the new sound card is being detected.

The objective of this task is to use Scapy to estimate the distance, in terms of number of routers, between your VM and a selected destination. This is basically what is implemented by the traceroute tool. In this task, we will write our own tool. The idea is quite straightforward: just send a packet (any type) to the destination, with its Time-To-Live (TTL) field set to 1 first. This packet will be dropped by the first router, which will send us an ICMP error message, telling us that the time-to-live has exceeded. That is how we
This project is based on SEED labs by Wenliang Du, Syracuse University.
get the IP address of the first router. We then increase our TTL field to 2, send out another packet, and get the IP address of the second router. We will repeat this procedure until our packet finally reach the destination. It should be noted that this experiment only gets an estimated result, because in theory, not all these packets take the same route (but in practice, they may within a short period of time). The code in the following shows one round in the procedure
a = IP()
a.dst '1.2.3.4
a.ttl = 3
b = ICMP()
send (a/b)
If you are an experienced Python programmer, you can write your tool to perform the entire procedure automatically. If you are new to Python programming, you can do it by manually changing the TTL field in each round, and record the IP address based on your observation from Wireshark. Either way is acceptable, as long as you get the result
Task: Sniffing and-then Spoofing
In this task, you will combine the sniffing and spoofing techniques to implement the following sniff- and-then-spoof program. You need two VMs on the same LAN. From VM A, you ping an IP X. This will generate an ICMP echo request packet. If X is alive, the ping program will receive an echo reply, and print out the response. Your sniff-and-then-spoof program runs on VM B, which monitors the LAN through packet sniffing. Whenever it sees an ICMP echo request, regardless of what the target IP address is, your program should immediately send out an echo reply using the packet spoofing technique. Therefore, regard-less of whether machine X is alive or not, the ping program will always receive a reply, indicating that X is alive. You need to use Scapy to do this task. In your report, you need to provide evidence to demonstrate that your technique works.
