true/false: string objects have a member function named c str that returns the contents of the object formatted as a null-terminated c-string.

Answers

Answer 1

The len function provides the length of a text string.

How do I null-terminate a string in C?

The null terminated strings are essentially a series of characters, with a single null character (designated by '0') as the final element. The compiler creates null terminated strings when we write a string enclosed in double quotes ("...").

Why are C strings terminated with null?

Because strings in C are simply a list of characters that can be retrieved using a reference to the cfirst haracter. You need some way to know where the end of the string is because a pointer does not have room to retain the length. It was determined in C that a null character would serve as the indicator for this.

are weaknesses in a computer system that reduce its overall security. Vulnerabilities might be flaws in the hardware itself or the software that uses it. A malicious actors, such as an attacker, can use vulnerabilities to breach privilege restrictions and carry out illegal actions on a computer system. An attacker needs at least one tool or technique that really can connect to a system flaw in order to exploit a vulnerability. In this context, the attack surface is another name for vulnerabilities.

(e) It requires O(N) operations to reduce to a set of ordered lists and then O(N2) to combine
all lists.

Answers

The statement that explains correctly the complexity of Bubble Sort is option A.

What is the complexity of Bubble Sort?

Bubble Sort is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements, and swaps them if they are in the wrong order.

The complexity arises from the fact that it requires O(N) operations to reduce the list to a set of ordered lists, as it needs to iterate through the entire list multiple times. After each pass, the largest (or smallest, depending on the sorting order) element "bubbles" to its correct position.

However, combining all the ordered lists together to obtain the final sorted list requires further comparisons and swaps. In the worst-case scenario, when the initial list is in reverse order, each element needs to be compared and potentially swapped with every other element, resulting in O(N²) comparisons.

Therefore, option (e) correctly explains the complexity of Bubble Sort, as it reflects the O(N) operations to reduce the lists and the additional O(N²) operations to combine them."

A computer crashes on average once every 4 months. What is the probability that it will not crash in a period of 4 months?.

Since the computer crashes on average once every 4 months, the probability that it will not crash in a period of 4 months is  75%.

What is the probability  about?

The probability that a computer will not crash in a period of 4 months is equal to the probability that it will crash in a period of 4 months.

The probability of an event occurring is typically represented by a value between 0 and 1, where 0 indicates that the event will not occur, and 1 indicates that the event will occur.

Therefore, If a computer crashes on average once every 4 months, that means that the probability of the computer crashing in any 4-month period is 1/4, or 0.25. So , the probability of the computer not crashing in a 4-month period is:

A screw has 4 threads per centimeter and a circumference of 2 centimeters. What is the mechanical advantage of the screw? 2 4 6 8

Answers

Answer:

M.A = 8

Explanation:

Given the following data;

Circumference = 2cm

Number of threads = 4

To find the mechanical advantage (M.A);

\( Mechanical \; advantage = \frac {Circumference}{Pitch} \)

But, \( Pitch = \frac {1}{number \; of \; threads} \)

\( Pitch = \frac {1}{4} \)

Pitch = 0.25

Substituting the values into the equation, we have;

\( M.A = \frac {2}{0.25} \)

Out of 270 racers who started the marathon, 240 completed the race, 21 gave up, and 9 were disqualified. What percentage did not complete the marathon?

Answers

Approximately 11.11% of the racers did not complete the marathon.

To calculate the percentage of racers who did not complete the marathon, we need to find the total number of racers who did not finish the race. This includes both those who gave up and those who were disqualified.

Total number of racers who did not complete the marathon = Number who gave up + Number who were disqualified = 21 + 9 = 30.

Now, we can calculate the percentage using the following formula:

Percentage = (Number who did not complete / Total number of racers) * 100

Percentage = (30 / 270) * 100 = 11.11%.

Why does IPv4 provide for public, private, and reserved IPv4 addresses? Can a host communicate on its LAN when configured with a public IPv4 address? Does your answer change if the host is configured with a private IPv4 address? Explain.

Answers

IPv4 provides for public, private, and reserved addresses to accommodate different networking needs. Public addresses are globally unique and routable on the internet, while private addresses are for local network communication and not routable on the internet.

IPv4 provides for public, private, and reserved IPv4 addresses to accommodate the different networking requirements of organizations and individuals. Public IPv4 addresses are used for communication over the Internet and are unique and globally routable, meaning that they can be accessed from anywhere in the world. Private IPv4 addresses, on the other hand, are used for communication within a private network, such as a home or office LAN, and are not routable on the Internet.

A host configured with a public IPv4 address can communicate on its LAN, but it will not be able to communicate with other devices on the Internet unless it has been assigned a globally unique public IP address. This is because public IPv4 addresses are limited in number, and the Internet routing infrastructure can only accommodate a finite number of them. If a host is configured with a private IPv4 address, it can communicate with other devices on its LAN, but it will not be able to communicate with devices outside the LAN unless it is connected to the Internet through a router that performs Network Address Translation (NAT) to translate the private IP address to a public IP address.

In conclusion, the use of public, private, and reserved IPv4 addresses allows for flexible network configurations to meet the needs of different types of networks. However, it is important to understand the limitations and requirements of each type of address to ensure proper network communication and security.
