Answers
The answer is 1. True, 2. True.
Explanation:
Dynamic memory allocation in C++ requires the use of a pointer to point to the allocated memory. When a program finishes using dynamically allocated memory, it should delete it to free up the memory for future use. Forgetting to delete dynamically allocated memory results in a memory leak, which means that the memory is not released, and it continues to be occupied by the program. This can lead to a shortage of available memory and may cause the program to crash.
Furthermore, forgetting to delete dynamically allocated memory can cause a dangling pointer, which is a pointer that points to memory that has been deallocated. Dereferencing a dangling pointer can result in undefined behavior and can cause the program to crash. Therefore, it is important to always delete dynamically allocated memory when it is no longer needed to avoid memory leaks and dangling pointers. C++ introduced smart pointers, which help avoid memory leaks and dangling pointers by automatically deleting dynamically allocated memory when it goes out of scope.

Keeping your operating system and applications up to date help you to:
fix bugs and address security updates
extend the life of your device's battery
store information about software updates
increase the memory size of your hard drive
Answers
Alright mate
Keeping your operating system and applications up to date is an important aspect of maintaining the security and performance of your device. There are several reasons why keeping your device up to date is important:
Fix bugs and address security updates: Software developers often release updates to fix bugs and address security vulnerabilities that have been discovered in their products. By installing these updates, you can ensure that your device is running smoothly and securely. For example, a security update may patch a vulnerability that could allow an attacker to gain unauthorized access to your device or steal sensitive information.
Extend the life of your device's battery: Updating your device can also help to extend the life of its battery. Newer software versions may include optimizations that reduce the power consumption of your device, which can help to prolong its battery life.
Store information about software updates: Updating your device also allows you to store information about the software updates you've installed. This information can be useful in case you need to troubleshoot an issue or revert to a previous version of the software.
Increase the memory size of your hard drive: Updating your device can also increase the memory size of your hard drive. This is especially true for operating systems, as they often get updates that improve the way they handle memory and disk usage.
It's also important to note that not all updates are created equal, some updates can be considered as "feature" updates that add new functionality to the system, while others are "security" updates that address discovered vulnerabilities.
In general, keeping your device up to date is an important step in maintaining its security and performance. By installing updates in a timely manner, you can help to ensure that your device remains secure and stable, and that you are able to take advantage of new features and improvements as they become available.

a message ____________________ is a fingerprint of the author’s message that is compared with the recipient’s locally calculated hash of the same message.
Answers
A message fingerprint is a unique digital signature that identifies the author's message and is compared to the recipient's locally calculated hash of the same message. This method of verification helps to ensure the authenticity and integrity of the message being sent.
Message fingerprinting is a widespread approach in modern communication networks for preventing unwanted access to data and ensuring that messages have not been tampered with during transit. A hashing technique is used to turn the content of a communication into a unique digital signature before it is transmitted. This signature, or fingerprint, is then delivered to the receiver along with the message.
When the message is received, the recipient's system computes the hash of the message and compares it to the sender's hash to guarantee that they match. If they don't match, it means the communication was tampered with or distorted in route. The communication will be refused in such instances, and the sender will be alerted.
Message fingerprinting is a crucial security measure that is used in various communication technologies such as email, instant messaging, and file-sharing systems. By using message fingerprints, organizations can ensure that their sensitive data remains secure and that their messages are delivered without any tampering or unauthorized access.

add an if branch to complete double_pennies()'s base case. sample output with inputs: 1 10 number of pennies after 10 days: 1024
Answers
The given function is incomplete and needs to be modified to get the correct output. The function name is `double_pennies()` and it is missing an if-else statement.
It takes in two arguments, `num_of_pennies` and `num_of_days`.The function doubles the number of pennies every day and returns the total number of pennies at the end of the given days.
The base case of the function has to be added to get the correct output for lower values of days, so the function looks like this:```def double_pennies(num_of_pennies, num_of_days):
if num_of_days == 0:
return num_of_pennies else:
return double_pennies(num_of_pennies * 2, num_of_days - 1)``
The above code will return the correct output for the given input of 1 and 10 which is:```number of pennies after 10 days: 1024```

Answers
It is important to note that SSL has been superseded by TLS (Transport Layer Security) and is no longer considered a secure protocol. TLS uses a similar process for encrypting data, but with different encryption algorithms and other improvements to security.
The correct order of steps that SSL (Secure Sockets Layer) uses in its coding process is:
Fragmentation: The data is divided into small fragments so that it can be transmitted easily over the network.
Encryption: Each fragment is encrypted using a symmetric encryption algorithm such as AES, 3DES, or RC4. The encryption key is generated using a public-key encryption algorithm such as RSA or Diffie-Hellman.
Compression: The encrypted fragments are compressed using a compression algorithm such as zlib to reduce the size of the data being transmitted.
Transmission: The compressed and encrypted fragments are transmitted over the network.
Reception: The receiver receives the compressed and encrypted fragments and performs the reverse process - decompressing the fragments, decrypting them, and reassembling them into the original data.

A GPIO pin is a type of generic pin whose value may be adjusted to either a high or low voltage level and whose behavior can be defined using software.
A platform-specific collection of GPIO pins is known as a GPIO port. A GPIO can be used to drive a signal high or low when it is set up as an output. Push-pull and open-drain are the two main configuration options for GPIO outputs. An uncommitted digital signal pin on an integrated circuit or electrical circuit board is referred to as a general-purpose input/output (GPIO) and can be controlled by software.

You don't currently have recursive grammar. A recursive grammar would or will have at least one production that (directly or indirectly) invokes itself on the right side. "An endless amount of lower case letters" would be the most appropriate phrase to employ in this situation. Because of this, I would define a lower case string (or whatever) as either nil or a lower case string that is followed by a lower case letter. Your word will then start with an uppercase letter and end with a string of lowercase letters.
