Why are the extraction and insertion operators always implemented as friends of the class rather than as members of the class?a. Because the first parameter must be the stream object.b. They don't, they could be membersc. Because they return a referenced. Because the stream is passed by reference.

The resultant chain after adding the nodes "L", "A", "R", "X", "J" using the provided add method would look like option B: "J", "X", "R", "A", "L". The resulting chain is "J", "X", "R", "A", "L".

The add method adds each new node to the beginning of the chain by creating a new Node with the given data and pointing its next reference to the first node of the existing chain. The firstNode reference is then updated to point to the newly created node. Therefore, the nodes are added in reverse order to the beginning of the chain. So, when "L" is added first, it becomes the firstNode in the chain. Then, "A" is added and becomes the new firstNode, with its next reference pointing to "L". Similarly, "R" is added and becomes the new firstNode, with its next reference pointing to "A".

The problem in this scenario is likely due to the Linux user manually configuring a static IP address instead of using DHCP. The servers in the LAN are running Active Directory, DHCP, and DNS services. These services work together to provide IP address assignment, name resolution, and other network-related functionalities.

When the Linux user tries to ping your computer using its IP address, it is successful because IP-based communication does not rely on name resolution. However, when attempting to ping your computer using its computer name, the Linux user is unsuccessful. This suggests that the Linux user's computer is unable to resolve hostnames to IP addresses, which is crucial for accessing resources on the network and the internet. To resolve the issue, the Linux user should reconfigure their network interface card (NIC) to use DHCP for IP address assignment and DNS for name resolution. This will allow the Linux user's computer to obtain the necessary network settings from the DHCP server, including the correct DNS server address.

A semaphore is a synchronization tool used in computer science to control access to shared resources among concurrent processes.

One important aspect of a semaphore is the order in which processes are removed from the queue when they are waiting for the resource. This order can be either first-in-first-out (FIFO) or it can be non-deterministic, meaning that the processes are removed from the queue in an arbitrary order.

If a semaphore does not specify the order in which processes are removed from the queue, it is considered a non-deterministic semaphore. This means that the order in which processes acquire the resource is not predictable and may depend on factors such as scheduling, priority, or the timing of the processes' requests.

The average CPI of the program is 3.

To calculate the average CPI (Cycles Per Instruction) of the program, we need to consider the CPI of each instruction type and their respective frequencies.

Given information:

Total instructions: 30 billion

Execution time: 45 seconds

Clock frequency: 2 GHz (2 billion cycles per second)

Branch instructions: 25% of total instructions

CPI of branch instructions: 4

First, let's calculate the total number of cycles taken by the program:

Total cycles = Execution time × Clock frequency

Total cycles = 45 seconds × 2 billion cycles per second

Total cycles = 90 billion cycles

Next, let's calculate the number of cycles consumed by branch instructions:

Branch instruction count = 25% of total instructions

Branch instruction count = 0.25 × 30 billion

Branch instruction count = 7.5 billion

Cycles consumed by branch instructions = Branch instruction count × CPI of branch instructions

Cycles consumed by branch instructions = 7.5 billion × 4

Cycles consumed by branch instructions = 30 billion cycles

Now, let's calculate the number of cycles consumed by other instructions (non-branch instructions):

Cycles consumed by other instructions = Total cycles - Cycles consumed by branch instructions

Cycles consumed by other instructions = 90 billion cycles - 30 billion cycles

Cycles consumed by other instructions = 60 billion cycles

Finally, we can calculate the average CPI of the program:

Average CPI = (Cycles consumed by branch instructions + Cycles consumed by other instructions) / Total instructions

Average CPI = (30 billion cycles + 60 billion cycles) / 30 billion

Average CPI = 90 billion cycles / 30 billion

Average CPI = 3

Therefore, the average CPI of the program is 3.

In 64-bit architecture, allocating memory for 20 integers using the `malloc` function would require 88 bytes (20 * 4 + 8) of total memory.

In a 64-bit architecture, the size of a pointer is typically 8 bytes. Assuming you are allocating memory using the malloc function to store an array of integers, and the size of each integer is 4 bytes, you can calculate the total number of bytes allocated as follows:

Number of integers: 20

Size of each integer: 4 bytes

Size of the pointer: 8 bytes

Total bytes allocated = (Number of integers) * (Size of each integer) + (Size of the pointer)

                    = 20 * 4 + 8

                    = 80 + 8

                    = 88 bytes

Therefore, 88 bytes would be allocated in total for the statement `ptr (int*)malloc(20 * sizeof(int));` in a 64-bit architecture.

In object-oriented programming, method overloading is a technique that allows a class to have two or more methods with the same name but with different parameters. When a method is called, the compiler uses the method signature to determine which method to invoke based on the arguments passed to it.

Overloading methods with different parameter lists can be a useful technique for creating more flexible and versatile classes. By providing different parameter lists, a method can perform similar operations on different types of data, allowing for code reuse and simplification.

The process of overloading methods does not affect the behavior of the method itself, but rather provides additional ways to access the same functionality. The correct overload method to be called is determined at compile-time based on the type and number of parameters passed to the method.

Therefore, as long as the parameter lists are distinct, methods can be overloaded correctly without causing any ambiguity or confusion. This can lead to more efficient and maintainable code, making method overloading an important technique in object-oriented programming.
