To change pointers or references within an inheritance structure, use a dynamic_cast. The standard casting function for casting the pointer to various objects is static_cast. Use this function for simple type conversions.
An object that stores a memory address is known as a pointer in computer science and is used in many programming languages. Another value stored in computer memory or, in some situations, memory-mapped computer hardware may be the source of this. When a pointer accesses a location in memory, it is known as dereferencing the pointer to retrieve the value that is kept there. A page number in a book's index may be compared to a pointer to the relevant page; dereferencing such a pointer would include turning to the page indicated by the provided page number and reading the text there. Depending on the underlying computer architecture, a pointer variable's actual format and content may differ.

what is the flaw in using lines of code to compare the productivity of functional languages and that of imnperative languages?
Using lines of code as a measure of productivity is not a reliable way to compare the productivity of functional languages and imperative languages, or any other programming languages for that matter. This is because lines of code is not a consistent measure of the complexity or functionality of a program.
For example, a program written in a functional language might be able to accomplish a certain task using fewer lines of code than a program written in an imperative language, but that doesn't necessarily mean that the functional program is more productive or better in any way. Additionally, the way that lines of code are counted can vary depending on the individual or organization doing the counting, which can make it difficult to compare the productivity of different languages using this metric. It is generally better to use more robust measures of productivity, such as the time it takes to develop and maintain a program, or the number of bugs and other issues that are found in the code.

refer to the exhibit. an administrator is trying to configure the switch but receives the error message that is displayed in the exhibit. what is the problem?
An administrator is trying to configure the switch but receives an error message. The administrator is attempting to configure the switch without first enabling privileged EXEC mode, which is the problem.
What is EXEC mode?One advantage of turning on privileged EXEC mode is that it gives the administrator the most access and control possible over the switch. The administrator can customize the switch to their particular needs because they have the highest level of access.
This entails configuring particular access control lists and making adjustments to the switch's configuration files. The administrator does not have access to all the commands and options that are available in privileged EXEC mode while operating in user EXEC mode.
Therefore, the issue is that the administrator is trying to configure the switch without first enabling privileged EXEC mode.

a coin is tossed 10 times and the output written as a string. what is the expected number of hh? note that in hhh, number of hh
The result is written as a string after 10 coin tosses. The predicted amount of hh is nine.
The recursive relation I came up with is
E(10)=1/2E(9)+1/4E(8)+1/4(E(9)+1)
The last toss has a probability of 1/2, so we only need to look at the number of consecutive heads in the first nine tosses. However, if the last toss is H, it matters what the second last toss was; if it was TH, then the number of consecutive heads was the same as in the first eight tosses; however, if it was HH, then the number of consecutive heads was one more than the number of heads in the first nine tosses.
The solution given states the following recursive relation
E(10)=1/2E(9)+1/4E(9)+1/4(E(9)+1)
In programming, a string is a form of data that is used to represent text rather than integers. Letters, numbers, symbols, and even spaces can all be found in a string, which is a collection of characters. For it to be recognized as a string, it needs to be encapsulated in quotation marks.
For instance, "liquid" and the question "What is liquid? Both of these strings are in a template language. Even the letter combination "98OkJJ$%janUJ£" is regarded as a string.

Any binary integer may be shifted to the left or the right using binary shifting. Then a 0 is used in place of the void. By demonstrating a binary shift to the left, we can observe this in effect.
A binary shift shifts all the digits in the binary number along to the right and fills the spaces following the shift with 0 to divide a number by two, for example. Bit shifting is a process that moves all the bits in a binary value a certain number of positions to the left or right. When the operand is being utilized as a collection of bits rather than as a whole, bit shifting is employed. The leftmost bit is eliminated as a result of a binary left shift. The remaining pieces all shift one position to the left. The rightmost vacant space will be filled with a 0.

the global system for mobile communications (gsm) utilizes what technology to create timeslots on a channel?
Time division multiple access (TDMA) technology is used by the global system for mobile communications (gsm) to establish timeslots on a channel.
The channel access technique known as time-division multiple access (TDMA) is utilized for shared-medium networks. It makes it possible for several users to share a single frequency channel by splitting the signal up into several time slots. Each user utilizes a different time slot and transmits one after the other quickly. This allows a lot of stations to use the same transmission medium by using only a portion of the channel's capacity (such as a radio frequency channel). The TDMA variant known as dynamic TDMA dynamically reserves a variable number of time slots in each frame to variable bit-rate data streams based on the traffic requirements of each data stream.
