Long answer:1. The issue with the code is that the str array is not initialized. Thus, it could lead to undefined behavior. The fixed code is as follows:#include
#include
int main() {
char str[10] = "hello", new_str[10];
for (int i = 0; str[i] != '\0'; i++) {
new_str[i] = str[i];
}
printf("The new string = %s\n", new_str);
return 0;
}
2. The implementation of the longest_substring function is as follows:int longest_substring(char* str){
int len = strlen(str);
int cnt = 1, max_cnt = 1;
for(int i = 0; i < len; i++){
if(str[i] == str[i+1]){
cnt++;
if(cnt > max_cnt){
max_cnt = cnt;
}
}
else{
cnt = 1;
}
}
return max_cnt;
}The longest_substring function accepts a pointer to a string. The string is traversed using a for loop from 0 to length of the string. Finally, the max_cnt is returned. If there are no repeated characters in the string, the function returns 1.

The following piece of code is supposed to copy string str to new_str, but it doesn’t work correctly because the character array `str` is uninitialized.

As a result, the loop iterates indefinitely, causing a memory error. To fix the code, we should initialize the `str` array with a string and change the loop condition to terminate when the end of the string is reached.Here is the fixed code:```#include int main() {char str[10] = "hello", new_str[10];int i;for (i = 0; str[i] != '\0'; i++) {new_str[i] = str[i];printf("The new string = %s\n", new_str);new_str[i] = '\0';return 0;}```Explanation:

In the fixed code, we initialize the `str` array with the string "hello". We also declare the loop variable `i` outside the loop so that we can access it after the loop. Inside the loop, we copy each character of `str` to the corresponding index of `new_str`. After the loop, we add a null terminator to `new_str` to indicate the end of the string. Finally, we return 0 to indicate successful termination of the program.

a. Four fragments will be generated for the original datagram.

b. The values in the various fields in the IP datagram(s) generated that are related to fragmentation are as follows:

Maximum transmission unit (MTU) is the largest data chunk that can be transmitted over a network. In this case, an IP datagram of 1895 bytes is trying to be sent into a link that has an MTU of 576 bytes. This means that the datagram needs to be fragmented into smaller chunks before being sent across the network.

Each of these fragments will be a new IP datagram with a different IP header. The fragmentation process is carried out by the sender’s host IP software.

When fragmentation occurs, the original datagram is broken down into smaller pieces. Each piece is known as a fragment. The different fields affected by fragmentation are ID, fragment offset, MF (more fragments) flag, total length, and fragment length.

Design a timed state machine for a process with input event x and output events y and z, satisfying specified time delay constraints.

To design the timed state machine, we need to consider the following requirements:

1. Time Delays: The time delay between receiving input event x (x?) and issuing output events y (y!) and z (z!) should be between two and four units and three and five units, respectively.

2. Event Handling: While waiting to issue outputs, any additional input events should be ignored, meaning the process should not respond to new input events until the current outputs are issued.

To implement this timed process, we can create states to represent different stages of the process, and transitions between states should be triggered by the input event x. Each state will have a corresponding time delay before issuing the respective output events y and z.

The result of converting the Binary number (100011) to Decimal is 35.

The result of converting the Decimal number (64) to Binary is 1000000.

In binary representation, each digit represents a power of 2. Starting from the rightmost digit, the powers of 2 increase from 0 to n, where n is the number of digits.

For the first question, to convert the binary number (100011) to decimal, we calculate the value of each digit based on its position. Starting from the rightmost digit, we have 1, 0, 0, 0, 1, and 1. The rightmost digit represents 2^0 (which is 1), the next digit represents 2^1 (which is 2), and so on. We add up these values: 1 + 0 + 0 + 0 + 16 + 32 = 35. Therefore, the binary number (100011) is equal to the decimal number 35.

For the second question, to convert the decimal number (64) to binary, we find the largest power of 2 that is less than or equal to the given number. In this case, it is 2^6, which equals 64. We write a 1 in the corresponding position and subtract 64 from the original number. The remaining value is 0. Then, we move to the next smaller power of 2, which is 2^5 (32). Since the remaining value (0) is smaller than 32, we write a 0 in that position. We continue this process for the remaining powers of 2 until we reach 2^0. The resulting binary representation is 1000000.

The two main benefits of DNS are efficient resource management and user-friendly addressing.

DNS, which stands for Domain Name System, serves as a crucial component of the internet infrastructure. It plays a vital role in translating human-readable domain names into IP addresses, enabling efficient resource management and user-friendly addressing.

Firstly, DNS ensures efficient resource management by maintaining a distributed database of domain names and their corresponding IP addresses. When a user enters a domain name in their web browser, the DNS system quickly looks up the IP address associated with that domain name.

This process reduces the burden on individual servers and allows for load balancing across multiple servers. By distributing the load, DNS helps to optimize the performance and reliability of internet services, ensuring that websites and other online resources are accessible to users without overwhelming individual servers.

Secondly, DNS facilitates user-friendly addressing by providing meaningful domain names that are easy to remember and type. Imagine if you had to remember the IP address of every website you wanted to visit, such as 192.0.2.1 for example.

This would be highly impractical and error-prone. Instead, DNS allows us to use domain names like www.example.com, which are more intuitive and memorable. It simplifies the process of accessing resources on the internet, making it easier for users to navigate the online world.

In summary, the two main benefits of DNS are efficient resource management through load balancing and user-friendly addressing via domain names. DNS optimizes the distribution of internet traffic and enables users to access online resources using intuitive and memorable domain names.

The sliding window-based Go Back N ARQ protocol assumes that every time a packet is sent, the sender will keep a copy until the receiver sends a positive acknowledgment.

If a positive acknowledgment is not received by the sender for a specific amount of time, the sender retransmits the packet. The lost packet is the packet with sequence number 6, according to the given scenario. Following are the behaviors of both the nodes:

Node A is the sender, so it will retransmit all the lost packets (F6) and the packets that have not been acknowledged (F6 and F7).

Node B is the receiver, so it will receive the retransmitted packets and will acknowledge them if they are received correctly. If they are still not received correctly, node A will retransmit them. Additionally, node B should maintain a receive window of 7 frames (R0 through R6), allowing it to receive frames beyond R6 after it has received R6. However, it does not allow the frames to be passed on to the upper layer until R6 is received. If R6 is lost, node B will only accept frames with a sequence number less than or equal to 6, which means it will not acknowledge frames F7 and beyond.

Thus, node A will eventually time out and retransmit F6 and F7, which will allow node B to restart the receiver process and resend the acknowledgement R6. This behavior will continue until all the packets are successfully transmitted and acknowledged.

Write a snippet of Arduino code for making the stepper motor follow a triangular shape profile:

void setup() {

 // Initialize motor and set up other necessary configurations

}

void loop() {

 // Generate a triangular profile motion for the motor

}

To make the stepper motor follow a triangular shape profile, we need to utilize the setup() and loop() functions in the Arduino code.

In the setup() function, we would initialize the stepper motor and configure any necessary settings. This may involve defining the motor pins, setting the speed and direction, and enabling the required libraries or dependencies.

In the loop() function, we would generate the triangular profile motion for the motor. The triangular profile consists of three phases: acceleration, constant speed, and deceleration.

To achieve acceleration, we gradually increase the motor speed from an initial value to the desired maximum speed. This can be done by incrementing the step rate at regular intervals until the maximum speed is reached.

During the constant speed phase, the motor maintains a steady rotation at the maximum speed. We can accomplish this by keeping the step rate constant.

Lastly, in the deceleration phase, we gradually decrease the motor speed from the maximum value back to zero. Similar to acceleration, we decrement the step rate at regular intervals until it reaches zero.

By properly controlling the step rate and the timing of the acceleration and deceleration phases, we can achieve a triangular profile for the stepper motor motion.

| A000 0004  | Uninitialized   | q        |

| C000 0000  | Uninitialized   | Malloc 1 |

| C000 0004  | Uninitialized   | Malloc 2 |

| C000 0008  | Uninitialized   | Malloc 3 |

| C000 000C  | Uninitialized   | Malloc 4 |

| C000 0010  | Uninitialized   | Malloc 5 |

Explanation:

p and q are pointers to int and char respectively. They are uninitialized and don't have specific addresses assigned to them.

Malloc 1 to Malloc 5 represent the memory blocks allocated using malloc.

Each block has a size of sizeof(int) or sizeof(char) and is located at consecutive addresses starting from C000 0000.

However, the contents of these blocks are uninitialized in this table.

Android and iOS are two popular mobile operating systems with distinct differences in developing mobile applications.

Android and iOS have different programming languages and development environments. Android uses Java or Kotlin for app development and provides an open-source platform, allowing developers more flexibility and customization options. On the other hand, iOS uses Swift or Objective-C and operates within a closed ecosystem, providing a more controlled and consistent user experience.

One advantage of Android development is its wider market share, which offers a larger user base and potential for greater reach. Additionally, Android allows developers to create apps for various devices, including smartphones, tablets, and smart TVs. Moreover, Android offers more customization options and easier access to device features and system resources.

In contrast, iOS development is known for its focus on user experience and design. iOS apps generally have a polished and consistent interface, providing a seamless user experience across different devices. Apple's strict app review process ensures quality and security standards. Furthermore, iOS users tend to spend more on apps and in-app purchases, making it an attractive platform for monetization.

However, developing for iOS has its challenges. The closed ecosystem limits customization options, and the development tools and resources are exclusively available for Apple devices. Moreover, iOS development requires adherence to Apple's guidelines and approval process, which can be time-consuming.

In summary, the choice between Android and iOS development depends on factors such as target audience, project requirements, and development preferences. Android offers flexibility and a larger user base, while iOS provides a polished user experience and potential for monetization. Developers should consider these differences and choose the platform that aligns with their goals and target audience.
