explain the structure of c program with example

Answers

Answer:

A C program typically consists of a number of components, including preprocessor directives, function prototypes, global variables, functions, and a main function.

Explanation:

Here's an explanation of each component, followed by an example C program that demonstrates their usage:

Preprocessor Directives: Preprocessor directives are instructions to the C preprocessor, which processes the source code before compilation. They usually start with a '#' symbol. Some common directives are #include for including header files and #define for defining constants.

Function Prototypes: Function prototypes provide a declaration of functions that will be used in the program. They specify the function's name, return type, and the types of its parameters.

Global Variables: Global variables are variables that can be accessed by any function in the program. They are usually defined outside of any function.

Functions: Functions are blocks of code that can be called by name to perform specific tasks. They can accept input parameters and return a value. Functions are generally declared before the main function.

Main Function: The main function is the entry point of the program. It's where the execution starts and ends. It has a return type of int and typically takes command-line arguments via two parameters: argc (argument count) and argv (argument vector).

Here's an example C program that demonstrates the structure:

// Preprocessor directives

#include <stdio.h>

// Function prototypes

void print_hello_world(void);

// Global variable

int global_var = 10;

// Functions

void print_hello_world(void) {

   printf("Hello, World!\n");

}

// Main function

int main(int argc, char *argv[]) {

   // Local variable

   int local_var = 20;

   printf("Global variable value: %d\n", global_var);

   printf("Local variable value: %d\n", local_var);

   print_hello_world();

   return 0;

}

This simple C program demonstrates the use of preprocessor directives, a function prototype, a global variable, a function, and the main function. When run, it prints the values of a global and a local variable, followed by "Hello, World!".

One way to project the 2D data points onto a 1D space while preserving linear separability is through the use of a linear discriminant analysis (LDA) technique. LDA finds the linear combination of the original features that maximizes the separation between the different classes.

What is the mathematics  in SVM algorithm?

The mathematics behind LDA involve finding the eigenvectors of the within-class scatter matrix and the between-class scatter matrix and selecting the eigenvector that corresponds to the largest eigenvalue. The full algorithm for LDA can be outlined as follows:

Compute the mean vectors for each class

Compute the within-class scatter matrix (SW) and the between-class scatter matrix (SB)Compute the eigenvectors and eigenvalues of the matrix (SW⁻¹SB)Select the eigenvector that corresponds to the largest eigenvalue as the linear discriminantProject the original data onto the new 1D space using the linear discriminant

Regarding the SVM algorithm, it can be applied directly to the original 2D data without the need for dimension reduction. The mathematics behind SVM involve finding the hyperplane that maximizes the margin, or the distance between the closest data points of each class, while also ensuring that the data points are correctly classified.

The full algorithm for SVM can be outlined as follows:

Select a kernel function (e.g. linear, polynomial, radial basis function)Train the model by solving the optimization problem that maximizes the marginUse the trained model to classify new data points by finding the hyperplane that separates the different classesIt is important to note that, in case of non-linearly separable data, SVM algorithm uses the kernel trick to map the original data into a higher dimensional space, where the data is linearly separable.

q = "this computer program produces the correct output when run with the test data my teacher gave me."

c = "This computer program is correct."

Meaning, p ⇒ q (p results in q), then we can conclude that,

(30 points) Medium Access Control (Questions) Q1: (25 points) Explain in your own words the evolution from Aloha to CSMA/CD. Explain how they differ and how each newer protocol improves the previous one: describe each one how it works and provide its perforamance, then contrast it with the protocol it improves. Q2: (5 points) What is the purpose of collision detection in CSMA/CD

Answers

Answer: : Provided below in the explanation section

Explanation:

ALOHA ,CSMA and CSMA/CD are Random access protocol which goes under Multiple entrance protocol.

IN arbitrary or random access protocol no station is relegated any predominance. In wcich each station have equivalent rights over the medium in which they need to transmit information.

Salaam is an irregular access protocol, a framework for getting to the mutual correspondence Networks channel. It was created during the 1970s by Norman Abramson and his partners at the University of Hawaii.

In Aloha, different stations can transmit information simultaneously and can henceforth prompt crash and information being jumbled.

From research we can say that there are two unique renditions of ALOHA:

Slotted ALOHA Pure ALOHA

In the Slotted ALOHA, the hour of getting to the mutual channel is partitioned into discrete intervals called slots.

While for the Pure ALOHA, the stations transmit outlines at whatever point they have information to send.

Opened ALOHA was created to improve the productivity of unadulterated ALOHA as odds of impact in unadulterated ALOHA is exceptionally high.

Still there are a few weaknesses in Aloha i.e, In ALOHA, hubs transmit parcels when they are accessible, without detecting the remote bearer. Therefore, parcels may crash at a beneficiary on the off chance that they are transmitted at the same time.

TO maintain a strategic distance from the above issue there came another protocal CSMA which is called as Carrier Sense Multiple Access (it is an improved type of irregular access convention that previously existed). The name its self proposes that in this the hubs first sense the remote medium before transmitting their information bundles. In the event that the medium is detected occupied, at that point transmissions are postponed else the information bundles are transmited.

After which CSMA/CD (Carrier sense different access with crash location) and CSMA/CA (Carrier sense numerous entrance with impact shirking) are acquainted with further more increment the productivity in impact recognition and impact evasion individually. When a collosion is dectected by CSMA/CD, it retransmits the impacted casings again by halting the transmision when crash recognized. Where as CSMA/CA thoroughly stays away from crash it helps in maintaining a strategic distance from impacts with the assistance of Interframe space(), Contention Window and Acknowledgment

For Q2:-

The prime reason for development from ALOHA to CSMA/CD is that the crash between the data packets.

That is to say CD in CSMA/CD i.e, Collision Detection reason for existing is that, at whatever point a crash occurs in a medium between the parcels it will help in halting the transmission and retransmit the impacted casing again and afterward proceeds with the halted transmission.

An engineer working as a computer programmer played a minor role in developing a computer system for a state department of health. The system stored medical information on individuals identified by name. Through no fault of the engineer, few controls had been placed on the system to limit easy access to it by unauthorized people. Upon learning of this, the engineer first informed his supervisor and then higher management, all of whom refused to do anything about the situation because of the anticipated expense required to correct it. In violation of the rules for using the system, the programmer very easily obtained a copy of his own medical records.
