Chapter 7, Problem 5PE

Explanation of Solution

Program:

File name: “CountWords.java

//Import necessary header files

import java.util.*;

//Define a class named CountWords

public class CountWords

{

    //Define main method

    public static void main(String[] args)

    {

        //Create an object for the Scanner class

        Scanner in = new Scanner(System.in);

        //Declare the variables

        String str;

        char ch;

        int x;

        int count = 0;

        int length;

        //Declare a Boolean variable and initialize the value

        boolean previousCharWasPunc = false;

        //Prompt the user to enter a String

        System.out.print("Enter a string >> ");

        str = in.nextLine();

        //Read the length of the String

        length = str.length();

        //For loop is executed until x exceeds the string length

        for(x = 0; x < length; x++)

        {

            ch = str.charAt(x);

/* If the words are separated by any combination of spaces,

            periods, commas, semicolons, question marks,

            exclamation points, or dashes*/

            if(ch == ' ' || ch == '...

TECNOLOGIE DEL WEB 2023/2023 (VER 1.1) Prof. Alfonso Pierantonio 1. Project Requirements The project consists in designing and implementing a Web application according to the methodology and the technologies illustrated and developed during the course. This document describe cross-cutting requirements the application must satisfy. The application must be realized with a combination of the following technologies: PHP MySQL HTML/CSS JavaScript, jQuery, etc templating The requirements are 2. Project size The application must have at least 18 SQL tables The number of SQL tables refers to the overall number of tables (including relation normalizations). 3. Methodology The application must be realized by adopting separation of logics, session management, and generic user management (authentication/permissions). Missing one of the above might correspond to a non sufficient score for the project. More in details: 3.1 Separation of Logics The separation of logics has to be realizse by using…
Write a C program to calculate the function sin(x) or cos(x) using a Taylor series expansion around the point 0. In other words, you will program the sine or cosine function yourself, without using any existing solution. You can enter the angles in degrees or radians. The program must work for any input, e.g. -4500° or +8649°. The function will have two arguments: float sinus(float radians, float epsilon); For your own implementation, use one of the following relations (you only need to program either sine or cosine, you don't need both): Tip 1:  Of course, you cannot calculate the sum of an infinite series indefinitely. You can see (if not, look in the program) that the terms keep getting smaller, so there will definitely be a situation where adding another term will not change the result in any way (see problem 1.3 – machine epsilon). However, you can end the calculation even earlier – when the result changes by less than epsilon (a pre-specified, sufficiently small number, e.g.…
