Answer:

C language does not support strings as a data type. A string is actually one-dimensional array of characters in C language. These are often used to create meaningful and readable programs.

Find the equation of a line which has 10 points the following two coordinates: (4, 0) and (3, 4)

alex41 [277]

Answer:

The equation of the line is y = -4·x + 16

10 points on the line include;

(0, 16), (1, 12), (2, 8), (3, 4), (4, 0), (5, -4), (6, -8), (7, 12), (8, -16), (9, -20), and (10, -24)

Explanation:

The given points through which the line passes are;

(4, 0) and (3, 4)

The slope, 'm', of the line is given as follows;

$Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Therefore, the slope of the line is (4 - 0)/(3 - 4) = -4

In point and slope form we can get;

$\dfrac{y-0}{x-4} = -4$

The equation of the line in point and slope form is therefore;

y = -4·(x - 4) = -4·x + 16

The equation of the line in slope and intercept form is

y = -4·x + 16

10 points on the line are obtained using the equation of the line and the desired x-values input into cells on MS Excel and presented here as follows;

(0, 16), (1, 12), (2, 8), (3, 4), (4, 0), (5, -4), (6, -8), (7, 12), (8, -16), (9, -20), and (10, -24)

1. Write a function that will ask the user to enter a value in dollars. The function should calculate and display the equivalent

julia-pushkina [17]

Answer:

import java.util.Scanner;

public class Main

{

public static void main(String[] args) {

valueInDollars();

}

public static void valueInDollars() {

double currentMoney, quarters, dimes, nickels, pennies;

Scanner input = new Scanner(System.in);

System.out.print("Enter a value in dollars: ");

currentMoney = input.nextDouble();

currentMoney *= 100;

quarters = (int)currentMoney / 25;

currentMoney = currentMoney % 25;

dimes = (int)currentMoney / 10;

currentMoney = currentMoney % 10;

nickels = (int)currentMoney / 5;

currentMoney = currentMoney % 5;

pennies = currentMoney;

System.out.print("Quarters: " + quarters + "\n" + "Dimes: " + dimes + "\n" + "Nickels: " + nickels + "\n" + "Pennies: " + pennies);

}

Explanation:

Inside the function:

- Declare the variables

- Ask the user for a value in dollars

- Multiply that value by 100

- Find the amount of quarters, dimes, nickels, and pennies

- Print the values

Inside the main:

- Call the function

Write C++ code to open a document with the name Hello.txt, place the message "Hello, World!" in the document, and exit the docum

gavmur [86]

Answer:

#include<iostream>

#include<fstream>

using namespace std;

int main()

{

ofstream out;

out.open("Hello.txt");

out << "Hello, World!"<< endl;

out.close();

ifstream in;

in.open("Hello.txt");

while(in.good()){

string line;

in >> line;

cout << line << endl;

}

in.close();

return 0;

}

Explanation:

Step 1:

Add all your preprocessor files directive, #include is known as the preprocessor is used to load files needed to run the code.

#include<iostream>: it provides basic input and output services for C++ programs.

#include<fstream>:used to open a file for writing and reading

using namespace std; means you'll be using namespace std means that you are going to use classes or functions (if any) from "std" namespace

Step 2:

ofstream out; his is used to create files and write data to the file

out.open("Hello.txt"); a new file "HELLO.txt" has been created

out << "Hello, World!"<< endl; "Hello World!" has now been writen to the file

out.close(); The file is now closed

This second step opens a new file and writes hello world to the file then closes it.

Step 3:

ifstream in; ifstream in c++ is a stream class which stands for input file stream a is used for reading data from file.

in.open("Hello.txt"); Reopens the file without recreating it. This is a very important step because if not done properly, you might discard the file you previously created and recreate it.

while(in.good()){

in.good() is true if the previous read operation succeeded without EOF being encountered

string line; It declares a string variable line

in >> line; reads the data into the line variable

cout << line << endl; Prints out the line

reopens the file and read the message into a string variable "line". prints out line then exits out of the file.
