Try making a character (string) variable and a logical variable . Try creating a variable with a "missing" value NA. You can cal
quester [9]

Answer:

The solution code is written in R script.

  1. #string variable
  2. character_str<- "Hello World"
  3. #logical variable
  4. logic <-  a > b
  5. #Missing value
  6. myVec <-c(1, 2, 3, NA)
  7. #Use class to check data type
  8. class(character_str)
  9. class(logic)
  10. class(myVec)

Explanation:

A string variable is a variable that hold a string (the letters enclosed within quotation marks) (Line 2)

A logical variable is a variable that hold a logical value (either True or False). The logical value is created by comparing two variables (Line 5).

In R, missing value is an unknown value which is represented by NA symbol (Line 8).  

We can use in-built method <em>class </em> to check for the variable type in R (Line 11-13). For example, the output of <em>class(character_str)</em> is "<em>character</em>"

Tpy6a [65]

Answer:

Most HTML tags are fixed

Explanation:

There are various kind of technology one can use for designing web application. A web designer should know HTML, CSS and other basic building block of web development.

HTML meaning hypertext markup language is used to define the basic structure of a web page . HTML has tags which are used to declare the contents on the web page. The tags includes anchor(<a>), paragraph tag(<p>),header tag(<h1>).

CSS which is known as Cascading style sheet describes the presentation of the web pages.

Other tags in HTML includes <img>, <link>, <ul>  etc and generally this tags are HTML tags which are fixed for a particular kind of job . For example you can't use an image tag <img>   to enclose video instead you use a video tag <video> tag. The header tag <h1> cannot be represented like a paragrapgh tag<p> on the web page. The both of them serve specific purpose and are fixed.

Write a program that prompts the user to enter the center and a point on the circle. The program should then output the circle’s
sergij07 [2.7K]

Here is the code in C++.

#include <bits/stdc++.h>

using namespace std;

// function to calculate distance between two points

double distance(int a,int b,int c,int d )

{

 // return the distance between center and point

  return sqrt(pow(c - a, 2) +

               pow(d - b, 2) * 1.0);

}

// driver function

int main()

{

// variables to store coordinates

int x1,y1,x2,y2;

cout<<"Please Enter the center(x y) of the circle: ";

//reading center

cin>>x1>>y1;

cout<<"\nPlease Enter a point(x1 y1) on the circle:";

//reading point

cin>>x2>>y2;

// calling distance() function with 4 parameters

double rad=distance(x1,y1,x2,y2);

// calculating Radius and print

cout<<"Radius of circle is: "<<rad<<endl;

// calculating Diameter and print

cout<<"Diameter of circle is: "<<2*rad<<endl;

// calculating Circumference and print

cout<<"Circumference of circle is: "<<2*3.14*rad<<endl;

// calculating Area and print

cout<<"Area of circle is: "<<3.14*rad*rad<<endl;

return 0;

}

Explanation:

First it will read coordinates of center and point on the circle.The distancebetween center and point on circle is Radius. Call distance() function withfour parameters which are coordinates of center and point. This will return the value of Radius. Diameter is 2 times of Radius.Diameter of a circle is 2*3.14*Radius. and Area of the circle is calculate as 3.14*Radius*Radius. After finding these value print them.

Output:

Please Enter the center(x y) of the circle: 0 0

Please Enter a point(x1 y1) on the circle: 3 4

Radius of circle is: 5

Diameter of circle is: 10

Circumference of circle is: 31.4

Area of circle is: 78.5

Write a program that takes in a line of text as input, and outputs that line of text in reverse. The program repeats, ending whe
Nana76 [90]

<u>Answer:</u>

<em>using System; </em>

<em>public class Program </em>

<em>{ </em>

<em> public static void Main() </em>

<em> { </em>

<em> String input ; </em>

<em> while(true) </em>

<em> { </em>

<em>  input = Console.ReadLine(); </em>

<em>  if(input.Equals(""quit"")) </em>

<em>  break; </em>

<em>  Reverse_String(input); </em>

<em> } </em>

<em> return; </em>

<em> } </em>

<em>static void Reverse_String(string input_text) </em>

<em>{ </em>

<em>    char[] text = input_text.ToCharArray(); </em>

<em>    Array.Reverse(text); </em>

<em>    Console.WriteLine(text); </em>

<em>} </em>

<u>Explanation:</u>

<em>In the above program a separate function is written to reverse the string.</em>

This method takes the string as an argument and place it in a array and then use the built-in function reverse and print the reversed string in the console.

<em>In the main(), the input is obtained from the console and it is passed to the reversestring(). </em>
