Taking a suitable example in c language explain the of call by value and call by reference concepts.
Degger [83]

Answer: The difference between call by value and call by reference is that in call by value the actual parameters are passed into the function as arguments whereas in call by reference the address of the variables are sent as parameters.

Explanation:

Some examples are:

call by value

#include <stdio.h>  

void swap(int, int);

int main()

{  int a = 10, b= 20;

 swap(a, b);

 printf("a: %d, b: %d\n", a, b);

}  

void swap(int c, int d)

{

 int t;

 t = c; c = d; d = t;

}  

OUTPUT

a: 10, b: 20

The value of a and b remain unchanged as the values are local

//call by reference

#include <stdio.h>

 void swap(int*, int*);

 int main()

{

 int a = 10, b = 20;

 swap(&a, &b);   //passing the address

 printf("a: %d, b: %d\n", a, b);

}

void swap(int *c, int *d)

{

 int t;

 t = *c; *c = *d; *d = t;

}

OUTPUT

a: 20, b: 10

due to dereferencing by the pointer the value  can be changed which is call by reference

Paladinen [302]

Answer:

Explanation:

The following function/program is written in Java. It asks the user for a sentence as an input and then splits that sentence into an array of words. Then it creates an arrayList for all of the unique words, comparing each word in the sentence with all of those in the ArrayList. If a word is found in the ArrayList it cancels the loop and moves on the next word in the sentence. Finally, it counts all of the unique words in the ArrayList and prints that total to the screen.

public static void uniqueWords() {

       Scanner in = new Scanner(System.in);

       System.out.println("Enter a sentence:");

       String sentence = in.nextLine();

       String words[] = sentence.split(" ");

       ArrayList<String> uniqueWords = new ArrayList<>();

       for (int x = 0; x < words.length; x++) {

           boolean exists = false;

           for (int i = 0; i < uniqueWords.size(); i++) {

               if (words[x].equals(uniqueWords.get(i))) {

                   exists = true;

                   break;

               }

           }

           if (exists == false) {

               uniqueWords.add(words[x]);

           }

       }

       System.out.println(uniqueWords.size());

   }

PLS HELP: Identify the correct CSS syntax to link an external style sheet??
kupik [55]

Answer:

See Explanation

Explanation:

This question required options. Since there are none, I'll answer on a general terms.

To link to an external style sheet in CSS, use the following syntax:

<link rel = "stylesheet" type = "text/css" href = "link to css file">

As seen above, the link tag is used to achieve this tax.

The rel attributes shows the relationship between the css file and the html file.

In this case, the css file is a stylesheet; hence, rel = "stylesheet"

Next, is the type attribute which shows the content of the file to be linked. In other words, the file type

Lastly, the link to the css file.

Take for instance, the file name is example.css and it is in the same directory as the current document, the following will be used.

href = "example.css"

<em>However, if example.css is in a different directory, the link to the file directory will be stated.</em>

<em></em>

Conclusively, one syntax to use for a file named example.css is:

<em><link rel = "stylesheet" type = "text/css" href = "exampl.css"></em>
