Answer:
Explanation:
The following function is written in Java and takes in three parameters the array, its size, and the chosenNumber that will be counted. The function then creates an instance variable called Counter and loops through the given array looking for the chosenNumber. Every time that the number is found in the array it adds 1 to the counter. Once the loop is done it returns the total value of the counter variable.
public static int counter(int[] numbers, int Size, int chosenNumber) {
int counter = 0;
for (int x = 0; x < Size; x++) {
if(numbers[x] == chosenNumber) {
counter++;
}
}
return counter;
}

hope it helpsWhat are stored procedures? What kind of attack do stored procedures protect from? Identify two reasons why stored procedures are a good mitigation against the specific attack. g
Answer:
Stored procedures or procedures are subroutines or subprograms in SQL written by the user to accomplish a certain task. it helps to mitigate SQL injection by using markers as placeholders for data input and it streams the query statement and data separately in the database.
Explanation:
The stored procedure used in SQL is a user-defined function. Unlike built-in functions like pi(), they must be called to use them.
SQL injection in query statements is written by hackers to bypass conditions, especially when trying to gain access to other user accounts. Stored procedures use markers or placeholders to prevent this.

What are the advantages and disadvantages of using steganography versus symmetric or asymmetric encryption
Explanation:
Steganography is a technique used in securing or hiding sensitive information by encrypting the information in a non-hidden file like a JPEG format. A major advantage of this method is that it reduces the risk of attack or break-in since the data is enclosed in a non-secure file; thereby reducing threats of any hack. One main disadvantage of this method is that the hidden message may become difficult to recover if the source file (non-secure file) used, is edited or deleted.
In symmetric or asymmetric encryption they both employ cryptographic encryption method. While symmetric encryption uses one key to encrypt and decrypt data, asymmetric encryption uses two keys (one for encryption, the other for decryption) of the data. A major advantage of using these methods is that they provide more security. Although while symmetric encryption is faster, asymmetric encryption is slower (eg using separate keys to gain access), a disadvantage.
Advantage:
Because the content is contained throughout a non-secure file, the above strategy decreases the chance of an assault on classified info.Disadvantage:
This approach has the disadvantage that concealed information might be able to retrieve if somehow the documents have been changed or deleted as of a non-secure file.Once again to encrypt as well as decode information, symmetric encryption employs a unique key, but asymmetric encryption utilizes two different keys, something for encryption as well as someone else for decryption.
Advantage:
One such approach is superior to steganography throughout the level of protection.Disadvantage:
Because distinct keys have been needed to get access, such techniques of asymmetric encryption are considerably slower.Thus the approach above is correct.

Byte needs to store text made up of the characters A with frequency 6, B with frequency 2, C with frequency 3, D with frequency 2, and E with frequency 8. Professor Byte suggests using the variable length codes:
Character Code
A 1
B 00
C 01
D 10
E 0
The professor argues that these codes store the text in less space than that used by an optimal Huffman code. Is the professor correct?
Answer:
This is not true
Explanation:
The optimal Huffman code is used to encrypt and compress text files. It uses fixed-length code or variable-length code for encryption and compression of data.
The professor's character code is similar to Huffman's variable-length coding which uses variable length od binary digits to represent the word strings. The file size of the text file above is;
= 6 x 1 + 2 x 2 + 3 x 2 + 2 x 2 + 8 x 1 = 28 bits
This would be the same for both cases.
The encrypt would be the problem as the encoded and decoding of the characters B and E may cause an error.

Only one programming language is required.
Websites may have more professional construction.
Knowledge of HTML is not required.
Website templates are not necessary.
Answer:
The answer to this question is given below in the explanation section.
Explanation:
The correct answer among the given options to this question is:
Knowledge of HTML is not required.
Because when you are constructing a website using WYSIWYG (“what you see is what you get”) editor, then you don't need the knowledge of HTML. Because, when you use WYSIWYG editor to insert button, table, images, text, paragraph, etc. It will automatically insert HTML code behind the page. For example, you can insert a form and a submit button using drag and drop with the help of WYSIWYG (“what you see is what you get”) editor, for this purpose, you don't need exact knowledge of HTML. WYSIWYG (“what you see is what you get”) automatically inserts the HTML for the form and button on a website page.
While other options are not correct because:
Using the WYSIWYG (“what you see is what you get”) editor, you can use different programming languages in your website, such as VB.net, Asp.Net, C#, Javascript, Bootstrap, etc. It is not necessarily that you may have more professional construction and in WYSIWYG (“what you see is what you get”) website templates are mostly used and modified using WYSIWYG editor.

How many permutations for a 7 characters in length string, which contains all following letters R, X, S, Y, T, Z, U, has either the string 'RXS' or string 'ZU' in the 7 characters string?
Answer:
Following are the solution to this question:
Explanation:
In the following forms, RXS can appear:
[tex]R X S \_ \_ \_ \_[/tex] it may look like that really, [tex]4 \times 3 \times 2 \times 1[/tex] forms = 24 may construct the remainder of its letters.
[tex]\_ R X S \_ \_ \_[/tex] it may look like that really, [tex]4 \times 3 \times 2 \times 1[/tex] forms = 24 may construct the remainder of its letters.
[tex]\_ \_ R X S \_ \_[/tex] it may look like that really, [tex]4 \times 3 \times 2 \times 1[/tex] forms = 24 may construct the remainder of its letters.
[tex]\_ \_ \_ R X S \_[/tex] it may look like that really, [tex]4 \times 3 \times 2 \times 1[/tex] forms = 24 may construct the remainder of its letters.
[tex]\_ \_ \_ \_ R X S[/tex] it may look like that really, [tex]4 \times 3 \times 2 \times 1[/tex] forms = 24 may construct the remainder of its letters.
And we'll have a total of [tex]24 \times 5 = 120[/tex] permutations with both the string RXS.
In the following forms, UZ can appear:
[tex]U Z \_ \_ \_ \_\ _[/tex] They can organize your remaining 5 characters through 5 categories! Procedures [tex]= 5 \times 4 \times 3 \times 2 \times 1 = 120[/tex]
[tex]\_ UZ \_ \_ \_ \_[/tex] They can organize your remaining 5 characters through 5 categories! Procedures [tex]= 5 \times 4 \times 3 \times 2 \times 1 = 120[/tex]
[tex]\_ \_ U Z \_ \_ \_[/tex]They can organize your remaining 5 characters through 5 categories! Procedures [tex]= 5 \times 4 \times 3 \times 2 \times 1 = 120[/tex]
[tex]\_ \_ \_ U Z \_ \_[/tex]They can organize your remaining 5 characters through 5 categories! Procedures [tex]= 5 \times 4 \times 3 \times 2 \times 1 = 120[/tex]
[tex]\_ \_ \_ \_ U Z \_[/tex] They can organize your remaining 5 characters through 5 categories! Procedures [tex]= 5 \times 4 \times 3 \times 2 \times 1 = 120[/tex]
[tex]\_ \_ \_ \_ \_ U Z[/tex] They can organize your remaining 5 characters through 5 categories! Procedures [tex]= 5 \times 4 \times 3 \times 2 \times 1 = 120[/tex]
There may be [tex]120 \times 6 = 720[/tex] ways of complete permutations.

Write a function that accepts a pointer to a C-string as an argument and returns the number of words contained in the string. For instance, if the string argument is 'Four score and seven years ago,' the function should return the number 6. Demonstrate the function in a program that asks the user to input a string and then passes it to the function. The number of words in the string should be displayed on the screen.
Answer:
To preserve the original format of the answer, I've added it as an attachment
Explanation:
This line defines the function
int countWords(const char ptr){
This line initializes number of words to 0
int words = 0;
The following iteration is repeated until the last character in the argument is reached
while(*(ptr) != \0){
This checks if current character is blank
if(*ptr== ){
If yes, then it increments number of words by 1
words++;
}
This moves the pointer to the next character
ptr++;
}
This returns the number of words in the argument
return words+1;
}
The main begins here
int main() {
This declares user input as a character of 200 length
char userinput[200];
This prompts user for input
cout << Enter a string: (200 max): ;
This gets user input
cin.getline(userinput, 200);
This passes the c-string to the function and also prints the number of words
cout << There are << countWords(userinput)<< words;
