g Write a method that accepts a String object as an argument and displays its contents backward. For instance, if the string argument is "gravity" the method should display -"ytivarg". Demonstrate the method in a program that asks the user to input a string and then passes it to the method.

Answers

Answer:

The program written in C++ is as follows; (See Explanation Section for explanation)

#include <iostream>

using namespace std;

void revstring(string word)

{

   string  stringreverse = "";

   for(int i = word.length() - 1; i>=0; i--)

 {

     stringreverse+=word[i];

 }

 cout<<stringreverse;

}

int main()

{

 string user_input;

 cout << "Enter a string:  ";

 getline (std::cin, user_input);

 getstring(user_input);

 return 0;

}

Explanation:

The method starts here

void getstring(string word)

{

This line initializes a string variable to an empty string

   string  stringreverse = "";

This iteration iterates through the character of the user input from the last to the first

   for(int i = word.length() - 1; i>=0; i--)   {

     stringreverse+=word[i];

 }

This line prints the reversed string

 cout<<stringreverse;

}

The main method starts here

int main()

{

This line declares a string variable for user input

 string user_input;

This line prompts the user for input

 cout << "Enter a string:  ";

This line gets user input

 getline (std::cin, user_input);

This line passes the input string to the method

 revstring(user_input);

 return 0;

}

Answers

Answer:

The programming language is not stated; However, the program written in C++ is as follows: (See Attachment)

#include<iostream>

using namespace std;

string capt(string result)

{

result[0] = toupper(result[0]);

for(int i =0;i<result.length();i++){

 if(result[i]=='.' || result[i]=='?' ||result[i]=='!')  {

 if(result[i+1]==' ') {

  result[i+2] = toupper(result[i+2]);

 }

 if(result[i+2]==' ')  {

  result[i+3] = toupper(result[i+3]);

 }

 } }

return result;

}

int main(){

string sentence;

getline(cin,sentence);

cout<<capt(sentence);

return 0;

}

Explanation:

The method to capitalize first letters of string starts here

string capt(string result){

This line capitalizes the first letter of the sentence

result[0] = toupper(result[0]);

This iteration iterates through each letter of the input sentence

for(int i =0;i<result.length();i++){

This checks if the current character is a period (.), a question mark (?) or an exclamation mark (!)

if(result[i]=='.' || result[i]=='?' ||result[i]=='!')  {

 if(result[i+1]==' '){  ->This condition checks if the sentence is single spaced

  result[i+2] = toupper(result[i+2]);

-> If both conditions are satisfied, a sentence is detected and the first letter is capitalized

 }

 if(result[i+2]==' '){ ->This condition checks if the sentence is double spaced

  result[i+3] = toupper(result[i+3]);

-> If both conditions are satisfied, a sentence is detected and the first letter is capitalized

 }

}

}  The iteration ends here

return result;  ->The new string is returned here.

}

The main method starts here

int main(){

This declares a string variable named sentence

string sentence;

This gets the user input

getline(cin,sentence);

This passes the input string to the method defined above

cout<<capt(sentence);

return 0;

}

A proper divisor of a positive integer $n$ is a positive integer $d < n$ such that $d$ divides $n$ evenly, or alternatively if $n$ is a multiple of $d$. For example, the proper divisors of 12 are 1, 2, 3, 4, and 6, but not 12. A positive integer $n$ is called double-perfect if the sum of its proper divisors equals $2n$. For example, 120 is double-perfect (and in fact is the smallest double-perfect number) because its proper divisors are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, and 60, and their sum is 240, which is twice 120. There is only one other 3-digit double-perfect number. Write a Python program to find it, and enter the number as your answer below.

Answers

Answer:

The program written in Python is as follows:

See Explanation section for line by line explanation

for n in range(100,1000):

     isum = 0

     for d in range(1,n):

           if n%d == 0:

                 isum += d

     if isum == n * 2:

           print(n)

Explanation:

The program only considers 3 digit numbers. hence the range of n is from 100 to 999

for n in range(100,1000):

This line initializes sum to 0

     isum = 0

This line is an iteration that stands as the divisor

     for d in range(1,n):

This line checks if a number, d can evenly divide n

           if n%d == 0:

If yes, the sum is updated

                 isum += d

This line checks if the current number n is a double-perfect number

     if isum == n * 2:

If yes, n is printed

           print(n)

When the program is run, the displayed output is 120 and 672

Which of the following statements is true of an encrypted file? * The file can be read only by a user with the decryption key The file can be read by the creator and system administrator The file can not be opened again The file can be opened but not read again

Answers

Answer:

The file can be read only by a user with the decryption key

Explanation:

The way encryption works is it scrambles the data in a file following the rules of the encryption algorithm using a certain key to tell it how to scramble everything.

Without the key, the computer doesn't know how to decrypt it.

This is true no matter who has access to the file, be it a system administrator, a hacker, or even a legitimate user who has somehow lost access to the key

Strictly speaking, encryption can be broken, but, especially with modern encryption, that's a matter of centuries, and isn't really feasible

The statement that is true of an encrypted file is that The file can be read only by a user with the decryption key.

What is decryption key?

A decryption key is known to be a key that is given to Customers by a specific Distributor.

Hash function have less collision than a internet checksum because of computational infeasibility.

Explanation:

A collision means there is more then one way to produce the same sum. It is nearly difficult to developed two messages with same hash however, in checksum, it is more easier to develop or modify two messages to have same sum, thereby enabling attackers to have access to the message or the information arising to less message integrity.

Discuss the scaled index addressing mode and comments on the following instructions?

a) MOV BX, [CX+5*AX]
b) MOV [DX5*DI+30H], CX

Answers

Memory will also be accessible in Scaled index addressing mode using a 32-bit base & indexing register.The instruction's first parameter will be the base register, and the instruction's second parameter will be the index register. The index register is multiplied by a scaling factor before the program is fetched.

For option a:

The baseline register is [tex]\bold{BX}[/tex], while the index register is [tex]\bold{CX+5*AX}[/tex].

The multiplier for Accumulator [tex]\bold{AX }[/tex] will be 5.[tex]\bold{CX }[/tex] will be multiplied with this value.[tex]\bold{CX+5*AX}[/tex] will contain a memory address.The value at position [tex]\bold{CX+5*AX}[/tex] is accessed by [tex]\bold{[{CX+5*AX} ]}[/tex].The value retrieved from the address [tex][\bold{CX+5*AX}][/tex] is moved into Base register BX by the MOV instruction.

For option b:

Its index register is [tex]\bold{CX }[/tex], whereas the base register is [tex]\bold{DX5*DI+30H}[/tex].

[tex]\bold{CX}[/tex] has a number, that is copied to a computed place below.After multiplying [tex]\bold{DI}[/tex] by [tex]\bold{5, DX}[/tex] will be multiplied by this [tex]\bold{5*DI}[/tex].To the aforementioned multiplied value,[tex]\bold{ 30H}[/tex] will be added.[tex]\bold{[DX5*DI+30H]}[/tex] is a value located at location [tex]\bold{DX5*DI+30H}[/tex]. [tex]\bold{DX5*DI+30H }[/tex] is a memory address number.As a result, the value of [tex]\bold{CX}[/tex] will be copied to the [tex]\bold{ [DX5*DI+30H] }[/tex]location.
