4.2 Lesson Practice​

Answer:

def main():

   is_true = True

   while is_true == False:

       try:

           num1 = int(input("Enter first number: ")

           num2 = int(input("Enter second number: ")

           num3 = int(input("Enter third number: ")

       except ValueError:

           print("Input must be an integer number")

       is_true = bool(input("do you want to end loop? True/False: "))

main()

Explanation:

The python main function above continuously creates three integer numbers in a while loop statement until a false input is received from the user.

Answer:

Explanation:

The following code is written in the Java programming language and actually takes in three parameters, the first is the list with all of the int values. The second parameter is the starting point where the adding needs to start. Lastly is the int finalSum which is the variable where the values are all going to be added in order to calculate a final int value. Once the recursive function finishes going through the list it exits the function and prints out the finalSum value.

   public static void sum_Values(ArrayList<Integer> myList, int startingPoint, int finalSum) {

           if (myList.size() == startingPoint) {

               System.out.println(finalSum);

               return;

           } else {

               finalSum += myList.get(startingPoint);

               sum_Values(myList, startingPoint+1, finalSum);

           }

   }

Answer:

A display device is the most common form of output device it presents output visually on a computer screen.the output appears temporarily on the screen and can easily altered or erased,it is sometimes referred to as softcopy

Answer:

function appendEvens( arr1, arr2) {

   for (let i in arr1){

       if (i%2 == 0){

           arr2.push(i);

       }

   }

}

Explanation:

The defined javascript function "appendEvens" is a function that returns undefined. It accepts two arrays and pushes the even numbers from the first array to the second.

Answer and Explanation:

import java.util.Scanner;

public class convertToBinary {

public static String declToBin(int value){

if(value == 1){

return declToBin((value/2) + "" + (value%2);

}

else{

declToBin((value/2) + "" + (value%2);

}

}

public static void main(String args[]){

int number;

Scanner change = new Scanner(System.in);

System.out.print("Enter decimal value: ");

number = change.nextInt();

System.out.println(declToBin(number));

}

}

The recursive function declToBin(int value) keeps executing code until value==1. Recursive functions reduces lines of code and makes it more efficient.

Note: Decimal is number in base 10(denary). To convert a decimal number to base 2(binary), we keep dividing the decimal number entered by the user by 2 until the result is zero(when the number divided is one)

We use the Java programming language here. First we import the Scanner object(import.java.util.Scanner). We use the method nextint() from the object to convert the string value entered by the user to int value( because our declToBin function takes an int parameter).

Python is an interpreted, object-oriented, high-level programming language with dynamic semantics.

Python is a high level language compared to bytecode.

Hence, being an interpreted language, which is not subject to processor, makes Python a high-level language. Also, Python offers convenience of code readability -- which makes the syntax of the program much easier and shorter, resulting in less coding steps for developers than imposed by Java or C++.

Python is an interpreted, interactive, object-oriented programming language. It incorporates modules, exceptions, dynamic typing, very high level dynamic data types, and classes.

The output of the range function is a sequence, which is a list of integers. The range created in the sequence of number is [0, 1, 2]. Hence option D is correct.

Integers are defined as a whole number that can be positive, negative, or zero and is not a fraction. Your integer can be written in a number of different ways. Write your integer, for instance, in standard form (such as 63), extended form (such as 100+50+2, which would be 152 in standard form), or written form (such as one thousand two hundred thirteen).

Pass range start and stop values () such as range (0, 6). Here, start is equal to 0 and stop is equal to 6. Send range the step value () the move Put the increment in. For accessing each integer, use a for loop. To iterate and access a series of numbers returned by a range(), use a for loop.

Thus, the output of the range function is a sequence, which is a list of integers. The range created in the sequence of number is [0, 1, 2]. Hence option D is correct.

Explanation:

The problem lies within your if statement. You're using a single equals sign when you should be using two.

if (operation == 1)

Two equal signs is a comparison operator. It checks to see if one value equals another value. In your case, its checking if operation equals 1. But, this only solves half the problem. Operation is a string and you need to compare it to a string.

if (operation == "1")

<textarea wrap="hard" cols="30" rows="5"></textarea>

Explanation:

A textarea element or tag is a form tag element of a HTML file. It is used to ask for input value from a user in a webpage. The textarea tag has an opening and a closing tag.

The 'cols' attribute is used to set the column length while the 'rows' attribute sets the row length of the textarea element. The 'wrap' attribute has three options namely; soft, hard, and off. 'soft' adds the textarea wrapping, 'hard' sets off the box wrapping but only wraps each line, while the 'off' option removes all wrapping in the tag.

Brute force

Explanation:

The two types of attack on an encryption algorithm are cryptanalysis, based on properties of the encryption algorithm, and brute force which involves trying all possible keys.

In brute force attacks there is the issue of using different keys and this is because the attacker is trying to guess the passwords used in the system in order to have it compromised.
