Which of the following variables are valid? Give reasons for those which
are invalid ​

Answer:

Written in Python

print("Enter strings: ")

str1 = input()

str2 = input()

if len(str1) == len(str2):

     for i in range(0,len(str1)):

           print(str1[i]+str2[i], end='')

else:

     print("Error")

Explanation:

Prompts user for two strings

print("Enter strings: ")

The next two lines get the input strings

str1 = input()

str2 = input()

The following if condition checks if length of both strings are the same

if len(str1) == len(str2):

If yes, this iterates through both strings

     for i in range(0,len(str1)):

This prints the the characters of both strings, one character at a time

           print(str1[i]+str2[i], end='')

If their lengths are not equal, the else condition is executed

else:

     print("Error")

import java.util.Scanner;

public class JavaApplication89 {

   public static void main(String[] args) {

       Scanner scan = new Scanner(System.in);

       System.out.println("Enter Strings:");

       String word1 = scan.nextLine();

       String word2 = scan.nextLine();

       String newWord = "";

       if (word1.length() != word2.length()){

           newWord = "error";

       }

       else{

           for(int i = 0; i < word1.length(); i++){

               newWord += word1.charAt(i)+""+word2.charAt(i);

           }

       }

       System.out.println(newWord);

   }

}

This is the java solution. I hope this helps!

Answer:

first statement makes most sense.

Explanation:

When checking numeric values in computer memory, decimal makes sense because you use decimal numbering every day. --> sounds OK.

When checking words in computer memory, decimal makes sense because you use decimal numbering every day.  --> doesn't make sense

When comparing values in a computer program, decimal numbering makes sense because it is always shorter than hexadecimal. --> Not true

When checking words in computer memory, decimal numbering makes sense because it is easier than hexadecimal. --> Hexadecimal would be easier when inspecting computer words, because you can easily see the byte alignment of the values.

I don't know if the print statement is indented into the for loop.

If the print statement is indented like this:

numA = 1

for count in range(3,5):

   numA = numA * count

   print(numA)

The output will be:

Answer:

The correct answer is:

c. var leftOver = numApples % 3

Explanation:

JavaScript uses different operators to perform various mathematical functions. In mathematics, when a number is not completely divisible by other the answer contains the remainder and quotient.

Modulus operator is used in JavaScript to find the remainder.

For example,

20/3 will return the quotient which is 6 while

20%3 will return the remainder which is 2

In the given statement, we have to find the number of remaining apples after being divided into three people

So,

Number of apples mod 3 will give us the number of remaining apples.

Hence,

The correct answer is:

c. var leftOver = numApples % 3

Explanation:

As humanity is improving technological wise most jobs will be replaced and other jobs would come into play and in order for individuals to become employed in jobs that will be available in the future to come they will have to have a degree in computer science or know how to operate computers.

Answer:

No not all careers and professions require computer science

Explanation:

There are so many careers, many in which you may not sit in front of a computer. If you become a farmer, janitor, teacher or more you may not need computer science skills.

Task 1:

float75 = float(75)

string75 = "75"

# you cannot add together a number and a string because a string has no inherent numerical value like a number does.

Task 2:

num = float(input("Enter a number"))

print(num**2)

Task 3:

num = int(input("Enter an integer: "))

print("When you divide "+str(num)+" by 7, the quotient is "+str(num//7)+" and the remainder is "+str(num%7)+".")

Task 4:

gigs = int(input("How many gigabytes does your flashdrive hold? "))

print("A flashdrive with "+str(gigs)+ " gigabyte(s) holds "+str(gigs*8589934592)+" bit(s).")

For task 4, you might have to change the number 8589934592 to something else. I'm not entirely sure how many bits are in a gigabyte. I hope this helps though.
