A company wants to transmit data over the telephone, but they are concerned that their phones may be tapped. All of their data is transmitted as four-digits. They have asked you to write a program that will encrypt their data so that it may be transmitted more securely. Your program should read a four-digit integer and encrypt it as follows: 1. Replace each digit by (the sum of that digit and 3) modulus 10. Then 2. Swap the first digit with the third, and swap the second digit with the fourth. 3. Print the encrypted integer.

Answers

Answer 1

Answer:

def encrypt_digit(digit):

   if type(digit) is int or float:

       digit = str(digit)

   hold = list()

   for x in digit:

       d = str((int(x) + 3)%10)

       hold.append(d)

   first = hold.pop(0)

   second = hold.pop(0)

   third = hold.pop(0)

   fourth = hold.pop()

   print(int("".join([third,fourth, first, second])))

encrypt_digit(7836)

Explanation:

The python function accepts a four-digit parameter which represents the data transmitted over the company's telephone network. The function encrypts the data by adding 3 to each digit and getting the modulus of division 10, then the digits are swapped and printed out encrypted and ready for transmission.

Answer 2

Encryption are used to protect data and files when they are is being transmitted

The encryption program written in Python, where comments are used to explain each line is as follows:

#This gets input for the number

num = int(input())

#This converts the number to string

digit = str(num)

#This creates a list

myList = list()

#This encrypts the number, and add the numbers to a list

for i in digit:

   d = str((int(i) + 3)%10)

   myList.append(d)

#This prints the result of the encryption

print(int("".join([myList[2],myList[3], myList[0], myList[1]])))

Answer:

Question 4 => 4th answer: The first line should be for x in range (7, 10):

Question 5 => 2nd answer: 14 16 18 20 22 24 26 28 30 32

Explanation:

Question 4

"for" loops always need a variable (like "x") defined to iterate with different values.  for x in range (7, 10): makes x to take values 7, 8, 9 and 10 successively  and execute print(x) each time.

Question 5

The expression x in range (7, 16) makes x to take values from 7 up to 16 inclusive. So for each iteration it will execute print x*2 which prints the double of the actual value for x. Starting with x=7, it will print 14, then with x=8 will print 16, and so on. All values are shown on the table below:

X       Prints

7        14

8        16

9        18

10       20

11       22

12       24

13       26

14       28

15       30

16       32

The code segments are illustrations of loops.

4: The first line should be for x in range(7,10):5: The output is 14 16 18 20 22 24 26 28 30

The syntax of a for loop is:

for variable in range (begin,end+1):

The loop in question (4) is given as:

for range (7,10)

This means that, the variable is missing.

So, the first line of the code segment should be

for x in range(7,10):

For question 5, the value of x would range from 7 to 15.

The print statement prints twice x, followed by a space.

So, the output would be 14 16 18 20 22 24 26 28 30

The _________ operator returns the distance in bytes, of a label from the beginning of its enclosing segment, added to the segment register.a) TYPEb) SIZEOFc) OFFSETd) LENGTHOFe) PTR

Answers

Answer:

C. Offset.

Explanation:

An offset operator can be defined as an integer that typically illustrates or represents the distance in bytes, ranging from the beginning of an object to the given point (segment) of the same object within the same data structure or array. Also, the distance in an offset operator is only valid when all the elements present in the object are having the same size, which is mainly measured in bytes.

Hence, the offset operator returns the distance in bytes, of a label from the beginning of its enclosing segment, added to the segment register.

For instance, assuming the object Z is an array of characters or data structure containing the following elements "efghij" the fifth element containing the character "i" is said to have an offset of four (4) from the beginning (start) of Z.

We use printf() function

with %d format specifier to display the value of an integer variable,

with %c to display character,

With %f for float variable,

with %s for string variable,

with %lf for double and

with  %x for the hexadecimal variable.

Strspn() is often used to calculate the number of identical characters in both string and escape, whether the str1 does not match the str2 characters.

If the above statement is cued into a c compiler, it will thus return an error.

When you read in data from a file using the read() method the data is supplied to Python in the form of:
A. A list of Strings
B. A String
C. A list of lists
D. Raw ASCII values

Answers

Answer:

B. A String

Explanation:

Remember, there are other methods or ways to read data from a file such as readlines(), and the for ... in loop method.

However, if you read in data from a file using the read () method the data would be supplied to Python in the form of a String (or single String). This is the case because a String supports only characters, unlike lists that could contain all the data types.

Using the read() method in python is used to read in files such as text files, csv and other file types. The read() method will render the read in data as as a string.

In general, the read in data from the file is supplied in the form of a string, however, depending on the version of python which is being used, the string type may vary.

When using python 2, the data is supplied as a bytestring while the data is supplied a unicode string in python 3.

Hence, the read() method renders data as a string.

Given two integer arrays, largerArray with 4 elements, and smallerArray with 3 elements. What is the result after this code executes?for = 0; i < 45 ++) { LargerArray) = smallerArray(); A. All of the elements of secondArray will get copied to firstArray. B. Error: The two arrays are not the same size. C. All the elements of firstArray will get copied to secondArray D. Some of the elements of firstArray will get copied to secondArray,

Answers

Answer:

A. All of the elements of secondArray will get copied to firstArray.

Explanation:

The correct iteration code is:

for(i =0; i<4;++i) {

largerArray[i] = smallerArray[i];

}

From the question, we understand that the largerArray has a size of 4 elements while the smallerArray has a size of 3 elements

Take for instance largerArray is {1,2,3,4} and smallerArray is {5,6,7}

Next, we analyze the loop

1. for(i =0; i<4;++i) {  --->This iterates from index 0 to index 3

2. largerArray[i] = smallerArray[i]; ---- > This assigns the elements of the smallerArray to largerArray.

However, it should be noted that the smallerArray has a maximum index of 2 while the largerArray has a maximum index of 3

The content of largerArray after the iteration will be:

largerArray = {5,6,7,5}

This is so because,

When i = 0

largerArray[0] = smallerArray[0] = 5

When i = 1

largerArray[1] = smallerArray[1] = 6

When i = 2

largerArray[2] = smallerArray[2] = 7

When i = 3

largerArray[3] = smallerArray[0] = 5

Notice that the last iteration refers to smallerArray[0]; this is so because index 3 do not exist in smallerArray. Hence, the index will be returned to the first index of the smallerArray

Taking largerArray as the firstArray and smallerArray as the secondArray.

We can conclude that option A answers the question because all elements in smallerArray is copied to firstArray
