A company wants to transmit data over the telephone but is concerned that its phones may b tapped. It has asked you to write a program that will encrypt the data so that it may be transmitted more securely. All the data transmitted is 4 digit integers. Your program should read a four digit integer entered by the user and calls a function encrypt which takes four digits as arguments and encrypt it as follows . Replace each digit with the result of adding 4 to the digit and getting the remainder after dividing the new value by 10. . Calls another function swap which swaps the first digit with the third, and second digit with the fourth using pass by reference. Then it prints the encrypted integer.

(Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. Each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs, increment the counter variable that’s keeping count of the 1s that occur; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.
Securing data is very important. We are developing an encryption module for the communication system in C++. You are supposed to input data in a character array of size 100. After taking input in array pass this array to a function to encrypt. This function applies following encryption on data. For testing purposes, after encryption function is called, the main function should print the encrypted data in the array. Convert upper case letters to lower case and lower case letters to upper case. After conversion replace each alphabet with its next alphabet, for example “A” will be replaced by “B”, “B” will be replaced by “C”, and so on. Similarly “a” will be replaced by “b” etc. However, “Z” should be replaced by “A” and “z” should be replaced by “a”. Digits must be replaced by subtracting it from 9 for example 0 should be replaced by 9 (9-0=9), 1 should be replaced by 8 (9-1=8), 2 should be replaced by 7 (9-2=7)………… and 9 should be replaced by 0 (9-9=0). Spaces should be replaced by $…
The function doit(a,b,c,d) is a function that multiplies the smallest of its integers arguments by 2. If more than one arguments are equal and are the smallest, they are multiplied by 2. For example given a=5,b=3,c=7,d=9, doit (a,b,c,d) changes b to 6. Write the code of the function doit and test it.
NEED HELP WITH THIS import random print(random.randint(1,6)) #prints a number between 1 and 6. #or: x = random.randint(1,6) print(x) #prints a number between 1 and 6. write a python program that simulates a game with two dice roll based on their sum and value. Your program should: Define a function try_your_luck(dice1, dice2) that takes two arguments i.e., the numbers generated by randint() function (use randint twice). The random numbers should be passed to the function as argument The player wins some money, when: a. Sum of both dice is divisible by three, player wins $5 b. Same number on both die, player wins $10 c. For all other cases, print "try again" Player loses the game, when: a. Sum is greater than 10 and odd b. Sum is 7. Display an appropriate message for each case (player wins or loses).
I am doing a word guessing game where I have created a function that shuffles a word randomly. However, I want to create a function that will act as a clue when the user presses it; it will display the first word of the jumbled word. For example, if the word is - friends, The Jumbled word would be - siedfrn, with the function I already made. However, in order for users to get some help, they can press a number(4), and the needed function will result in the output to be- fiedsrn.
Write a function that adds two numbers. You should not use+ or any arithmeticoperators.
Write a function that asks the user how many Fibonacci num-bers to generate and then generates them. Make sure to ask the user to enter the numberof numbers in the sequence to generate. The Fibonacci sequence is a sequence of num-bers where the next number in the sequence is the sum of the previous two numbers inthe sequence. The sequence looks like this: 1, 1, 2, 3, 5, 8, 13,You could assign your input integer to a variable num by num = int (input ("Howmany numbers that generates?: "))• You have to consider exceptions, such as the input integer is zero, negative num-bers or floats.• Please submit your code and console screenshots to Bartleby. Code contain-ing syntax error will be graded zero.• Example: The prompt asks "How many numbers that generates?" If your input is10, then the function will return a list of 10 integers 1, 1,2,3,5,8, 13, 21, 34, 55
This code is for Python Write a program that reads text from the user and reverses the order of every number that appears in the text. For example: Hello! The number is 17. will become Hello! The number is 71. To help with this problem, first write a function rev(text) that takes a string of text and returns the reverse. For example, rev("Oranges") would return 'segnaro". You may create any addition function you need. You must create the rev function. Your program will ask for a string of text and reverse and number. A number is defined as any sequence of digits 0-9. Remember to use if name=="_main": so that ZyBooks can test your rev function. Here are two examples. Welcome to Digit Flipper Enter Some Text: Hello! The number is 17. Revised String: Hello! The number is 71. The input may not have any spaces at all to break up the text.

First write a function f to generate and return a random number between 0 to 100 In the main function, you keep calling function f until the returned value is less than 10 Then you should print out how many times the function f has been called. Note that every time f will only return a single random number, and the declaration of f is as follows: int f() For instance, if f returns 23, 89, 10, 1, then your program should print 4 on the screen. C++ language Hint 1. You can implement the function using different methods, like the static variable Hint 2. You can use the modular operator to shrink the generated random value, i.e., random() % 101 will guarantee the result is between 0 and 100.
a. Write a function named countDigits that accepts a positive integer as its parameter and returns the number of digits in that number. For example, the number 8546587 has seven digits, so the call countDigits(8546587) should return 7. You may assume that the value passed to your method is non-negative. b. Write a program to input an integer n and call the above function in part a if n is positive, else give 'Value must be Positive' message. Inputting will stop when 0 is entered.
Write a python function that will perform the basic calculation (addition, subtraction, multiplication and division) based on 3 arguments. They are: Operator (+', '-', '"', '*') . First Operand (any number) • Second Operand (any number) Your first task is to take these arguments as user input and pass the values to the function parameters. Your second task is to write a function and performs the calculation based on the given operator. Then, finally return the result in the function call and print the result. Input: "+" 10 20 Function Call: function_name("+", 10, 20) Output: 30.0
write a python program 9. You are a class teacher at a kindergarten school. As a task, you asked your students to write a paragraph. Unfortunately, you notice that most of the students did not use capital letters correctly. Your task is to write a function which takes a string as its only parameter and returns a new copy of the string that has been correctly capitalized. Your function should: Capitalize the first letter in the string Capitalize the first letter after a full-stop, exclamation mark or question mark • Capitalize the word “i" if it is in lowercase. Summary: You have to write a function that reads a string from the user and capitalizes. The string is then returned and displayed. Sample Input ('my favourite animal is a dog. a dog has sharp teeth so that it can eat flesh very easily. do you know my pet dog's name? i love my pet very much.') Sample Output My favourite animal is a dog. A dog has sharp teeth so that it can eat flesh very easily. Do you know my pet dog's name? I…
