Encrypt Caesar cipher is a kind of substitution cipher. Instead of using a substitution table, the alphabets are rotated by a number (a key). For example, if the key is 3, plaintext alphabet a would become d, and plaintext alphabet z would become c. Write a program that implements the Caesar Cipher. You program will first prompt for the key and then for the mode (E for encryption and D for decryption) and finally for the message to be encrypted / decrypted. Your program will then output the encryption / decryption message. For this question, the input message may consists of any character, the program should encrypt or small letter case a to z only. All other characters should be kept intact after encryption or decryption.
A company wants to transmit data over the telephone, but it’s concerned that its phones may be tapped. All of its data is transmitted as four-digit integers. It has asked you to write a script that will encrypt its data so that the data may be transmitted more securely. Your script should read a four-digit integer entered by the user in a prompt dialog and encrypt it as follows: Replace each digit by (the sum of that digit plus 7) modulus 10. Then swap the first digit with the third, and swap the second digit with the fourth. Then output HTML5 text that displays the encrypted integer. In HTML and JavaScript

Two friends are exchanging messages through regular post mail. They don’t want anyone to understand their messages in case anyone read them. The messages are in the form of an array of characters, where each character has a numeric value as illustrated in the below lookup table.

Here is the assignment Write a program that prints the multiplication table but inserts a randomly generated incorrect value between 1 and 50 into a cell whose row and column are randomly selected. Make sure the program does insert an incorrect value. For example, if row and column of 3 and 4 are randomly selected, keep generating a random number to print for that location until it's not the right value of 12. Then, ask the user to tell where in the table the incorrect number is located by entering the row and column of the incorrect number. Print whether the user was right or not. If he or she was right, ask for and read the correct value; if not, the program must give the correct location and the correct number. My main issue: is how to set up the multiplication table? I've only learned the basics in C++ (loops and if statements).

Encode the number using the given public key. Encode the number M = 14 using the public key n = 77 and e = 13. Assume you are encoding the number using the RSA cryptosystem. Note: You can use the Modular Exponentiation calculator to help with the calculation. a 46 (mod 77), encoded number = 46 47 (mod 77), encoded number = 47 48 (mod 77), encoded number = 48 d. 49 (mod 77), encoded number = 49

Write a program that reads the user's first name and last name, and then use them to create a UPM email for the user. If the total number of characters in the user's full name, (first name + last name), is less than 10 letters, you should use the full name to create the user’s email. The general format of the user’s email should look like this: firstName.lastName@upm.edu.sa For example: First name = Ali Last name = Omar Total number of letters in both first and last names = 7 letters (<10 letters) Output = omar.ali@upm.edu.sa If the number of characters in the user's full name, (first name + last name), is greater than or equal to 10 letters, you should only use the first character in the user’s first name, and the whole last name to create an email. For example: First name = Abdullah Last name = Omar Total number of letters in both first and last names = 12 letters (>=10 letters) Output = a.omar@upm.edu.sa Note: you can assume the user will always enter lowercase letters
On a piano, a key has a frequency, say f0. Each higher key (black or white) has a frequency of fo* r, where n is the distance (number of keys) from that key, and r is 21/12) Given an initial key frequency, output that frequency and the next 3 higher key frequencies. Output each floating-point value with two digits after the decimal point, then the units ("Hz"), then a newline, using the following statement: printf("$0.21f Hz\n", yourValue); Ex: If the input is: 440.0 (which is the A key near the middle of a piano keyboard), the output is: 440.00 Hz 466.16 Hz 493.88 Hz 523.25 Hz Note: To compute the next 3 higher key frequencies, use one statement to computer = 2(1/12) using the pow function (remember to include the math library). Then use that r in subsequent statements that use the formula f = f0 *r¹ with n being 1, 2, and finally 3. O Run v main.c 1 2 3 int main(void) { #include Reset Lab Tutorial Ⓡ
Your local bank has decided to upgrade its ATM machines by incorporating motion sensor technology. The machines now interpret a series of consecutive dance moves in place of a PIN number. Create a program that converts a customer's PIN number to its dance equivalent. There is one dance move per digit in the PIN number. A list of dance moves is given in the code. Examples danceConvert("0000") danceConvert("3856") danceConvert ("9999") danceConvert("32a1") -> ["Shimmy", "Shake", "Pirouette", "Slide"] [ "Slide", "Arabesque", "Pop", "Arabesque" ] - - [ "Arabesque", "Shimmy", "Shake", "Pirouette" ] "Invalid input."
