A [answer] cipher is typically implemented by performing a AND mathematical operation at least two bytes at a time. A. stream B. DES C. key D. block

Many user-created passwords are simple and easy to guess. Write a program that takes a simple password and makes it stronger by replacing characters using the key below, and by appending "q*s" to the end of the input string. i becomes ! a becomes @ m becomes M B becomes 8 o becomes . Ex: If the input is: mypassword the output is: Myp@ssw.rdq*s   How do I write this in C++

In C++, how do you encrypt one character in a file read into the code?

What happens if you enter a string greater than eight characters? How can a buffer overflow be avoided?

would you write the c++ program which is written in pseudocode:   Code 1: input file A contains numeric values output File A is sorted a ← read Value (A) while not End Of File (A) performs b ← read Value (A) if a > b then return false end if a ← b end while return true   Code 2: input files A and B are sorted according to Code 1 output The file C contains all values from A and B in sorted order a← read Value (A) b ←read Value (B) while not End Of File (A) And not End Of File (B) perform. Determines which value to write to C if a < b then Write a to C a ← read Value (A) else Write b to C b← read Value (B) end if end while. A or B is over, write both clearly while not End Of File (A) performs Write a to C a← read Value (A) end while while not End Of File (B) performs Write b to C b← read Value (B) end while

Full Implementation (user input in red) Welcome to the Caesar Cipher This program encrypts and decrypts text using Caesar Cipher. Would you like to encrypt (e) or decrypt (d): d Would you like to read from a file (f) or the console (c)? c What message would you like to decrypt: LIPPS ASVPH What is the shift number: 4 HELLO WORLD Would you like to encrypt or decrypt another message? (y/n): y Would you like to encrypt (e) or decrypt (d): e Would you like to rea from a file (f) or the console What message would you like to encrypt: Hello World What is the shift number: 4 (c) ? c LIPPS ASVPH Would you like to encrypt or decrypt another message? (y/n): y Would you like to encrypt (e) or decrypt (d): e Would you like to read from a file (f) or the console (c) ? f Enter a filename: something_silly.txt Invalid Filename Enter a filename: messages.txt What is the shift number: 4 6 Output written to results.txt Would you like to encrypt or decrypt another message?
