(c) Write a Haskell program that:
• Reads two files, called "input1.txt" and "input2.txt".
• Interleaves the lines of the two files.
• Writes the result to a file called "output12.txt" .
You may make use of any functions in the Reference (pp5-7).
(python)
10. Create a function based on the following information:
Your mission is to encrypt a secret message (text only, without special chars like "!", "&", "?" etc.) using Caesar cipher where each letter of input text is replaced by another that stands at a fixed distance. For example ("a b c", 3) == "d e f"
Input: A secret message as a string (lowercase letters only and white spaces) and number to move text
Output: The same string, but encrypted
Return: The same string, but encrypted
I need help with this:
(Address book) Write a program that stores, retrieves, adds, and updates addresses as shown in Figure 17.20. Use a fixed-length string for storing each attribute in the address. Use random access file for reading and writing an address. Assume that the size of name, street, city, and zip is 32, 32, 20, 2, 5 chars, respectively.

The following three characters {*,$, :} in addition to spaces are not allowed in file names. If any of these four characters appears in a file name, it is replaced by a hyphen (-). Examples: "new file" → "new-file" "important$file" → "important-file" "abc$def gh:ij*klm.txt" → "abc-def-gh-ij-klm.txt" "exam.doc" →→ "exam.doc" i.
