Write a program that uses 3 command line arguments to search a list of float numbers in a file and prints out the result of whether the number was found or not on the console. Also, it prints the array in the reverse order (not sorted but reverse order of how the numbers were read in). The first argument is the name of the input file which has the numbers to be searched, the second is an integer specifying how many numbers are in the input file and the third argument is the float number being searched for. Use dynamic memory allocation for the array and use a function (that returns a boolean value) to do the searching. Also make sure in the beginning of your program, that the program will execute only if exactly three arguments (other than executable name itself) are specified at the command line.

I'm perplexed by the idea of two-factor authentication. To what degree does it contribute to password security?

How can we tell if one method of authentication is safer than another?

Encrypt the message DEFEND using the RSA system with n = 43*59 and e = 13.  First translate each letter into an integer and group together pairs of integers, so you have three 4-digit numbers (padding 0’s in the front if necessary).  Work with each of these numbers to encrypt them.  The ciphertext should also be three 4-digit numbers.

The following is a message encrypted using affine cipher and you know the multiplicative key is 7 and the additive key is 3. Decrypt the message and show all your work.

you were sent this message to decrypt using RSA: 543221766605541460 Your public information is n = 958297 and e = 65537.Your private information is p = 967 and q = 991 what is ? (n)?

Authentication in today's internet world seems like a daunting endeavor; please explain the reasons why this is the case.

I'm having trouble getting this book's entry code. Is there any way you could help me find it or tell me how to look for it on my Yuzu account?
