Write a limited c # program that prompts a user to provide their username and password. assume usernames and passwords are alphanumeric with a length of 8. provide a first level of obfuscation by converting each character in the username to an array of 8 integers representing the ascii values for each alphanumeric value in the username. do the same to the password. then multiply each value in the array by its position in the array (from 1 to 8). print the arrays to view the values and verify their lack of readability. decrypt the arrays, by reversing the process, ie, dividing each array element by its position (from 1 to 8) in the array. then convert the values in the array elements back to readable text and print them.

i guess the correct option is letter a.

use contrasting font sizes, but the same font style

we can all learn from our past mistakes because we all have different ways of learning different types of techniques. my way may or may not another classmate remember and have the repetition to acknowledge such standard. such as remembering acronyms. using abbreviations to us remember keep things in order in our memory. this us figure out what comes next in the sequence. if so, what we have is a sentence of just letters all in caps. we either know the meaning or have no idea what it stands for. most of the time we know the meaning and context. but most of us who don't know, should learn by having a quick glance at what needs to be remembered. such as repetition in the memory for acronyms. one way that me, is the fact that i'm always doing math and english assignments. so we have to remember specific meanings such as soapstone for documents, such as citing correctly. or pemdas for doing the equations correctly, even if it's the super long way. this works for everyone. you just have to find what works for you by practicing and repetition daily.
