The code below only outputs the sample input, i need to add a file reader that reads a txt file with more than 5 (like a 1000 names )names and outputs them based on their class. read the instruction on the attchment pleace and add comments on your code.

Sample Input Sample output queen elizabeth mom upper upper lower middle class. inom dad: middle middle lower middle class. dad. queenelizabeth upper upper class unclebob chair lower lower class chair unclebob: middle lower middle class Sample Input Sample output 10 mona. rich lower upper class mary rich mona: upper upper class Charles dave middle lower class tom Charles middle class violet tom: middle class William: lower middle class William carl Carl lower class dave violet middle class frank frank: lower class mary: upper class
