Assume the following rules of associativity and precedence for expressions Precedence Highest *, /, not , &, mod (unary) and or, xor Lowest Associativity Left to right Show the order of evaluation of the following expressions by parenthesizing all subexpressions and placing a superscript on the right parenthesis to indicate order. For example, for the expression a +b* c + d the order of evaluation would be represented as ((a+ (b c)12+ d) 3 b. a * (b-I) / c mod d
c. (a -bc & (d e/ a - 3) d. -a or c-d and e e. a > b xor c or d <= 17 (10 points) Show the order of evaluation of the expressions of the previous, assuming that there are no precedence rules and all operators associate right to left.

Ihave a music player on my phone. i can buy songs, add them to playlists and play them. obviously it would be redundant to store each song in each playlist; each playlist is just a list of pointers to the songs. for this lab you will simulate this behavior. your program will need to have options to: add songs to the system library (you will store the text of the first line of the song, rather than the audio) add playlists add songs to a playlist list playlists play a playlist list all of the songs in the library with a count of how many times each song has been played remove a song from a playlist remove a playlist remove a song from the library (and thus from all playlists that contain it) note that we will not be checking many error cases. in real programming this would be bad, you should usually try to recognize and respond to as many types of errors as you can. in the context of class we are trying to acquaint you with as many concepts as possible, so for the sake of educational efficiency we will not be checking most errors in this lab, you may assume that your user provides correct input. you may add all appropriate error testing if you wish, but we will not be testing for it.

Jason needs to learn a new web tool. he went through his books to understand more about it. now he wants hands-on experience with using that tool. what would him? jason can use websites where workspace is provided to test the results of your code.
