3. assume the following rules of associativity and precedence for expressions: precedence highest to lowest *, / +, –, & , mod – (unary) =, /=, < , < =, > =, > and associativity lowest left to right show the order of evaluation of the following expressions by parenthesizing all subexpressions and placing a superscript on the )to indicate order. for example, for the expression a + b * c + d the order of evaluation would be represented as ((a + (b * c)1 ) 2+ d)3 a. a * b - 1 + c b. a * (b - 1) / c mod d c. (a - b) / c & (d * e / a - 3) draw parse trees for the these expressions

What does a cascading style sheet resolve a conflict over rules for an element? a. the rule affecting the most content wins b. the rule affecting the most content loses c. the rule with the most specific selector loses d. the rule with the most specific selector wins

Consider the following code snippet: #ifndef cashregister_h#define cashregister_hconst double max_balance = 6000000.0; class cashregister{public: cashregister(); cashregister(double new_balance); void set_balance(double new_balance); double get_balance() const; private: double balance[12]; }; double get_monthly_balance(cashregister bk, int month); #endifwhich of the following is correct? a)the header file is correct as given. b)the definition of max_balance should be removed since header files should not contain constants. c)the definition of cashregister should be removed since header files should not contain class definitions. d)the body of the get_monthly_balance function should be added to the header file.

Design a class tictactoe that: holds the following information about the game: two-dimensional array (3 by 3), and winner. add additional variables as needed. includes the functions to perform the various operations on objects. for example, function to print the board, getting the move, checking if move is valid, determining if there is a winner after each move. add additional operations as needed. includes constructor(s). write the functions of the class, and write a program that uses the class. the program should declare an object of type tictactoe. the program will create the board and store it in the array. the program will allow two players to play the tic-tac-toe game. after every valid move update the array, check if there is a winner. if there is no winner and no tie, then print the board again to continue.
