Select the correct statement(s) regarding DCE and DTE interfaces. a. the DCE and DTE convention describes devices and not interfaces b. to establish data flow, DTE interfaces must always be connected to other DTE interfaces, and DCE interfaces must always be connected to other DCE interfaces c. DCE and DTE device descriptions are unique to IEEE 802.3 Ethernet LANs d. the DCE and DTE convention describes the interfaces associated with devices; a single device may have both a DTE and DCE interface to enable correct data flow

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.
