The difference between a true (online) ups and a standby ups (battery backup) is (a). the online ups is always producing output ac voltage from the battery, the standby ups only does so when utility power drops below a threshold (b). the online ups only produces output ac voltage from the battery when the utility voltage drops below a threshold, otherwise it simply routes utility voltage to the output (c). the online ups is able to signal the computer when it is running on battery, the standby ups cannot do this. (d). there is no difference

The editing of digital photos us about the same level of difficulty as editing an analog photo

Write a modular program (no classes yet, just from what you learned last year), that allows two players to play a game of tic-tac-toe. use a two-dimensional char array with 3 rows and 3 columns as the game board. each element of the array should be initialized with an asterisk (*). the program should display the initial board configuration and then start a loop that does the following: allow player 1 to select a location on the board for an x by entering a row and column number. then redisplay the board with an x replacing the * in the chosen location. if there is no winner yet and the board is not yet full, allow player 2 to select a location on the board for an o by entering a row and column number. then redisplay the board with an o replacing the * in the chosen location. the loop should continue until a player has won or a tie has occurred, then display a message indicating who won, or reporting that a tie occurred. player 1 wins when there are three xs in a row, a column, or a diagonal on the game board. player 2 wins when there are three ox in a row, a column, or a diagonal on the game board. a tie occurs when all of the locations on the board are full, but there is no winner. input validation: only allow legal moves to be entered. the row must be 1, 2, or 3. the column must be 1, 2 3. the (row, column) position entered must currently be empty (i.e., still have an asterisk in it).
