The distance a vehicle travels can be calculated as follows: distance = speed * time for example, if a train travels 40 miles-per-hour for three hours, the distance traveled is 120 miles. write a program that asks for the speed of a vehicle (in miles-per-hour) and the number of hours it has traveled. both values are assumed to be integers. it should use a loop to display the distance a vehicle has traveled for each hour of a time period specified by the user. for example, if a vehicle is traveling at 40 mph for a three-hour time period, it should display a report similar to the one that follows: hours distance traveled 1 40 2 80 3 120 do not accept a negative number for speed and do not accept any value less than 1 for time traveled.

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).
