7.3.1: Functions: Factoring out a unit-conversion calculation. Write a function so that the main() code below can be replaced by the simpler code that calls function MphAndMinutesToMiles(). Original main(): int main() { double milesPerHour; double minutesTraveled; double hoursTraveled; double milesTraveled; cin >> milesPerHour; cin >> minutesTraveled; hoursTraveled = minutesTraveled / 60.0; milesTraveled = hoursTraveled * milesPerHour; cout << "Miles: " << milesTraveled << endl; return 0; } 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 #include using namespace std; /* Your solution goes here */ int main() { double milesPerHour; double minutesTraveled; cin >> milesPerHour; cin >> minutesTraveled; cout << "Miles: " << MphAndMinutesToMiles(milesPerHour, minutesTraveled) << endl; return 0; } 1 test passed All tests passed Run

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.
