// //
// Description: A game of tic-tac-toe. Players take turns putting an X //
// or an O in a matrix. Whoever fills in all X's or O's in //
// a row, column, or diagonal first wins. Game ends when //
// there is a tie. Size of matrix is defined by ROW and COL //
// in the constants.h header file. ROW and COL must be //
// equal to each other. The matrix can be any size, e.g. //
// 10 x 10, so feel free to modify the ROW and COL //
// constants. Enjoy, and have fun! //
// //
// Version: 1.1 //
// //
// Input parameters: None //
// //
// Returns: -1 if problems were encountered //
// 0 on success //
// //
