你能解释一下这段代码吗,记住写它的人是用它来教我前缀和后缀递增之间的区别
int main()
{
const int ROWS = 3;`enter code here`
const int COLUMNS = 3;`enter code here`
char board[ROWS][COLUMNS] = {{'O', 'X', 'O'}, {' ', 'X', 'X'}, {'X', 'O', 'O'}};
cout << "Here’s the tic-tac-toe board:\n";
int i = 0;
int j = 0;
while ( i < ROWS) {
cout<<board[i][j];
j++;
if (j >= COLUMNS) {
j = 0;
i++;
cout << endl;
}
}
}
