Tic tac toe c++

Question

I created a tic tac toe game with a 2d array, but I needed to create it with a vector. I researched 2d vectors or the technical term "vector inside a vector", but I wasn't clear on how I could turn my code into a vector or if I would have to redo the whole program. Also, I need it to print draw or tie if no one wins, but it keeps running if the game is tied.

Any advice would be greatly appreciated

#include <iostream>
using namespace std;

char arr[3][3] = { '*', '*', '*', '*', '*', '*', '*', '*', '*' };
char player = 'X';

void Draw()
{

cout << "Tic Tac Toe " << endl;
for (int i = 0; i < 3; i++)
{
for (int j = 0; j < 3; j++)
{
cout << arr[i][j] << " ";
}
cout << endl;
}
}
void Input()
{
int a;
cout << "Select a location: ";
cin >> a;

if (a == 1)
arr[0][0] = player;
else if (a == 2)
arr[0][1] = player;
else if (a == 3)
arr[0][2] = player;
else if (a == 4)
arr[1][0] = player;
else if (a == 5)
arr[1][1] = player;
else if (a == 6)
arr[1][2] = player;
else if (a == 7)
arr[2][0] = player;
else if (a == 8)
arr[2][1] = player;
else if (a == 9)
arr[2][2] = player;
}
void TogglePlayer()
{
if (player == 'X')
player = 'O';
else
player = 'X';
}
char Win()
{
//first player
if (arr[0][0] == 'X' && arr[0][1] == 'X' && arr[0][2] == 'X')
return 'X';
if (arr[1][0] == 'X' && arr[1][1] == 'X' && arr[1][2] == 'X')
return 'X';
if (arr[2][0] == 'X' && arr[2][1] == 'X' && arr[2][2] == 'X')
return 'X';

if (arr[0][0] == 'X' && arr[1][0] == 'X' && arr[2][0] == 'X')
return 'X';
if (arr[0][1] == 'X' && arr[1][1] == 'X' && arr[2][1] == 'X')
return 'X';
if (arr[0][2] == 'X' && arr[1][2] == 'X' && arr[2][2] == 'X')
return 'X';

if (arr[0][0] == 'X' && arr[1][1] == 'X' && arr[2][2] == 'X')
return 'X';
if (arr[2][0] == 'X' && arr[1][1] == 'X' && arr[0][2] == 'X')
return 'X ';

//second player
if (arr[0][0] == 'O' && arr[0][1] == 'O' && arr[0][2] == 'O')
return 'O';
if (arr[1][0] == '

Answer 1

Yes: select all in IDE/editor on computer, copy on computer, create c++ SoloLearn playground file, select all in SL, paste to overwrite default code in SL, save to file, and copy web link after save works.

Answer 2

First, advice link your code to your posts so we get it all. Since your using a browser you can copy the link and paste it here.

Answer 3

Did you try Hatsy Rei's suggestion yet?

Answer 4

For a 2d char array declared and initialized as:

char arr[3][3] = { {'*', '*', '*'}, {'*', '*', '*'}, {'*', '*', '*'} };

Just change the declaration of arr to:

std::vector<std::vector<char>> arr = { {'*', '*', '*'}, {'*', '*', '*'}, {'*', '*', '*'} };

They can be accessed in a similar manner:

std::cout << arr[0][2];

Answer 5

Hasty Rei, Thank you, it works the same as the 2d array, not sure what I did last night to get the errors I got

Answer 6

John Wells, I am not sure how I would link my code, it is saved on my computer, but its not on any site other than my student account. Is there a way to upload code?

Answer 7

This is the link to the complete code
