Need some help writing a game code

[GhostCas]

Update March 9th: I think i am finally getting somewhere with this program still a lot of mistakes. Thanx for all the help really appreciate it. Will update op with my code soon

[GhostCas]

Bump. Still trying but anything helps :)

you would need two inputs from the user. the position where they want to place the number and the actual value of the number.

so example user 1 enters 1 for the position it will map to grid[0][0] and enter 9 so you fill grid[0][0] with 9.

you also need to do some checking if the number has already been used.

i would store the numbers in a vector and then remove it once its used.
if user inputs a value that is not in your storage report an error.

this game is a bit complex. you need to break it down into small steps.

you would need a while loop to repeat the whole process of
getting input from user -
checking move was valid -
redrawing your board
check for win condition.

this should get you started.

Ok i'm at work I'll get some more done tonight and then update the post. Thanks a lot.

Let us play it after you finish. It seems to be interesting. :D

BTW. the operator for input is >> not << like on line 24: cin << num1 << endl;

I do not know so well C++ but I thing you wrote code wrong. Primarily need creat matrix

const int row=3,col=3;
	int mtx[row][col]={0,1,2,3,4,5,6,7,8};
for(int i=0;i<row;i++)
{
	for(int j=0;j<col;j++)
	{
		
		mtx[i][j];
	}
	cout<<endl;
}

then need creat loop "player1" & "player2"

int num;
string s[2]={"player1 enter number between 1&9","player2 enter number between 1&9"};

for(int i=1;i<=4;i++)
{
cout<<s[0]<<endl;
cin>>num;
	for(int j=1;j<=5;j++)
	{
		cout<<s[j%2]<<endl;
		cin>>num;
	}
	break;
}

after you must assay equal sum number

if(15==sum)
{
	cout<<"you win";
}
else if(15!=sum)
{
	cout<<"your sum number "<<sum<<"you loser";

}

join this blocks and finalize code

Ok I used everyones suggestions and came up with another draft!
p.s. I tried to use the vectors and it didn't really work out (Didn't learn much about vectors yet) so I am still trying to implement vectors into my code, slowly learning. More feedback would be greatly appreciated. Thank you for all the help.

Bump still looking for some advice on my updated code

[Thomas1965]

Can you post your updated code and tell us what problem is there ?

#include <iostream>
#include <play.h>
#include <check.h>

I have started a section of the game loop for you. hope you can follow the example.
I will build up more sections when I get the time to do it.

I have noticed in your check for win condition function.
you need to sum up the numbers instead of &&

  if ((grid[1] + grid [2] + grid [3]) == 15)

#include <iostream>
#include <vector>
#include <algorithm>

using namespace std;

vector<int> matrix_options;
vector<int> box_options;
int matrix[3][3];

// still need to implement which player made the turn.
// x for player 1
// o for player 2

//   1x   |     2o  |   3
// [0][0] |  [0][1] | [0][2]
//________|_________|_______
//    4   |     5   |   6
// [1][0] |  [1][1] | [1][2]
//________|_________|_______
//    7   |     8   |   9
// [2][0] |  [2][1] | [2][2]
//        |         |

void display_matrix()
{
    cout << endl;

    cout << " " << matrix[0][0]  << " | " << matrix[0][1] << " | " << matrix[0][2]  << endl;
    cout << "------------" << endl;
    cout << " " << matrix[1][0]  << " | " << matrix[1][1] << " | " << matrix[1][2]  << endl;
    cout << "------------" << endl;
    cout << " " << matrix[2][0]  << " | " << matrix[2][1] << " | " << matrix[2][2]  << endl;

}



void populate_selection()
{
    for(int i=1; i < 10; i++)
    {
        box_options.push_back(i);
        matrix_options.push_back(i);
    }
}

void display_options(vector<int>& storage)
{

    // display list of available options
    for(int i=0; i < storage.size(); i++)
    {
        cout << storage[i] << " ";
    }

    cout << endl;
}

// first argument is passed by reference
// second argument is passed by value
void remove_option(vector<int>& storage, int value)
{
    // removes a value from storage
    auto it = std::find(storage.begin(), storage.end(), value);

    if(it != storage.end())

        storage.erase(it);

        break;

        case 2:
        {
            matrix[0][1] = value;
        }
        break;

        case 3:
        {

what are your rules for the win condition?

it doesn't look very exciting if its just a sum of 15 because a player can win in exactly 2 turns.

[GhostCas]

I want to make it more exciting but trying to make it work first. My problem now is that My matrix prints but it is not updating with the number that the user is printing.

[rafae11]

Have you tried the example i've showed you?

Can you post the updated source code that you are using.
