Below is the game code written in cpp. This is the first time I have consciously used pointers. I can't handle the logic of winning. I have no idea how to solve this in a different, more accessible way. I know that such straining of if statements is bad and the code is unmaintable. I realize that for some reasons you can't use cls. What's the alternative?
#include <iostream>
char square[10] = { '0','1','2','3','4','5','6','7','8','9' };
int Checkwin();
void Board();
int Choice(char mark, char* square, int choice);
void showLeftNumbers(char sqiare[]);
int main()
{
int player = 1, i, choice;
char mark;
do
{
int correctChoice = 1;
Board();
player = (player % 2) ? 1 : 2;
mark = (player == 1) ? 'X' : 'O';
int triesCount = 0;
do
{
std::cout << "Player " << player << ", enter a number: ";
std::cin >> choice;
correctChoice = Choice(mark, &square[choice], choice);
triesCount++;
if (triesCount > 2) showLeftNumbers(square);
} while (correctChoice == 1);
i = Checkwin();
player++;
} while (i == -1);
Board();
if (i == 1)
std::cout << "==>\aPlayer " << --player << " win ";
else
std::cout << "==>\aGame draw";
std::cin.ignore();
std::cin.get();
return 0;
