Receiving exit code -1073741819 when program is ran - c

Question

I'm making a tic-tac-toe program in C. My code is listed below.
#include <stdio.h>
#include <conio.h>
char evaluateWinConditions(char board[3][3]);
int main(void)
{
puts("---");
puts("---");
puts("---");
char board[3][3] = {{"-"}}; // board
char key = 0; // stores key presses
// stores position of mouse pointer
int row = 1;
int column = 1;
// stores player turn
int player = 1;
printf("\033[%d;%dH", row, column);
while (evaluateWinConditions(board) == 0) {
key = _getch();
switch (key) {
case 'a':
column -= 1;
break;
case 'w':
row -= 1;
break;
case 'd':
column += 1;
break;
case 's':
row += 1;
break;
case ' ':
if (player == 1) {
printf("%c", 'X');
board[row][column] = 'X';
player = 2;
}
else {
printf("%c", 'O');
board[row][column] == 'O';
player = 1;
}
break;
}
printf("\033[%d;%dH", row, column);
}
printf("\033[5;1H");
if (evaluateWinConditions(board == 1)) printf("Player 1 wins.");
else printf("Player 2 wins.");
}
char evaluateWinConditions(char board[3][3])
{
if (board[0][0] == board[0][1] == board[0][2] ||
board[1][0] == board[1][1] == board[1][2] ||
board[2][0] == board[2][1] == board[2][2] ||
board[0][0] == board[1][1] == board[2][2] ||
board[0][2] == board[1][1] == board[2][0]) {
if (board[0][0] == "X") return 1;
else return 2;
}
else {
return 0;
}
}
When I compile the program, there's no errors. However, I receive a run time error with code -1073741819 when I run the program. I'm using Windows 10 64-bit and Visual Studio 2019. This error appears after about one second when I run the program. When I debug the program in Visual Studio, I receive an error on line 74 "Exception thrown: read access violation; board was nullptr"

Answer 1

The probable cause of the exception is a consequence of the nonsensical comparison board == 1 in the function call evaluateWinConditions(board == 1). The board == 1 comparison is a constraint violation (use of equality operator between pointer and integer that isn't a null pointer constant) that is probably evaluating to the int value 0, and that int value 0 (which is not a null pointer constant here) is probably being converted in an implementation-defined way to a null pointer (which is another constraint violation due to lack of an explicit cast) of type char (*)[3] to become the value of the board parameter in the evaluateWinConditions function. The evaluateWinConditions function is dereferencing that null pointer, resulting in an access violation exception.
There are plenty of other errors in the original code.
