    <p>I'm creating a simple tictactoe game in C. However I keep getting this error in my main function, I don't know what expected expression it wants before my else statement. How the program works is I get symbols from both players, an they begin the game.</p> <p><strong>Error:</strong></p> <pre><code>tictac.c: In function ‘main’: tictac.c:31: error: expected expression before ‘else’ tictac.c: At top level: tictac.c:49: warning: conflicting types for ‘print’ tictac.c:30: warning: previous implicit declaration of ‘print’ was here tictac.c:63: error: conflicting types for ‘check’ tictac.c:63: note: an argument type that has a default promotion can’t match an empty parameter name list declaration tictac.c:29: error: previous implicit declaration of ‘check’ was here tictac.c:89: warning: conflicting types for ‘move’ tictac.c:28: warning: previous implicit declaration of ‘move’ was here </code></pre> <p><strong>Code:</strong> </p> <pre><code>char board[3][3]; int main(void) { int first; char player1, player2; printf("Player 1: Choose your symbol: \n"); player1 = getchar(); printf("Player 2: Choose your symbol: \n"); player2 = getchar(); int i=0; int win; char turn; while(win == 0) { if((i%2) == 0) turn = player1; move(player1); win = check(player1); print(); else turn = player2; move(player2); i++; } if (i == 8) printf("its a tie"); else printf("the winner is %c", turn); return 0; } /*printing the board that takes in a placement int*/ void print(void) { int r; printf("\n"); for (r = 0; r &lt; 3; r++){ printf(" %c | %c | %c \n" , board[r][0], board[r][2], board[r][3]); if (r != 2) printf("___________\n"); } printf("\n"); return; } /*check to see if someone won*/ int check(char player) { int r, c; for ( r = 0 ; r &lt;3 ; r++) { if ((board[r][0] == player) &amp;&amp; (board[r][1] == player) &amp;&amp; (board[r][2] == player)) return 1; } for ( c = 0 ; c &lt;3 ; c++) { if ((board[0][c] == player) &amp;&amp; (board[1][c] == player) &amp;&amp; (board[2][c] == player)) return 1; } if((board[0][0] == player) &amp;&amp; (board[1][1] == player) &amp;&amp; (board[2][2] == player)) return 1; if((board[0][2] == player) &amp;&amp; (board[1][1] == player) &amp;&amp; (board[2][0] == player)) return 1; return 0; } void move(char player) { int place; printf("player1, enter placement: \n"); scanf("%d", &amp;place); if (place == 1) board[0][0] = player; else if (place == 2) board[0][1] = player; else if (place == 3) board[0][2] = player; else if (place == 4) board[1][0] = player; else if (place == 5) board[1][1] = player; else if (place == 6) board[1][2] = player; else if (place == 7) board[2][0] = player; else if (place == 8) board[2][1] = player; else if (place == 9) board[2][2] = player; } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
