I created a Tic-Tac-Toe program in about 250 lines. How can I shorten this code?

I'm new to C programming and I recently challenged myself to writing a tic-tac-toe program. I found that my code becomes lengthy very quickly with so many if statements. This code works as is (and I still wish to add more features), I just think there's probably a more neat/efficient way to program this. Any ideas on how to trim this up?

#include <stdio.h>
#include <stdlib.h>

typedef int bool;
#define true 1
#define false 0

int main()
{
    playGame();
    return 0;
}
int playGame()
{

    char scanned[3];
    printf("Do you wish to play tick-tack-toe?\n");
    scanf("%s", scanned);
    if(strcasecmp(scanned,"yes")==0)
        startGame();

    else
    {
        if (strcmp(scanned,"no")==0 || strcmp(scanned,"nah")==0 || strcmp(scanned,"naw")==0)
        {
            printf("That's too bad!/nThis program will now end.");
            return 1;
        }
        printf("Not valid input!/nThis program will now end.");
        return 1;
    }
}
int startGame()
{
    //Sets up board for values 1-9;
    char board[3][3] =
    {
        {'1','2','3'},
        {'4','5','6'},
        {'7','8','9'}
    };

    bool winner = false;
    printf("\n\nHere is your playing board. Player One is Os and Player Two is Xs\n");
    printf("Entering a number 1-9 (then pushing enter) as shown below will use\nthe current Player's turn in that location.\n");


    printf("\n\n");
    printf(" %c | %c | %c\n", board[0][0], board[0][1], board[0][2]);
