Whats wrong - TicTacTo

What's wrong with the this first part of a game.
It everytime says Falsche Ausgabe

Code:

---


#include <iostream>


using namespace std;
char f_1 = '1';
char f_2 = '2';
char f_3 = '3';
char f_4 = '4';
char f_5 = '5';
char f_6 = '6';
char f_7 = '7';
char f_8 = '8';
char f_9 = '9';
bool bGameover=false;
char eingabe;
char player_turn = '1';
int Schleife = 1;
















int main (void)
{


do
{
   
  //Spielfeld
    cout << "==============" <<endl; 
    cout << " | ";
    cout << f_1;
    cout << " | ";
    cout << f_2;
    cout << " | ";
    cout << f_3;
    cout << " |  " << endl;
    cout << "==============" <<endl;
    cout << " | ";
    cout << f_4;
    cout << " | ";
    cout << f_5;
    cout << " | ";
    cout << f_6;
    cout << " | " << endl;
    cout << "==============" <<endl;
    cout << " | ";
    cout << f_7;
    cout << " | ";
    cout << f_8;
    cout << " | ";
    cout << f_9;
    cout << " | " << endl;
    cout << "==============" << endl;
    cout << "W?hlen sie ein Feld: ";
    cin >> eingabe;
 
            if (eingabe == 1 && f_1 == 1 ) {
            f_1= 'x';
            } else if (eingabe == 2 && f_2 == '2') {
            f_2= 'x';
            } else if (eingabe == 3 && f_3 == '3') {
                f_3= 'x';
            } else if (eingabe == 4 && f_4 == '4' ) {
                f_4= 'x';
            } else if (eingabe == 5 && f_5 == '5' ) {
                f_5= 'x';
            } else if (eingabe == 6 && f_6 == '6') {
                f_6= 'x';
            } else if (eingabe == 7 && f_7 == '7') {
                f_7= 'x';
            } else if (eingabe == 8 && f_8 == '8') {
                f_8= 'x';
            } else if (eingabe == 9 && f_9 == '9') {
                  f_9= 'x';
            } else {
                cout << "Falsche Eingabe" <<endl;
               
            }
                 
 
 
   


}
while(!bGameover); 
 
 


  cin.sync();
  cin.get();
  return 0;
}

You have declared eingabe as a char but you are trying to compare this character to an int value in your if statements. Also you should move your variable declarations into main(). Using global variables is a bad practice, learn to declare your variables within the smallest scope possible.
