My code prints a different number when I use fout instead cout

Hey so i was doing this excercise and i figured out that when you use fout instead of cout it prints a different number when you have to print the thing i higlihted in the code example if you put in

14 -783 421 693

-153 680 443 741

as an imput

it will cout 595441

and it will fout 0595441

 #include <bits/stdc++.h>
    using namespace std;
    int main() {
      ifstream fin("billboard.in");
      ofstream fout("billboard.out");
    int x1,y1,x2,y2,px1,py1,px2,py2;

    fin>>x1>>y1>>x2>>y2>>px1>>py1>>px2>>py2;

    x1+=1000;
    x2+=1000;
    y1+=1000;
    y2+=1000;
    px1+=1000;
    px2+=1000;
    py1+=1000;
    py2+=1000;

    int a1=(x2-x1)*(y2-y1);

    if(x2<=px2&&x1>=px1&&y2<=py2&&y1>=py1){
    fout<<0;
    }

    else if(x2<=px2&&x1>=px1){
    if(py2>=y2){
      fout<<0;
    }
     if((py2<=y1)|(py1>y1&&py2<y2) ){
    fout<<a1;
    }else{
    int ma=max(py1,y1);
    int mi=min(py2,y2);
    fout<<((x2-x1)*(y2-y1))-((x2-x1)*(mi-ma));
    cout<<((x2-x1)*(y2-y1))-((x2-x1)*(mi-ma)); /********************************************************/
    }
    }


    else if(y2<=py2&&y1>=py1){

     if(px2<=x1|px1>x1){
    fout<<a1;
    }else{
    int ma=max(px1,x1);
    fout<<((y2-y1)*(x2-x1))-((y2-y1)*(px2-ma));
    }
    }


    else{
      fout<<a1;
    }

    return 0;
    }
