closing while(cin.good()) loop properly

I'm trying to make the program exit properly without it. I have '|' as my exit, if its the first thing I do when first running, it closes fine. But after entering values and printing them, afterwards entering '|' to exit. It prints out: "The smaller value is 0 The larger is previous second value" // want to remove this from showing

int main()
{    
double first = 0, second = 0;
while(cin.good()){
    char exit;
    cout << "Enter '|' to exit.\n";
    cout << "Enter two numbers:";
    cin >> first >> second;
    exit = cin.peek();

    if(exit=='|'){
        break;}
    else{
        if(first<second){
            cout << "\nThe smaller value is " << first << "\nThe larger value is " << second << endl;
        }
        else if(first>second){
            cout << "\nThe smaller value is " << second << "\nThe larger value is " << first << endl;
        }
    }
  }
}
