Searching data from .txt file in c++

I am working on my project and stuck on this point.

I am writing my data in Heavy Bike.txt file and everything works perfectly except the searching feature, I am searching the details of bike with respect to its color that user enter.

For Example : When user enter color Black the black coloured bikes in the .txt file should display on console

Problem : When I enter the color then my program is not displaying the correct information

The data I entered the .txt file are like this

234
543
Black
Heavy Bike
2020

123
943
Red
Heavy Bike
2019

These are details of 2 Bikes

But the output I got is this

Enter Color of Bike you want :  Black

Found
0                       //registration number
943                    // id
Red                   // color
Heavy Bike           // bike type
2019                //model

I enter the color black but it is showing the red color bike details. In addition, it is showing the registration number 0

Here is my code so far

Writing data to the text file

void writingDet()
{
    ofstream file;
    if (bike_typ == "Heavy Bike")
    {
        file.open("Heavy Bike.txt", ios::app);
        if (file.is_open())
        {
            file << reg_no << endl;
            file << id << endl;
            file << Bike_clr << endl;
            file << bike_typ << endl;
            file << model << endl;
            file << endl;
        }
        else
        {
            cerr << "Your File cannot be open" << endl;
        }
    }file.close();
}

Search Function

int search(string clr)
{
    string line;
    ifstream fm;
    fm.open("Heavy Bike.txt");
    for (line; getline(fm, line);)
    {

        if (line.find(clr) != string::npos)
        {
            cout << "\n\nFound" << endl;
            fm >> reg_no;
            cout << reg_no << endl;
            fm >> id;
            cout << id << endl;
            getline(fm, Bike_clr);
            cout << Bike_clr << endl;
            getline(fm, bike_typ);
            cout << bike_typ << endl;
            fm >> model;
            cout << model << endl;
        }
    }
    return 1;
}

input data function

void inputData()
    {
        cout << endl;
        cout << "Enter registration no of Car : " << ' ';
        cin >> reg_no;
        cout << "Enter ID of Car : " << ' ';
        cin >> id;
        cin.ignore();
        cout << "Enter Car Color : " << ' ';
        getline(cin, car_clr);
        cout << "Enter Car Type : " << ' ';
        getline(cin, car_typ);
        cout << "Enter Model (year) : " << ' ';
        cin >> crmodel;
        cin.ignore();
        cout << endl;
        cout << endl;
    }

main

int main()
{
    Vehical* vc[5];
    Bike bk;
    string clr;
    bool found;
    for (int i = 0; i < 2; i++)
    {
        vc[i] = new Bike;
        vc[i] = &bk;
        vc[i]->inputData();
        vc[i]->writingDet();
    }
    cin.ignore();
    cout << "\nEnter Color of Bike you want : " << ' ';
    getline(cin, clr);
    for (int k = 0; k < 2; k++)
    {
        found = vc[k]->search(clr);
        if (found)
        {
            break;
        }
        else
        {
            continue;
        }
    }
    cout << endl;
    system("PAUSE");
    return 0;
}

In short, when I input specific color then that colored bike details in .txt file should display. Thanks you so much .

PS. I am using abstract class in my program and here is the complete code https://ideone.com/flXnOU
