Change value to array for c++ and saving file

I'm trying to simply change a value to an array and then to write that array to a file and save it. Here is my code:

void changePrices(float prices[15])
{
    int row;
    string filename = "rowPrices.dat";
    ofstream inFile(filename);

    cout << "Enter in the row: ";
    cin >> row;
    int rownumber = row - 1;
    cout << "Enter in the new price: ";
    float price;
    cin >> price;
    cout << price << endl;
    price = prices[rownumber];
    for (int i = 0; i < rowvalue; i++)
    {
        inFile << prices[i] << endl;
    }
    cout << prices[rownumber];

    ifstream save(filename);
}

However, my price variable is not being written to the array value (in this case prices[rownumber]). I simply try to assign the floating variable to the array, but it simply is not being overwritten. Additionally, I want that file to be saved using some kind of save function. Is it working properly? How can I overwrite my variable to the array value? Note: the array is a float.

You're not changing the array, you are copying a value from the array to price, effectively overwriting what the user entered.

price = prices[rownumber];

should be

prices[rownumber] = price;
