Counter skipped by case error

[amglavin]

Every time I try to run my program I get and error that says "initialization of 'counter' is skipped by 'case' label" in line 113. I don't understand how to fix it.

Encase case part in block:

case 2:
{
    int counter = 0;
    while(counter < 301)
        cout << "Enter the number of miles." << endl;
    cin >> miles;
    kilometers = miles * 1.61;
    ofs << miles << "=" << kilometers << endl;
    counter++;
    break;
}

(Your code here has bug BTW. I hope proper identation will help you to locate it.)
