reading two vectors from file

Problem is described here. I tried to solve it using code that's below, but it's not working.

const char* filename = "test.txt";
ifstream file1(filename);
vector<int> v1;
vector<int> v2;
vector<int> res;

int number;
char c;

while(1){
    while(1){
        v1.push_back(number);
        file1.get(c);
        if (c==';') break;
    }

    while(1){
        v2.push_back(number);
        file1.get(c);
        if (c=='\n') break;
    }

    for (vector<int>::iterator it = v2.begin(); it!=v2.end(); it++)
        cout << *it << ',';
    cout << endl;
    file1.get(c);
    if (c==EOF) break;
    file1.unget();
}

There is a problem with reading end of line. Is c=='\n' right?
