使用iomanip格式化矢量输出

Question

I'm having some trouble here. I have a file that looks like this (here's a snippet)

Sophia F 22158
Emma F 20791
Isabella F 18931
Jacob M 18899
Mason M 18856
Ethan M 17547

and I want to put each name, and the name's respective number into seperate vectors. For example, I would have 4 vectors: 1 for women's names and 1 for women's numbers, and the same for men's and men's numbers. (so 4 total)

I have this code, which will go through the file and pull out these elements and put them in vectors.

for (int i = 0; i < numTimes; i++) {
        getline (inputFile, inputLine);
        ss.str(inputLine); //ss is a string stream
        ss >> name >> gender >>  popularity;
        if (gender == 'M') {
            mNames[i] = name;
            mFrequency[i] = popularity;
        } else if (gender == 'F') {
            fNames[i] = name;
            fFrequency[i] = popularity;
        }

        ss.clear();

    }

and I use this method to print it out:

cout << counter << " Most Popular Baby Names" << endl << endl;
    cout << left << setw(15) << "Girls" ;
    cout << right << setw(9) << "Frequency" <<"      ";
    cout << left << setw(15) << "Boys";
    cout << right << setw(9) << "Frequency" << endl;
    for (int i = 0; i < counter; i ++) {
        cout << left << setw(15) << fNames[i] ;
        cout << right << setw(9) << fFreq[i] <<"      ";
        cout << left << setw(15) << mNames[i];
        cout << right << setw(9) << mFreq[i] << endl;
   {

but then I get this output: http://i.stack.imgur.com/2x0ta.png

But I would like for it to be like this: http://i.stack.imgur.com/OSIX9.png

So I'm thinking I either need to go through before I print and remove all the whitespace/0's in these vectors, or I need to check while I'm printing out. Does anyone have any pointers?

Solved, thanks guys.

I used two separate while loops, one for each set of arrays. In between them I reset the ifstream back to the beginning. This way, it goes through until each vector has 5 non-zero elements.
