Thread: Vector problem.

The other errors are actually from similar code; warnings are from comparing unsigned int to int. The function I am writing is to open a file at filename. This file might look something like this:

0 0 0 2 3 4 -1
0 0 3 4 5 -1
0 0 6 -1

I am just having issues pushing the int I read in into the vector. I am unsure why it is not working.

Code:

vector<vector<int> > Modifier_Levels;   //from the class' header

void Item_Gen::Load_Modifier_Tables(string filename)
{
    int input;
    ifstream in;
    in.open(filename.c_str());
    Modifier_Levels.push_back(vector<int>());     //add an empty row

    while(!in.eof())
    {
        in>>input;
        if(input != -1)Modifier_Levels.push_back(input);            //add a value to the current modifier level
        else if(!in.eof())Modifier_Levels.push_back(vector<int>());   //if there is still another level to read in add a line for it.
    }
}

I thought a general push_back(int) pushes an int to the deepest vector in the system?

Alright then. Seems to have made it compile gotta go throw data at it and see if it behaves. Thanks.
