c++ - reading from file to vector- last line gets repeated

I am trying to read values from a file to a vector

std::vector setTimesArray (std::string flName){
    int i=0, dummy=0;
    float temp;
    std::vector pObs;
    std::string line;
    std::ifstream inFile;
    inFile.open(flName.c_str());
    if(!inFile){
        std::cout<<"\n.obs file not valid. Quitting programme...";
        exit(1);

    }
    while(inFile.good()){
        i++;
        getline(inFile, line);
        if(i>=3){ //I don't want first two lines
            std::istringstream in(line);
            in>>dummy;//discards first value in the line
            in>>temp;
            pObs.push_back(temp);
            in.str(""); //discards remaining part of the line

        }        

    }
    return pObs;
    inFile.close();    
}

Problem is, the last value gets repeated. For example, flName had total 975 lines. Thus pObs must be having size=973 (975-2 initial lines). But the size is 974 and I see that the last value is repeating. What mistake have I made?
