C++ Writing a column of a CSV file into a vector

I have a CSV file with a bunch of columns, but I only need the information for the 11th column. How do I read through each line and skip to the 11th column in each line? I'm struggling to find clear information on how to read files in c++. This is what I have so far:

std::string readStock(std::string fileName){
   std::vector<double> ticker; //create vector
   std::ifstream f(fileName, std::ios::in|std::ios:: binary|std::ios::ate);
   if(f.is_open()){
     std::string str;
     getline(f,str);              //skip the first row
     while(getline(f,str)){       //goes through each like
       std::istringstream iss(str);
       std::string skip;
       for(int i=1;i<=11;++i){    //skips until we get to the column that we want        
        std::getline(f,skip, ','))
     }
