Sorting my file of strings into my vector thinks I am trying to put characters in it?

When trying to use fstream to enter csv data into my program I am having an odd problem using a vector but it works fine with a random-sized array. I am not sure why but the error I am getting from visual studio is that there is no suitable conversion from string to char even though my vector is for strings. I am not sure if this is happening because of some weird case where it is trying to push back something I didn’t intend even though I double-checked it by putting outputs to see where it was happening.

==== Function ====
ifstream dataEve;
dataEve.open(fileName, std::ifstream::in);

std::vector<std::vector<string>> dataStore;
//string dataStore[10][10];                  ***works if you replace the vector above***

string currentLine;
string currentObject;
int x = 0;
int y = 0;

while (!dataEve.eof()) {
    getline(dataEve, currentLine, '\n');
    stringstream ss(currentLine);
    string currentLine;
    while (std::getline(ss, currentObject, ',')) {
        dataStore[x][y].push_back(currentObject);
        //dataStore[x][y] = currentObject;        ***works fine if you use this too***
        std::cout << currentObject << "\t";
        y++;
    }
    x++;
    std::cout << "\n";
}
std::cout << "\n\n";

dataEve.close();

==== fileName.csv ====
Organism,Genetic Code
Felis catus,ACTG
Canis lupis,ATCG

>Solution :

Like this

dataStore.push_back(std::vector<string>()); // add a new 'row'
while (std::getline(ss, currentObject, ',')) {
    dataStore.back().push_back(currentObject); // push the string onto the last 'row'
    std::cout << currentObject << "\t";
    y++;
}
x++;

As you can see from this code you don’t actually need the x and y variables, but I left them in anyway.

Two errors in your code, firstly dataStore[x][y] doesn’t exist as the vector has zero size, so that would be a run time error.

Secondly dataStore[x][y] is a string, so if you push_back on a string the compiler expects you to give a char. That’s the reason for the compiler error.
