This code snippet extracts the tokens using a single loop.

#include 
#include 
#include 

int main(int argc, char **argv) {

    if(argc != 2) {
        return(1);
    }

    std::string file = argv[1];
    std::ifstream fin(file.c_str());

    char i;
    int j, k;
    std::string line;
    std::istringstream iss;
    while (std::getline(fin, line)) {
        iss.clear();
        iss.str(line);
        iss >> i >> j >> k;
        std::cout << "i=" << i << ",j=" << j << ",k=" << k << std::endl;
    }
    fin.close();
    return(0);
}
