Parsing a comma-delimited std::string [duplicate]

Answer 1

Input one number at a time, and check whether the following character is ,. If so, discard it.

#include 
#include 
#include 
#include 

int main()
{
    std::string str = "1,2,3,4,5,6";
    std::vector vect;

    std::stringstream ss(str);

    for (int i; ss >> i;) {
        vect.push_back(i);    
        if (ss.peek() == ',')
            ss.ignore();
    }

    for (std::size_t i = 0; i < vect.size(); i++)
        std::cout << vect[i] << std::endl;
}
