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

Answer 1

#include 
#include 

const char *input = "1,1,1,1,2,1,1,1,0";

int main() {
    std::stringstream ss(input);
    std::vector output;
    int i;
    while (ss >> i) {
        output.push_back(i);
        ss.ignore(1);
    }
}

Bad input (for instance consecutive separators) will mess this up, but you did say simple.
