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

Answer 1

Simple Copy/Paste function, based on the boost tokenizer.

void strToIntArray(std::string string, int* array, int array_len) {
  boost::tokenizer<> tok(string);
  int i = 0;
  for(boost::tokenizer<>::iterator beg=tok.begin(); beg!=tok.end();++beg){
    if(i < array_len)
      array[i] = atoi(beg->c_str());
    i++;
}
