If I wanted to read in comma delineated data from an input file such as 1, 2, 3 INCLUDING the commas?


If you have boost-dev installed, then include header file <boost/algorithm/string.hpp>

void readInputRecord(std::ifstream
&inputFile,
std::vector<std::string>& fields) {
    std::string line;
    fields.clear();
    while (std::getline(inputFile, line)) {
            boost::split(fields, line,
boost::is_any_of(","));
            for
(std::vector<std::string>::iterator it =
fields.begin(); it != fields.end(); ++it)
                std::cout << *it <<
"#";

            std::cout << std::endl;
    }
}

The all fields are contained in the vector, include the empty field. The code is not tested, but should work.

The function in the .filter() is not working as I wanted
The function you pass to filter is supposed to have the type: Type: Function( Integer index, Element element ) => Boolean So it expects you to return true if the element is to be included in the filtered set rather than use a selector. You could use the index parameter to decide whether the element is odd: $("td").filter(function(index){ var isOdd = index % 2 === 1; return isOdd; }

MySQL will automatically cast the string numbers for you. SELECT SUM(replace(price, ',', '')) FROM sample.inventory DEMO However, you shouldn't store the numbers like this...
