C++ split string by line

Question

I need to split string by line. I used to do in the following way:

int doSegment(char *sentence, int segNum)
{
assert(pSegmenter != NULL);
Logger &log =

This fairly inefficient way just loops through the string until it encounters an \n newline escape character. It then creates a substring and adds it to a vector.

std::vector Loader::StringToLines(std::string string)
{
    std::vector result;
    std::string temp;
    int markbegin = 0;
    int markend = 0;

    for (int i = 0; i < string.length(); ++i) {     
        if (string[i] == '\n') {
            markend = i;
            result.push_back(string.substr(markbegin, markend - markbegin));
            markbegin = (i + 1);
        }
    }
    return result;
}
