Question

I want to replace the string text=s_o_m_e=text with text=s-o-m-e=text

I have a starting and ending index:

std::string str("text=s_o_m_e=text");

std::string::size_type start = str.find("text="), end;

if (start != std::string::npos) {
    end = str.find("=", start);

    if (end != std::string::npos) {
        //...
    }
}

So, I’m looking for a function like this:

replaceAll(string, start, end, '_', '-');

UP:

std::replace(str.begin() + start, str.begin() + end, '_', '-');

Thanks, Blastfurnace

There is a function in <algorithm> for that.

std::replace(str.begin(), str.end(), '_', '-');
