Replace part of a string with another string

Question

Is it possible in C++ to replace part of a string with another string?

Basically, I would like to do this:

QString string(\"hello $name\");
string.re         


        

Answer 1

This could be even better to use

void replace(string& input, const string& from, const string& to)
{
    while(true)
    {
        size_t startPosition = input.find(from);
        if(startPosition == string::npos)
            break;
        input.replace(startPosition, from.length(), to);
    }
}
