How to find and replace all occurrences of a substring in a string?

Question

I need to search a string and edit the formatting of it.

So far I can replace the first occurrence of the string, but I am unable to do so with the next occurrences

Answer 1

If ever the strings you need to invert are not of the same size:

void            Replace::replace(std::string & str, std::string const & s1, std::string const & s2)
{
    size_t      pos;

    pos = 0;
    while ((pos = str.find(s1, pos)) != std::string::npos)
    {
        str.erase(pos, s1.length());
        str.insert(pos, s2);
        pos += s2.length();
    }
    return ;
}
