Is there ever a need for a “do {…} while ( )” loop?

Question

Bjarne Stroustrup (C++ creator) once said that he avoids \"do/while\" loops, and prefers to write the code in terms of a \"while\" loop instead. [See quote below.]

Answer 1

consider something like this:

int SumOfString(char* s)
{
    int res = 0;
    do
    {
        res += *s;
        ++s;
    } while (*s != '\0');
}

It so happens that '\0' is 0, but I hope you get the point.
