According to syntax postfix increment returns copy of unmodified variable (C++ == C), while prefix increment returns incremented variable (++C == C + 1).

    ???

    If c = 1, then c++ = 2

    #include <iostream> using namespace std;

    int main() {

    int i = 10;

    cout << i++ << endl;

    cout << i << endl;

    }

    postfix ++ increments the variable.

        Yes c++ == c. That’s the point Bjarne Stroustrup made. It is the C language but then it’s better.

        Nowadays they’re not completely compatible. But originally it was a preprocessor that created the C equivalent to be compiled. You could write C++ that compiled with a C compiler as long as you didn’t use the extra features.

          Yeah.

          Perhaps ++C == Java or something.

          I’m sure that’s offensive to some, so apologies for airing the thought.
