C++ should be called ++C

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.
Postfix increments variable too, but as a side effect. in your code
cout << i++ << endl;
prints 10 which means, that i++ returned copy of unincremented i.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.
