what's an expression and expression statement in c++?

Question

I\'ve read that usually statements in c++ end with a semi-colon; so that might help explain what an expression statement would be. But then what would you call an expression

Answer 1

An expression is part of a statement, OR a statement itself.

int x; is a statement and expression.
