First the definition of a++ and ++a: Look at an examplea:a=5; B=++a;  equivalent to A=a+1;b=a; The result is a=6,b=6.b:a=5; b=a++; equivalent to b=a;a=a+1; The result is a=6,b=5.So the book has:(1) If a variable is increased by 1 (minus 1) with the

1. Left and right valuesAn lvalue is a persisted object that persists after an expression ends, and an rvalue is a temporary object that no longer exists at the end of an expression. In C++11, the right value is divided into two types: the Dead
