1. int * p;　　Represents the address of a variable of type int with p as the variable name; such as: int i = 3;　　p = &i; &i represents the address of IA. P holds the address of IB. P is not i,i nor p, modifying the value of P does not affect I, and

Suppose we have Class A, Class B, and class test, the class test has all the properties of Class A and Class B, and they all have the Temp property, and now we need to implement the set and read of the Temp property in class test, so write the
