设有基类定义:class Cbase{private:int a;protected. int b;public:int c;};派生类采用何种继承

写出程序的输出结果class Class1 { private string str = "Class1.str"; private int i = 0;

写出程序的输出结果class Class1 { private string str = "Class1.str"; private int i = 0;

写出程序的输出结果class Class1 { private string str = "Class1.str"; private int i = 0;

写出程序的输出结果class Class1 { private string str = "Class1.str"; private int i = 0;

对于下面定义的类A在函数f()中将对象成员n的值修改为60的语句应该是( ) class A { public: A(int x){n=x;} void SetNum(int n1){n=n1;} private: int n; } int f() { A*ptr=new A(6); }

如下代码定义了一个类Test:class Test {private int y;Test (int x) { y:x; }}现在为Test 类生成
