看程序写结果
#include<iostream.h>
class test
{public;
test();
test(int);
~test();
void display();
protected;
int n;
};
test::test(){cout<<"Constructing normally\n";}
test::test(int num)
{n=num;
cout<<"Constructing with a number:"<<n<<endl;}
void test::display() {cout<<"Display a numbe:"<<n<<endl;}
test::~test(){cout<<"Destructing"<<endl;}
void main()
{test obj1;
test obj2(59);
obj1.display();
obj2.display();
}
#include<iostream.h>
class test
{public;
test();
test(int);
~test();
void display();
protected;
int n;
};
test::test(){cout<<"Constructing normally\n";}
test::test(int num)
{n=num;
cout<<"Constructing with a number:"<<n<<endl;}
void test::display() {cout<<"Display a numbe:"<<n<<endl;}
test::~test(){cout<<"Destructing"<<endl;}
void main()
{test obj1;
test obj2(59);
obj1.display();
obj2.display();
}
首先将public和protect后面的";"":"。
之后运行结果：（由于obj1的n没有显式初始化也没有赋值，因此调用obj1.display()时，打印出-858993460，这是在Debug模式编译下的产物，如果是在Release版该数字则随机产生。）
Constructing normally
Constructing with a number
Display a numbe:-858993460
Display a numbe:59
Destructing
Destructing
