Question

C++正在考试改错题 在线等答案 急!!

一、 改错
1．
#include <iostream.h>
class MyClass
{ public:

MyClass(int i){member=i;}
void SetMember(int m){member=m;}
int GetMember()const{return menber;}
void print()cont{cout<<"member="< }
private:
int member;
};
voed main()
{
/* * * * * * * * * * found * * * * * * * * * */
MyClass obj1;
obj1.print();
MyClass obj2(3);
/* * * * * * * * * * found * * * * * * * * * */
obj1.member=5;
/* * * * * * * * * * found * * * * * * * * * */
MyClass.SetMember(10);
obj1.print();
obj2.print();
}
2．
#include <iostream.h>
class A
{
public:
A(char *s) { cout << s << endl; }
~A() {}
};
class B:public A
{
public:
B(char *sl,char *s2) :A(sl)
{
cout << s2 << endl;
}
};
class C:public A
{
public:
C(char *sl,char *s2) :A(sl)
{
cout << s2 << endl;
}
};
class D:public B,public C
{
public:
D(char *sl,char *s2,char *s3,char *s4) :B(sl,s2),C(sl,s3)
{
cout << s4 << endl;
} ;
void main ()
{
D d("class A","class B","class C","class D");
cout<<"welcome to you"<<endl;
system("pause");

}
能运行成功就性了

Answer 1

#include <iostream>
using namespace std;
class MyClass
{ public:
MyClass(int i=0){member=i;}//带默认值的构造函数
void SetMember(int m){member=m;}
int GetMember()const{return member;}
void print()const{cout<<"member="<<member<<endl; }
private:
int member;
};
void main()
{
/* * * * * * * * * * found * * * * * * * * * */
MyClass obj1;
obj1.print();
MyClass obj2(3);
/* * * * * * * * * * found * * * * * * * * * */
obj1.SetMember(5);
/* * * * * * * * * * found * * * * * * * * * */
obj2.SetMember(10);
obj1.print();
obj2.print();
}

------------------------------------------
#include <iostream>
using namespace std;
class A
{
public:
A(char *s) { cout << s << endl; }
~A() {}
};
class B:public A
{
public:
B(char *sl,char *s2) :A(sl)
{
cout << s2 << endl;
}
};
class C:public A
{
public:
C(char *sl,char *s2) :A(sl)
{
cout << s2 << endl;
}
};
class D:public B,public C
{
public:
D(char *sl,char *s2,char *s3,char *s4) :B(sl,s2),C(sl,s3)
{
cout << s4 << endl;
}
};
void main ()
{
D d("class A","class B","class C","class D");
cout<<"welcome to you"<<endl;
system("pause");
}
