我想知道下面这个程序为啥错了,怎样修改!!!
#include <iostream>
using namespace std;
class MyTest
{
public:
int *number;
int count;
MyTest()
{
number=new int[20];
count=0;
}
void AddTail(int num)
{
number[count]=num;
count++;
}
friend ostream & operator << (ostream &os, const MyTest &my);
};
ostream & operator << (ostream &os, const MyTest &my)
{
for (int i=0;i<20;i++)
{
os<<my.number[i]<<" "<<endl;
}
return os;
}
class Second
{
public:
static MyTest test;
Second()
{
}
void OP()
{
for (int i=0;i<20;i++)
{
test.AddTail(i);
}
cout<<test;
}
};
void main()
{
Second sec;
sec.OP();
}
#include <iostream>
using namespace std;
class MyTest
{
public:
int *number;
int count;
MyTest()
{
number=new int[20];
count=0;
}
void AddTail(int num)
{
number[count]=num;
count++;
}
friend ostream & operator << (ostream &os, const MyTest &my);
};
ostream & operator << (ostream &os, const MyTest &my)
{
for (int i=0;i<20;i++)
{
os<<my.number[i]<<" "<<endl;
}
return os;
}
class Second
{
public:
static MyTest test;
Second()
{
}
void OP()
{
for (int i=0;i<20;i++)
{
test.AddTail(i);
}
cout<<test;
}
};
void main()
{
Second sec;
sec.OP();
}
class Second
{
public:
static MyTest test;
Second()
{
}
void OP()
{
for (int i=0;i<20;i++)
{
test.AddTail(i);
}
cout<<test;
}
};
不要把MyTest test定义成static 要不就不要再类里访问static成员的函数
1.第一行包含头文件,把扩展名写上吧
#include <iostream.h>
2.把static去掉
3.干嘛定义个namespace?然后后面也不用,删了吧
然后运行就没问题了
静态类出问题了,static去掉就可以了
