求助！刚刚开始学习有个问题请帮忙
今天按照书上的程序输入进去可是怎么修改也无法运行，不知道哪里出错了，谁能帮一下，谢谢了
#include <iostream>
using namespace std;
const int DefaultSize = 10;
class Animal
{
public:
Animal(int);
Animal();
~Animal() {}
int GetWeight() const { return itsWeight; }
void Display() const { std::cout < < itsWeight; }
private:
int itsWeight;
};
Animal::Animal ( int weight):
itsWeight(weight)
{}
Animal::Animal():
itsWeight(0)
{}
template <class T>
class Array
{
public:
Array(int itsSize = DefaultSize);
Array(const Array &rhs);
~Array() { delete [] pType; }
Array& operator=(const Array&);
T& operator[](int offSet) { return pType[offSet]; }
const T& operator[](int offSet) const
{return pType[offSet]; }
int GetSize() const { return itsSize; }
template <class T>
friend ostream& operator < < (ostream&, Array <T> &);
private:
T *pType;
int itsSize;
};
template <class T>
ostream& operator < < (ostream& output, Array <T> & theArray)
{
for(int i=0; i <theArray.itsSize; i++)
output < < "[ " < < i < < "] " < < theArray[i] < < endl;
return output;
}
template <class T>
Array <T> ::Array(int size):
itsSize(size)
{
pType = new T[size];
for (int i=0; i <size; i++)
pType[i] =0;
}
template <class T>
Array <T> ::Array(const Array &rhs)
{
itsSize = rhs.GetSize();
pType = new T[itsSize];
for (int i=0; i <itsSize; i++)
pType[i] = rhs[i];
}
template <class T>
Array <T> & Array <T> ::operator=(const Array &rhs)
{
if (this == &rhs)
return *this;
delete [] pType;
itsSize = rhs.GetSize();
pType = new T[itsSize];
for (int i=0; i < itsSize; i++)
pType[i] = rhs[i];
return * this;
}
int main()
{
bool Stop = false;
int offset, value;
Array <int> theArray;
while (Stop == false)
{
cout < < "Enter an offset (0-9) ";
cout < < "and a value. (-1 to stop): ";
cin > > offset > > value;
if (offset <0)
break;
if (offset> 9)
{
cout < < "***Please use values between 0 and 9.***\n ";
continue;
}
theArray[offset] = value;
}
cout < < "\nHere 's the entire array:\n ";
cout < < theArray < < endl;
char response;
cin > > response;
return 0;
}
在１０８行处
就是cout < < theArray < < endl;这里编译器提示错误是
D:\C++\第三周\19.3.cpp(108) : error C2563: mismatch in formal parameter list
D:\C++\第三周\19.3.cpp(108) : error C2568: ' < < ' : unable to resolve function overload
could be 'class std::basic_ostream <unsigned short,struct std::char_traits <unsigned short> > &__cdecl std::endl(class std::basic_ostream <unsigned short,struct std::char_traits <unsigned short> > &) '

d:\microsoft visual studio\vc98\include\ostream(367) : see declaration of 'endl '
执行 cl.exe 时出错.
这个问题解决不了下边的知识都有类似的地方．．．所以希望大家帮忙解决，非常感谢！！
[解决办法]
vc8 直接编译过去,没有错误
[解决办法]
vc 6 的模板语法支持不大好.
好像将
template <class T>
ostream& operator < < (ostream& output, Array <T> & theArray)
内联在类里可以.
[解决办法]
vc8，就是vs2005，很大的，好几个G
不如用devcpp，对标准支持好点，vc6对标准支持不好

这样在vc6下就行了
