Question

fatal error C1083: Cannot open include file: 'iostream.h': No such file or directory这个错误怎么改

#include <iostream.h>

using namespace std;

template<typename DataType>
class QuickSortTemp
{
public:
QuickSortTemp()
{
}

~QuickSortTemp()
{
}

public:

static void QuickSort(DataType* Array, int nLower, int nUpper)
{

if (nLower < nUpper)
{
int nSplit = Partition (Array, nLower, nUpper);//数据切分为两个部分
QuickSort (Array, nLower, nSplit - 1);//左半部分递归排序
QuickSort (Array, nSplit + 1, nUpper);//右半部分递归排序
}
}

static int Partition (DataType* Array, int nLower, int nUpper)
{
int nLeft = nLower + 1;
DataType Pivot = Array[nLower];

int nRight = nUpper;

DataType Swap;
while (nLeft <= nRight)
{
while (nLeft <= nRight && Array[nLeft].CompareTo(Pivot) <= 0)
nLeft = nLeft + 1;
while (nLeft <= nRight && Array[nRight].CompareTo(Pivot) > 0)
nRight = nRight - 1;

if (nLeft < nRight)
{
Swap = Array[nLeft];
Array[nLeft] = Array[nRight];
Array[nRight] = Swap;
nLeft = nLeft + 1;
nRight = nRight - 1;
}
}

Swap = Array[nLower];
Array[nLower] = Array[nRight];
Array[nRight] = Swap;
return nRight;
}
};

struct MyPoint
{
MyPoint()
{
}

MyPoint(int x, int y)
{
this->x = x;
this->y = y;
}

int CompareTo(MyPoint& b)
{
if(this->x < b.x)
return -1;
else if(this->x > b.x)
return 1;
else
{
if(this->y > b.y)
return 1;
else if(this->y < b.y)
return -1;
else
return 0;
}
}

int x;
int y;
};
int i;
int _tmain(int argc, int * argv[], int * envp[])
{
int nRetCode = 0;

//Point数组
MyPoint points[10] = {MyPoint(1,1), MyPoint(2,5), MyPoint(7,11), MyPoint(100,2),
MyPoint(1, 7), MyPoint(9,32), MyPoint(7, 1), MyPoint(2,2),
MyPoint(1,1), MyPoint(9,5)};
int count = 10;

//排序前
cout<<"before quicksort"<<endl;
for(int i = 0 ; i <count ; i ++)
cout<< points[i].x<< points[i].y<<endl;

//调用模板类排序
QuickSortTemp<MyPoint>::QuickSort(points, 0, count - 1);

//排序后
cout<<"after quicksort"<<endl;
for(i = 0 ; i <count ; i ++)
cout<< points[i].x<< points[i].y<<endl;
return nRetCode;
}
这个程序的错误怎么改我真的很急啊各位帮帮忙

Answer 1

#include <iostream.h>
using namespace std;
改为：
#include <iostream> //这里!这里!这里!这里!这里!这里!
using namespace std;

追问

不是吧

追答

要么就用：
#include

要么就用：
#include
using namespace std;

这么用是错的：
#include
using namespace std;
