Question

C++代码运行不了，谁来帮帮我？

#include <iostream.h>
#include <string.h>
template<class T>
void swap(T *const ptr1, T *const ptr2)
{
T temp=*ptrl;
*ptr1=*ptr2;
*ptr2=temp;
}
template<class T>
void bubbleSort(T*const array,int size)
{
int j;
for(int pass1;pass<size;pass++)
for(j=0;j<size-pass;j++)
if(array[j]>array[j+1])
swap(&array[j],&array[j+1]);
}
void main()
{
const int arraysize=10;
int a[arraysize]={10,9,8,7,6,5,4,3,2,1},i;
cout<<"integer date items in original order:"<<endl;
for(i=0;i<arraysize;i++)
cout<<" "<<a[i];
bubblesort(a,arraysize);
cout<<endl<<"integer date items in ascending order:"<<endl;
for(i=0;i<arraysize;i++)
cout<<" "<<a[i];
cout<<endl;
double b[arraysize]={10,10,9,9,8,8,7,7,6,6,5,5,4,4,3,3,2,2,1,1};
cout<<"Floating date items in original order:"<<endl;
for(i=0;i<arraysize;i++)
cout<<" "<<b[i];
bubblesort(b,arraysize);
cout<<endl<<"Floating date items in ascending order:"<<endl;
for(i=0;i<arraysize;i++)
cout<<" "<<b[i];
cout<<endl;

}

只要答案就行了。谢谢

帮你改好了，可以正确运行了，你对照着看吧。有好几次有错误的。
#include <iostream.h>
#include <string.h>
template<class T>
void swap(T *const ptr1, T *const ptr2)
{
T temp=*ptr1;
*ptr1=*ptr2;
*ptr2=temp;
}
template<class T>
void bubbleSort(T*const arr,int size)
{
int j;
for(int pass1=0;pass1<size;pass1++)
for(j=0;j<size-pass1-1;j++)
if(arr[j]>arr[j+1])
swap(&arr[j],&arr[j+1]);
}

void main()
{
const int arraysize=10;
int a[arraysize]={10,9,8,7,6,5,4,3,2,1},i;
cout<<"integer date items in original order:"<<endl;
for(i=0;i<arraysize;i++)
cout<<" "<<a[i];

bubbleSort(a,arraysize);
cout<<endl<<"integer date items in ascending order:"<<endl;
for(i=0;i<arraysize;i++)
cout<<" "<<a[i];
cout<<endl;

double b[arraysize]={10,9,8,7,6,5,4,3,2,1};
cout<<"Floating date items in original order:"<<endl;
for(i=0;i<arraysize;i++)
cout<<" "<<b[i];
bubbleSort(b,arraysize);
cout<<endl<<"Floating date items in ascending order:"<<endl;
for(i=0;i<arraysize;i++)
cout<<" "<<b[i];
cout<<endl;

}

追问

谢谢了。抱歉没法加分了。
