要求在堆空间分配5个整型变量空间，分别存放100,200,300,400,500，要求把这个五个数倒序输出，即输出500,400,300,200,100。（要求使用new和delete操作符分配和回收堆空间）下面程序错那了？

Question

#include
int main()
{
int arraysize,t,j;
int *array;
cout<<"please input a number of array elements:\n";
cin>>arraysize;
if((array=new int[arraysize])==NULL)
{
cout<<"can't allocate more memory,terminating.\n";
exit(1);
}
for(int count=0;count array[count]=count+100;
for(int i=0;i {
for(int j=0;j {
if(array[j]>array[j+1])
{
t=array[j];
array[j]=array[j+1];
array[j+1]=t;
}
}
}
cout<<array[j]<<" "<<endl;
delete[]array;
return 0;
}

Answer 1

for(int count=0;count array[count]=count+100;
for(int i=0;i {
for(int j=0;j {
这里都不对

完整给你写一个

#include <iostream>
using namespace std;
int main()
{
int n;
cin >> n;
int * arr = new int[n];
if (!arr)
{
cout << "error on alloc";
return;
}
for (int i = 0; i < n; i++) cin >> arr[i];
for (int i = n - 1; i >= 0; i--) cout << arr[i] << " ";
delete[] arr;
return 0;
}
