动态申请空间malloc

#include<iostream>
#include<fstream>
#include<stdlib.h>  //重要！！
using namespace std;

int main(void)
{
    cout<<"请输入一个正整数n"<<endl;
    int n;
    cin>>n;

    freopen("a.in","r",stdin);
    freopen("a.out","w",stdout);
    int *m = (int*)malloc(n*sizeof(int));   
//重要！！虽然是C，但是感觉比new之类的简洁好多，喜欢^^
    for (int i=0;i<n;i++)
    {
        cin>>m[i];
    }
    int k;
    cin>>k;
    for (int j=0;j<n;j++)
    {
        if (m[j]>k)
            cout<<m[j]<<" ";
    }
    fclose(stdin);
    fclose(stdout);
    return 0;
}
