c++编程题，用new建一动态一维数组

Question

c++编程题，用new建一动态一维数组，用rand()随机产生50个整数，输出这50个整数，输出其中位数，最大数，最小数

Answer 1

#include <iostream>
#include<time.h>
#include <stdlib.h>
#include <algorithm>
using namespace std;
bool cmp(int a,int b)
{
    return a < b;
}
int main()
{
    srand((unsigned)time(NULL));
    int *arr = new int[50];
    for(int i=0;i<50;i++)
        arr[i] = rand();
    sort(arr,(arr+50),cmp);
    for(int i=0;i<50;i++)
    {
        cout << arr[i];
        if(!((i+1)%10))
           cout << endl;
        else
            cout << " ";
    }
    cout << "中位数:" << (arr[24]+arr[25])/2 << endl;
    cout << "最大数:" << arr[0] << endl;
    cout << "最小数:" << arr[49] << endl;

    return 0;
}
