输出数字大小排列的结果，数字间没有分隔开

#include<iostream>
#include<algorithm>
using namespace std;
int main()
{
    int a[10],i;
    cout << "input 10 numbers:" << endl;
    for (i = 0; i < 10; i++)
    {
        cin >> a[i];
    }
    sort(a, a + 10);
    cout << "the sort numbers:" << endl;
    for (i = 0; i < 10; i++)
    {
        cout << a[i];
        cout << ' ';//''中间是空格
    }
    return 0;
}
