为什么不能排序

// ConsoleApplication1.cpp : 定义控制台应用程序的入口点。
//主函数

#include "stdafx.h"
#include<iostream>
#include"function1.h"
using namespace std;
//写一个大-->小排列的程序
int main()
{

int unknown_number[10];
for (int i = 0; i < 10; i++) {
cout << "please enter number";
cin>> unknown_number[i];
}
cout << sizeof(unknown_number);
int a;

a = autosorting(unknown_number);

return 0;



//头文件function1
#include<iostream>
using namespace std;
//排序函数
int autosorting(int unsorting_number[]) {

}
}
}
