Answer 1

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int main()
{
int a[50];
int i;
int j;
int tmp;
FILE *fp;
srand(time(NULL));
for(i=0;i<50;i++)
{
a[i] = rand()%2001;
}
for(i=0;i<49;i++)
{
for(j=i+1;j<50;j++)
{
if(a[i]<a[j])
{
tmp = a[i];
a[i] = a[j];
a[j] = tmp;
}
}
}
fp = fopen("test.txt","w");
for(i=0;i<50;i++)
{
fprintf(fp,"%d\n",a[i]);
}
fclose(fp);
return 0;
}

Answer 2

#include <iostream>
#include <fstream>
#include <stdlib.h>
#include <queue>
using namespace std;

#ifdef VERIFY
#define out cout
#else
ofstream out("1.out");
#endif

int main()
{
int n;
priority_queue<int> q;
srand(2000);
for (int i = 1; i<=50; i++)
{
n = rand()%2001;
q.push(n);
}
while (!q.empty())
{
n = q.top();
q.pop();
out<<n<<endl;
}
return 0;
}
