从键盘读入100个二位无符号数，将其按升序排列并显示输出

main()
{
int i;
unsigned a[100];
for (i=0;i<100;i++ )
scanf("%u",&a[i]);
px(a);
for (i=0;i<100;i++ )
printf("%3u",a[i]);

getch();
}
px(unsigned a[100])
{
int i,j;
unsigned t;

for (i=0;i<99;i++ )
for(j=0;j<99;j++)
if (a[j]>a[j+1]) {t=a[j];a[j]=a[j+1];a[j+1]=t;}

}

#include <iostream>
#include <algorithm>
using namespace std;

int main() {
int num[128], n = 100;
for (int i = 0; i < n; ;++i)
cin >> num[i];
sort(num, num + n);
for (int i = 0; i < n; ++i)
cout << num[i] << " ";
cout << endl;
return 0;
}

就如一楼那样...
