#include<iostream>
using namespace std;
int main(){
double a[100];
int i=0,j=0;
int N,x;
const int P='999';//想要实现特定结束符，不去输入数字个数作为结束依据。
cout<<"请输入数字"<<endl;
cin>>x;
while(x!=P){
a[i]=x;
i++;
}
N=i; //输入部分有问题
for(i=0;i<N-1;i++){
for(j=0;j<N-1-i;j++){
int tmp;
if(a[j]>a[j+1]){
tmp=a[j];
a[j]=a[j+1];
a[j+1]=tmp;
}
}
}
for(i=0;i<N;i++){
cout<<a[i]<<" ";
}
cout<<endl;
return 0;
