C++实现：

void main(){int n;cin>>n;int n1;int nums[1001] = {0};for (int i=0;i<n;i++){cin>>n1;nums[n1] = 1;}for (int i=0;i<1001;i++){if(nums[i] ==1)cout<<i<<endl;}system("pause");}

方法2：

void main(){int n;cin>>n;int n1;vector<int> nList;for (int i=0;i<n;i++){cin>>n1;nList.push_back(n1);}sort(nList.begin(),nList.end());vector<int>::iterator v1 = unique(nList.begin(),nList.end());nList.erase(v1,nList.end());for (int i=0;i<nList.size();i++){cout<<nList[i]<<endl;}system("pause");}
