文件中有一组整数，要求排序后输出到另一个文件中

#include<iostream>#include<fstream>#include<vector>using namespace std;
void order(vector<int>& data);
int main(){ vector<int> data; ifstream in("d:\\test.txt"); if(!in) { cerr<<"文件不能打开"<<endl; abort(); } int temp; while(!in.eof()) { in>>temp; data.push_back(temp); } in.close();
order(data);
ofstream out("d:\\out.txt"); if(!out) { cerr<<"文件不能打开"<<endl; abort(); } for(int i = 0; i < data.size(); i++) out<<data[i]<<" "; out.close(); return 0;}
void order(vector<int>& data) //插入排序{ int count = data.size(); int i, j;
int temp; for(i = 1; i < count; i++) { temp = data[i]; for( j = i; j > 0 && data[j-1] > temp; j--) data[j] = data[j-1]; data[j] = temp; }}
