#include <fstream>#include <iostream>using namespace std;int main(){ int a[10]; ofstream outfile("1.txt",ios::out); if(! outfile) { cout << "open error!" << endl; exit(1); } for(int i = 0;i < 10;i++) { cin >> a[i]; outfile << a[i] << " "; } outfile.close(); return 0;}以上这段代码可以运行，并在默认路径下可以将数组中的内容输入文件中。#include <fstream>#include <iostream>using namespace std;int main(){ int a[10]; ofstream outfile("d:\1.txt",ios::out); if(! outfile) { cout << "open error!" << endl; exit(1); } for(int i = 0;i < 10;i++) { cin >> a[i]; outfile << a[i] << " "; } outfile.close(); return 0;}这段代码就改了一下打开文件路径就打不开，为什么？请高手指点！
