第十四周程序阅读——例十一：体会对文本文件的访问

#include<iostream>
#include <fstream>
#include<cstdlib>
using namespace std;
int main( )
{
int a[10];
ofstream outfile("f1.dat",ios::out);//定义文件流对象，打开磁盘文件"f1.dat"
if(!outfile)                        //如果打开失败，outfile返回0值
{
cerr<<"open error!"<<endl;
exit(1);
}
cout<<"enter 10 integer numbers:"<<endl;
for(int i=0; i<10; i++) //向磁盘文件"f1.dat"输出数据
{
cin>>a[i];
outfile<<a[i]<<" ";
}
cout<<"The numbers have been writen to file. "<<endl;
outfile.close();       //关闭磁盘文件"f1.dat"
return 0;
}
