我想用C++编写一个输出电子邮件系列地址的程序到clinet.dat文件夹里，自认为代码没问题，可是运行就显示
“File could not be opened”现讲代码贴示如下，希望各位帮我看看八，菜鸟小弟在此谢过！！！
#include <iostream>
using std::cout;
using std::cin;
using std::ios;
using std::cerr;
using std::endl;
#include <fstream>
using std ::ofstream;
#include <cstdlib>
int main()
{
ofstream outClientFile ( "clients.dat, ios::out");
if (!outClientFile)
{
cerr<<"File could not be opened."<<endl;
exit ( 1 );
}
while ( 1 )
{
for (int i=1;i<=300;i++)
{
outClientFile <<"0372"<<i<<"@fudan.edu.cn;\n"<<endl;
cout<<"?";
}
}
return 0;
}
