给你个例子，只要在构造函数中写入即可：
void getshuju::duqu()
{ cout<<"输入i的数值即总共的期数"; cin>>i;
//char filename[20]="F:\\158\\158.txt";
//   ifstream inf(filename,ios_base::in);
if(inf)     //文件打开成功
{for(int j=0;j<i*8;j++)
//读入八个整数inf>>a[j/8][j%8];}
else
{ cout << "open file fail" << endl; exit(1);}  }

谢谢

。我刚刚调的是这样的。成功了。
class txtRead{
private:
    fstream newsFile;
    int rows;
    int cols;
    char news;
public:
    void printTxt();
    void countNum();
    txtRead();
};

txtRead::txtRead(){
    newsFile.open("I:\\NewBrowserText.txt");
    if(!newsFile){
        cout<<"you get wrong file's address!"<<endl;
    }
}
