c++ - 写入文件时遇到问题(ofstream)

Question

我想在文件上写点东西。但它只是没有像它必须假设的那样编写。

void main()
{
    int accno;
    char name[20];
    float deposit;

    clrscr();

    ofstream writefile("icici.txt");

    cout<<"enter your saving bank account number";
    cin >> accno;

    writefile << name << endl;

    cout<<"\n\nYour good name:";
    cin >> name;
    writefile << name << endl;

    cout<<"\n\nKey in recent deposit in Rs:";
    cin >> accno;

    writefile << deposit << endl;

    writefile.close();

    cout << "\n\nFile is created successfully...\n\n" << endl;
    ifstream readfile("icici.txt");
    readfile >> accno;
    readfile >> name;
    readfile >> deposit;
    cout<<"\nContent of file is icici.txt is read as follows:\n";
    cout<<"\nSaving bank account number:"<<accno<<endl;
    cout<<"\nCustomer name smt/shri:"<<name<<endl;
    cout<<"\nDeposit amount in Rs:"<<deposit<<endl;
    getch();
}

它在文件中是这样写的:

我做错了什么？

Answer 1

首先writefile<<name<<endl , name字段未定义。也许你想写accno而不是 name ？
