输入的数字与结果不一样

Question

我的代码有问题，debit.txt的结果与输入的不一样：

long int s;

ofstream outfile;
outfile.open("saldo.txt");
cout << "Masukan jumlah saldo kredit : "; cin >> s;
outfile << s << endl;
outfile.close();

我的saldo.txt

long int db;

ofstream outfile;
outfile.open("debit.txt");
cout << "Masukan jumlah saldo kredit : "; cin >> db;
outfile << db << endl;
outfile.close();

我的debit.txt

long int s, db;

    ifstream infile;
    infile.open("saldo.txt");
    infile >> s;
    cout << s << endl;

    infile.open("debit.txt");
    infile >> db;
    cout << db << endl;
    infile.close(); 

}

这就是结果 cek.txt

当我尝试在 debit.txt 中输入 150 时，结果是一个随机数，但 saldo.txt 却不是，有人可以帮我解决这个问题吗？ :)

您在打开 "debit.txt" 之前没有关闭 "infile" 对象。请按照下面的说明关闭 infile

long int s, db;

ifstream infile;
infile.open("saldo.txt");
infile >> s;
cout << s << endl;


infile.close(); //close here.


infile.open("debit.txt");
infile >> db;
cout << db << endl;
infile.close();

输入的数字与结果不一样

The number entered isn't the same as the result
