輸入查詢到文本文件

Question

這裏是我的代碼：

#include <iostream> 
#include <fstream> 
using namespace std; 

int main() 
{ 
    int would; 
    string pass; 
    cout << "Password Manager v.1" << endl << endl; 
    cout << "What's the secret?" << endl; 
    cin >> pass; 
    if(pass == "youcantknowsorry"){ 
     cout << "Access granted." << endl << endl; 
     cout << "Would you like to add a new password (1) or view your passwords? (2)" << endl; 
     cin >> would; 
     if(would == 1){ 
      ofstream myfile; 
      myfile.open ("example.txt"); 
      myfile << "NewPassword" << endl; <--- HOW CAN I MAKE THAT INPUT? 
      myfile.close(); 
     } 
     if(would == 2){ 
      cout << "Your passwords will open in a text file."; 
     } 
    } 
    return 0; 
} 

我想寫一個密碼管理自己。我使用類似cout的方法成功創建，打開並寫入文件。但是，我需要用戶輸入信息並將其保存在文件中。

Answer 1

我們假設這只是讀取輸入和寫入文件，而不是管理純文本文件中的密碼。 你有

int would; 
cin >> would; 

和

string pass; 
cin >> pass; 

所以，你已經知道如何從用戶讀取輸入。 同樣，您可以讀取用戶的密碼，它傳輸到文件：

string password; 
cin >> password; 
myfile << password << endl; 

Answer 2

你需要這段代碼的if語句中：

cin >> would; 
if (would == 1) 
{ 
    std::cin >> pass; 
    std::ofstream("example.txt") << pass << std::endl; 
}
