如何將完整的句子輸入到.txt文件中C++

Question

我需要改進將數據寫入文本文件的幫助。我已經成功地寫入文件，但該程序只允許我存儲一個沒有空格的字符串。所以我需要幫助的是使用一個變量將完整的句子寫入文件。 '

這裏是代碼，程序應該是一個基本的議程/計劃。

〜編輯〜 我忘了提及我正在嘗試cin數據。 例如：它詢問您的學校作業是什麼，然後鍵入「做作業」並按下回車鍵。

#include <iostream> 
    #include <fstream> 
    #include <stdlib.h> 
    #include "agenda.h" 

    using namespace std; 

    int main(){ 

    string write; 
    string title; 
    string answer; 
    string school = "sch"; 
    string birth = "bir"; 
    string quit = "quit"; 
    string view = "v"; 
    string append = "a"; 
    string clear = "c"; 
    string back = "b"; 
    string yes = y; 

    cout << "------Welcome User!------\n"; 



       cout << "\nSCHOOL PLANNER\n\n"; 

       cout << "Pick your option: \n\n" << 
         "view(v)\n" << 
         "append(a)\n" << 
         "clear(c)\n" << 
         "back(b)\n"; 
       cin >> answer; 

       if(answer == view){ 

        system("cat ~/Desktop/agenda2/school.txt"); 

       } 
       else if(answer == append){ 

        title = "Date: "; 
        cout << "Date: "; 
        cin >> write; 
        Write_School(title, write); 

        title = "Class: "; 
        cout << "Class: "; 
        cin >> write; 
        Write_School(title, write); 


//where The problem is 
        title = "Assignment: "; 
        cout << "Assignment: "; 
        cin >> write; 
        Write_School(title, write); 

        cout << "[DATA SAVED]"; 
       } 
       else if(answer == clear){ 
        cout << "Are you sure you want to delete the files forever?(y/n)"; 
        cin >> answer; 
        if(answer == yes){ 

         Clear_Text(); 
         system("clear"); 
         cout << "Text file emptied.\n\n"; 
        }

         cout << "All data saved.\n\n"; 
        } 
       } 
       else{ 
        cout << "[ERROR INVALID ENTRY]\n\n\n"; 
       }  
return 0; 


      } 

//here is the header file

旁註 -compiled在Ubuntu終端 -cin.get和cin.getline沒有工作（除非我用他們錯了） -been尋找一個在某個地方回答很長一段時間，這是我沮喪遇害之前的最後一招！

嗨，我是傻的頭完全匿名的..我想你需要聲明在您輸入要去..

例子.. 這是如何創建自己的文件名..和追加TXT在你的文件裏面。我一直在玩我的註冊系統，我想它如何寫自己的文件，並把所有的TXT文件內..

    string name,fileName; 
       fstream file; 
       cout << "Enter your name: " <<endl;   
       cin>> name; 
       fileName += ".txt"; // important to create .txt file. 
       ofstream createFile; 
       createFile.open(fileName.c_str(), ios::app); 
       createFile << name << endl;   
       if (file.fail()) { // check if file is opened successfully 
       cout << "Error Opening file ... " << endl; 
       }else{ 
       file<<name<<endl;
