Saving to a file

HI all
I am trying to make a small database to help me improve my skill but i am totally stuck so can someone please help me. I want it so if the person enters n it goes to the start of the program and if the user enters y it carries on and saves the file, but I dont know how to evaluate user input.

Code:

#include<fstream>// headerfile for output/input 
#include<iostream>
#include<string> 
using namespace std; 



int main() 
{ 
    string personname;
    string activity;
    string arriving;
    string answer;
    ofstream djout; // declare our djoutput 
    djout.open("C:\\TEST.txt"); // opens/creates and edits "TEST.txt" 
    
    cout << "Please enter the persons name: ";
    getline (cin, personname);
    cout << "Please enter the activity: ";
    getline (cin, activity);
    cout << "How are they arriving: ";
    getline (cin, arriving);
    cout << "Please confirm the details: ";
    cout << "Name: " << personname << endl;
    cout << "Activity: " << activity << endl;
    cout << "Arriving by: " << arriving << endl;
    cout << "Are the details correct? Y/N" << endl;
    getline (cin, answer);
    
    
    if (answer == 'y')
    { 
       djout << personname << endl;
       djout << activity << endl;
       djout << arriving << endl;
       djout.flush(); // to save the file, you must close the file, or flush 
       djout.close(); // the buffer to the file Closing the file will not let 
                   // you access it anymore, so only call it when you are 
                   // done using the file and it will automatically save 
                   // the file for you. Flushing the buffer will write the 
                   // buffer to the file and still keep the file open, so 
                   // use this function when necessary. 
              
    }
    if (answer == 'n')
    {
               //I want it to go back to the beginning of the program
    }   
    else
    {
        cout << "System error sorry guys im not always right :)" << endl;
    }
 
    system("pause"); 
    return 0; 
}

Can someone please show me what to do lol

Many thanks

You need a loop:

Code:

do
{
    // Ask user for input here
    // Ask if input is correct or not here
} while( answer == "n" );
// Continue with rest of program here

Use a loop, then do continue to start the loop over, if you want or just let the loop do it automatically for you.
Btw, since answer is std::string, you should do

Code:

if (answer == "y")

Not the quotes there. Single quotes are for comparing a char, not a char* or any sort of string class. Though you could do

Code:

answer[0] == 'y'

this may give unintended effect since the user can enter ysklsd,vjkhdf,gjhdfgjhdfg and it'll still work (interpret as yes).
