Help me expand my beginner program?

[Venomcxx]

Okay well my code below works fine right now. It is a simple journal/diary program, after I create the entry, I can then read it when choosing "View Entries" in my main menu, but I want to know how I can continue to add more entries after the first one I add, because if I try right now it just overwrites the old one (I understand why it does this, I just don't know how to achieve what I want it to).

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

class Entry{
public:
	void setEntry(string x){
	entry = x;
	}
	string getEntry(){
		return entry;
		}
private:
	string entry;
};

bool mainMenu(Entry & obj){
	string choice;

	cout << "\n" << "< Menu >";
    cout << "\n01. Create a journal entry.";
    cout << "\n02. View your journal entries.";
    cout << "\nEnter your choice or /exit to exit the program: ";

	getline (cin,choice);

	if (choice == "01"){
	string x;
	cout << "\n< Create Entry >" << endl;
	getline (cin,x);
	obj.setEntry(x);
	cout << "\nYour entry has been saved, returning to the main menu.." << endl;
		return true;
	}
	else if (choice == "02"){
	cout << "\n< View Entries >" << endl;
	cout << obj.getEntry() << endl;
		return true;
	}
	else if (choice == "/exit"){
		string warning;
	cout << "\nAre you sure? Type /exit to exit or /menu to return to the main menu: ";
	getline (cin,warning);
	if (warning == "/exit"){
	return false;
	}
	else if (warning == "/menu"){
	return true;
	}
	}
}

int main()
{
	bool loop = true;
	Entry MyEntry;

	cout << "Welcome to this program!" << endl;

	while (loop)
		loop = mainMenu(MyEntry);

	cout << "\nExiting program!" << endl;
	
}

use list of entries instead of string..
for e.g list<string> entries;

hope this helps!

Could you give me some direction on how I would implement that? Like what exactly I should replace? Im new to C++ its my first language, sorry if I sound dumb.

What i was trying to say you is

class Entry{
public:
	void setEntry(string x){
	entry = x;
	}
	string getEntry(){
		return entry;
		}
private:
	//string entry;
        list<string> entries;
};
