Need Help with Menu

[camwhyy]

Hello everyone I really need help with this menu :( I have been really struggling with it for the past few days now and cant figure out what I did wrong and what I need to do to press on.

What I need to do is a program that displays 4 options, then when the number is entered that corresponds with the option it does what it is supposed to do. My full code is pasted here:

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

int main()
{
	int select

		cout << "Select an Option: " << endl;
	cout << "1. Add Name to File." << endl;
	cout << "2. Display Names on File." << endl;
	cout << "3. Clear the File." << endl;
	cout << "4. Exit the Program." << endl;
	cout << "Selection: ";
	cin >> select;

	if (select == 1); // Write names to file Names.txt
	{
		ofstream outputFile;
		string name;

		outputFile.open("names.txt");

		cout << endl;
		cout << endl;
		cout << "Adding a Name to File." << endl;
		cout << "Enter a Name: ";
		cin >> name;

		outputFile << name << endl;
		cout << "Name added successfully!" << endl;

		outputFile.close();
		cout << "Done." << endl;
	}
	if (select == 2); // Read names from the file Names.txt
	{
		ifstream outputFile;
		string name;

		inputFile.open("names.txt");
		cout << "Names from the file names.txt: ";

		inputfile >> name;
		cout << name << endl;

		inputFile.close();
	}
	if (select == 3); 	//Clear the file Names.txt
	{
	
	}
	if (select == 4);  //Close the program
	{
		cout << "Exiting Now..." << endl;
	}
}

Now onto what I need help with if you haven't figured it out

Option 1 works ok and I am able to write a name to the file, but I cannot add more than one name to the file. When I enter a new name it overwrites the name that is already there. I need to want to put multiple names on the file:

if (select == 1); // Write names to file Names.txt
	{
		ofstream outputFile;
		string name;

		outputFile.open("names.txt");

		cout << endl;
		cout << endl;
		cout << "Adding a Name to File." << endl;
		cout << "Enter a Name: ";
		cin >> name;

		outputFile << name << endl;
		cout << "Name added successfully!" << endl;

		outputFile.close();
		cout << "Done." << endl;
	}

Also with this section I would like to have the option to go back the the 4 options (maybe press B to go back to main menu?) and if I choose option 1 again I can add more names to the file Names.txt

My next question is with option 2. When at the main menu I cannot select #2 it just goes instantly into option 1 and IDK why! Without that working properly I cannot move onto the next 2 options.

For option 3 I want it to erase all the names on the file and say "Names have been removed" I cannot figure that out at the moment either since I literally do not know what the code is to clear a file.

And for option for I just want it to give you the option to press 4 to exit and it displays the message "Exiting now..."

Again any help is appreciated I have tried to do as much as I could on my own but alas I have been un-successful

Use outputFile.open("names.txt", ios::app);

go back the the 4  use a loop , with a switch

cannot select #2

I cant figure out use else if , or just stick to a switch

erase all the names on the file and say "Names have been removed" just open and close the file for output and write some white spaces , not a very good idea

press 4 to exit a a switch will be your friend

[camwhyy]

Use outputFile.open("names.txt", ios::app);

Where am I putting that? In the field for Option 2?

Line 24 /// you said you aren't able to write multiple names to your file that will solve your problem

Ok I have fixed the selection issue but I am still not able to clear the file (names.txt)
