Looping menu with external file input not working

[NorthFLS]

Hello everyone, so I'm attempting to make a file to keep important activities and dates, however, I cannot get my menu to loop back after the file is displayed. This is my first post and I'm trying to follow the guidelines as best as I can, if I have done anything wrong please correct me. I can not tell if it is a problem with my main function or my readFile.

void readFile()//this is my read file/ display info.
{

    ifstream HomeWorknInfo;
    HomeWorknInfo.open("dates.txt",ios::in);
    if(!HomeWorknInfo.is_open())
    {
        exit(EXIT_FAILURE);
    }
    if(HomeWorknInfo.is_open())
    {
        string line;
        while(getline(HomeWorknInfo,line))
            cout << line <<"\n";
        
    }
    HomeWorknInfo.close();

}


int main()//my main with the switch function
{
    unsigned short menuChoice=0;

    do
    {
        getMenu();
        cin >> menuChoice;
        switch(menuChoice)
        {
            case DisplayFile:
                readFile();
                break;

            case AddToFile:
                addToFile();
                break;

            case Exit:
                return 0;
            default:
                cout << "You have entered an invalid menu choice.\n"
                     <<"Please try again";
                getMenu();

        }
        //menuChoice=0;
    }while (menuChoice != Exit);
    return 0;
}

A couple of minor points.
L10: There is no reason to call is_open() a second time. You could use an else, but really there is no need for the second if statement at all.
L28,45: If menuChoice is invalid, you're going to call getMenu() twice. Remove line 45.

Other than those two minor points, I don't see anything wrong with your code.
Have you stepped through your code with a debugger?

You don't need L17 as the file destructor closes the file. readFile() can just be:

void readFile()
{
	ifstream HomeWorknInfo("dates.txt");

	if (!HomeWorknInfo)
		exit(EXIT_FAILURE);

	for (string line; getline(HomeWorknInfo, line); )
		cout << line << '\n';
}

I would replace L41 with just break; so that the while loop is exited normally and any post exitr code can be after the while.

I cannot get my menu to loop back after the file is displayed.

What does it do instead?

There seems nothing wrong with readFile(). So it is most likely somewhere else.

@AbstractionAnon I'm pretty new to coding and I've been trying to figure out how to use the debugger, ill definitely give this a try! Thank you.
