Hi,I am trying to write a program that lets the user keep a journal or a diary.
This is what I have so far.

	return entry1;
}
void viewEntry(string entry1, int userID)

	cin >> pw;
	if(pw == userID)
	{
	ifstream inFile;
	inFile.open("journal");
	if(!inFile)

		return;
	}

	cout << entry1;
	}
}


I've set up a menu for the user to choose whether the user wants to write a new journal entry or view previous journal entries. I then used a switch control so that whatever the user chooses, it would call the necessary function. However, when ever the user choose something from the menu, the screen just goes blank and it doesn't go to my other functions. I am probably missing a lot of necessary things, but any advice would be much appreciated! please and thankyou!

p.s.
I would also like the program to be able to store more user profiles and more journal entries. I have no idea where to start with this.

Line 55 and 69 are causing logic errors. A single = is used for assignment. You want to use the comparison operator which is ==.

thanks @icethatjaw for spotting that. How ever i still can't get the switch control to work. I think something is wrong with the loop.

ch is not a character, it's an integer.
Anytime you're comparing ch, drop the single quotes (' )

nvm icethatjaw, i got the loop to go to the next step. The problem was the single quotations around the number. thanks!

Try to add .txt to the filename. Are you trying to write to an existing file?
