While Loop

nani1799 (5)
Hi, I'm trying to edit below using while loop to allow user to keep selecting choices until exit (option 4) is selected. This is my first while loop program and I've been trying to figure it out for a while, so it really bugs me to not be able to figure it out. I know it is probably really simple too! Any help or insight would be greatly appreciated.

while (option < 4)
{
cout << "Please select an option: " << endl; \\ This doesn't work, but tried it
}


This will spam you with "Please select an option: \n" for all eternity.

Am I on the right track with placement of while loop and closure?

Well, 2 things:

One line comments are double slashes //, not backslashes \\.

You need to include the following switch into your while block, and you also need to include code that actually prompts the user to enter an option..
