I get the idea but I'm not sure how to code it

AchillesO23 (31)
Hi I'm creating a program to rent some movies and to return movies with a balance starting at $100. I'm making a main menu for the user to input what choices they would like to make.
I'm stuck on how to move forward like what else should I do in the case statements? Thanks

You did not have any cin statement to input "yes" or "no" for this prompt.

Edit : Can you show us the contents of "Movie.h"?

How about Movie.cpp too? We need to see it.

Your naming convention is really verbose and unnecessary.

}

You would print the name of the movies first, each with a selection number(i). Then you would ask the user to input whichever movie, indicated by the selection number(i).
Next, you should check the validity of movie_choice, then add a confirmation prompt.

    if( verify == "yes" ) break;

Finally, set the selected movie to rented.
 
 
arraymovie[movie_choice].set_is_rented( true );


if I change the objects names I get errors

Woops! My bad. I updated the names above.

cout << "Select 1 to rent a movie \n";

cout << "Select 4 to exit \n";

If you choose 1, you can rent some movies and lose your balance.
If you choose 2, you can return the movies you rent and get your entire money back.
If you choose 3, you can view your balance.
If you choose 4, you will exit the program.

Is it how things are supposed to work?

Yeah that's the idea except when a movie is returned the user doesn't get their money back.
Also if they haven't rented any movies and they enter 2, then I want it to display that they don't have any movies to return. It sounds like an if statement, but I don't know how I would code it.

Simply loop through arraymovie and check is_rented.

bool can_return{ false };

I'm having problems in my case statement. It's saying I have illegal use of '*'left operand has type float. Another is > or < has no conversion from float (__thiscallmovie:*)(void)const' to float and I'm getting pointer problems to use & in movie::get_daily_rent_cost:non-standard syntax I've never dealt with pointers so I'm not sure what to do.

This is a function. You're missing the function call parentheses.

Nevermind I got it back. Anyways how can I get my balance to be updated once a movie is rented because it subtracts the balance, but once I rent another movie it starts over at $100 (starting amount) also how can I prevent the same movie being rented assuming all movies only have 1 available?

Can anybody help me please
