Help on the final parts of my calculator

sunni (11)
Hello all!

You probably remember me from the last week or so. I have another question for those of whom might be interested.

I've finished my calculator for the most part, and now I'm having trouble with two things. The first is that every time I select the number seven to exit the program, and I put in the character y or n, the program seems to go absolutely haywire.

Can anyone help me with this? There's a nested if statement that turns the program off if the answer is y.

Shot in the dark, you declare option as an int but then on line 170 stuff a char in it via cin>> try using an actual char instead of option.

EDIT: also, putting any code after return 0; is redundant.
The proper use of system () is system("use the quotes"); and using system for anything but little programs or homework (which I'm guessing this is) is a really bad idea.

EDIT EDIT: don't use nested ifs like that. Do this instead:
1
2
3
4
5
6
7
8
 
if(option == n)
{
      break;
}
if(option == y)
{
      cout << "We will meet again, I am sure.";
}

Dear Sargon,

Thanks for that info. I worked on the if statements, but I decided to change them to else since it would be a bit easier.

I've now gotten this:

And It says for the error, this:

expected "}" at end of input. What might I be doing wrong at line 181?

Hi I'm a complete noob to c++. but I believe the error you get in the end is because the "}" you placed on line 181 is connected to the one placed on line 21, instead of line 8.

Try changing that :) If that doesn't help, I'm sorry.

the error that comes up is that the file cannot be opened, and permission has been denied.

Ok ok, my apologies, I made a mistake in my first post. Here's what's wrong in order.

1st: option is declared as an int on line 9. This is a good thing since you use it to input numbers for most of the program. However, "y" and "n" are of the char (character) type and therefore cannot be stored in the variable option. Therefore, you must create a new variable (called whatever you want) and make it a type char like this: char nameofvariablehere;

2nd: on line 170 you then put cin>>nameofvariablehere instead of option. Because it is a char you must also modify you if statement like so: if (nameofvariablehere=='y')

3rd: to loop back the menu replace line 177 with break; Also, to close the program is they input "y", add return 0; after line 173 (but before the "}" symbol)

Finally: Your error, when is it happening? When you compile? What file can't be opened?

Should it look like that?

Also, the only error left is the error of the file not being able to be opened , and that is after I build the program.
sargon94 (405)
line 171: if (confirm == 'y') remember the quotes.

Aside from that everything looks fine :D

So... you build it, and then when it tries to run it says it's unable to open the .exe? Erm... check with your OS (I'm guessing you're using windows?). Check your account privileges. If you're in a class ask your teacher.

Ah, well this is my final. LOL.

I thank you all for helping me. I'm going to turn this into my teacher with the IPO CHart and Flowchart and I am going to get to bed.

Over winter break, I am going to study this at my leisure.
