Thread: Questions about this program in c++

Well, that's funny. You didn't add the closing brace after the loop like I said (I even gave you the line number).
Nor did you take the advice in post #8 about "main()" returning an int, not void.

Did not work, my friend began to despair

Indeed.

Code:

Me:  "The answer to question #4 is 'B'."

You: "How do I work this pencil?"

Excuse me I'm sorry because I am new to the language c

That's fine, but we have not even gotten to any programming related advice. We're trying to start by making sure the code you posted has the correct syntax so you can compile it. I told you exactly what to type, in the exact location, and you didn't even get that far.

When you hit a roadblock like this, the best thing to do is take a step back. Go back to what you know, review what you've learned, and try going forward again slowly, making sure you understand each small step.

It's a bit suspicious that you claim you created* this code, but can't figure out that a brace is missing (especially when it was pointed out explicitly in this thread).


(*) I'll give you credit that you said "create" this code, and not "write" this code, because it is obviously a copy/paste mish-mosh of code written by others (i.e. here).

This is the last update and there is one error

Now you're starting to look like a troll.

Count the opening braces in your code ( { ).
Count the closing braces in your code ( } ).

Tell us how many of each you have.

Done that gave me 12 error
I will try later
Thank you
