***Please help me to put the difficulty level. I don't know what would be the correct codes and where to put it. I'm just a beginner help me please cause it's for my project. Thanks in advance. :)

[AbstractionAnon]

What do you mean by "help me to put the difficulty level"?

Do you mean you want to implement multiple difficulty levels?
If you want to do that, I would suggest creating a table to words and difficulty levels.
Example:

 
struct 
{ int  dif_lvl;
   string word;
} words[] = { 1, "india",
                      1, "japan", 
                      2, "nepal", 
                      1, "china",
                      3, "madagascar" 
//  ... etc 
                   };

PLEASE USE CODE TAGS (the <> formatting button) when posting code.
http://v2.cplusplus.com/articles/jEywvCM9/
It makes it easier to read your code and it also makes it easier to respond to your post.

**I don't get it why I'm getting so many errors

[Ispil]

Well, let's take a look...

Alright, I see the build errors. Easy ones would be the fact that you can't count braces; if you actually intent out your code (whitespace isn't restricted whatsoever here, so go crazy with it) you will easily see where you forgot a closing brace. That, and you use cin to input a string instead of getline. That's just the build errors, though.

And use code tags!

[AbstractionAnon]

You've been asked twice to use code tags.

I'm not going to respond to your post until you do so. It's impossible to point to specific lines that have problems without line numbers (provided automatically by code tags).

Hint: You can edit your second post, highlight all of your code and press the <> formatting button to the right of the text entry box.

[Codermik]

If you actually listened and took my advice from your double post then you would have solved this issue already. Refer to this post: http://www.cplusplus.com/forum/beginner/136906/#msg727719

I would strongly suggest you read up on functions (link in that post) because you don't seem to grasp how they work. Anyway, taking what I said in my previous post your code would look like below. However, there is a lot of repeated code (i.e. each level has pretty much the same code) which could be improved a lot.

As AbstractionAnon and Ispil have stated, use code tags - it makes your code so much easier to read for those who are considering helping you.

Lastly before I link the code, you should only use srand once in your code and not multiple times, place it at the top of your main function.
