what are the errors?

[prvn20]

There are 80 errors in total if you try to run it using dev c++ :(((

[Ganado]

Well, might as well start listing them then, I doubt someone is going to find all 80 and list them him or herself.

but here's one or two:
cin >> level >> endl;
You can't use endl like that, it needs to just be
cin >> level;

Also,

	string word; //Delcared here!
        ....
	if(level == "Easy")
	{
 		string word; //Declared here again, Line 26! Error! 

[prvn20]

Thanks dude that helped a lot hehe.
2 errors left: 254 1 [Error] expected '}' at end of input
82 2 [Error] a function-definition is not allowed here before '{' token

[Little Bobby Tables]

ganado: you are wrong. read up on scope. http://coliru.stacked-crooked.com/a/577e4f3e978c3475

[Codermik]

Your missing the whole point of functions and their prototypes. You declare your prototype on line 8 and then incorrectly write the actual function multiple times inside your main.

You need to have your function outside your main and call it when needed.

For example:

#include <iostream>
using namespace std;

// prototype
int letterFill(char, string, string&);

int main()
{
	int matches;  // to hold result of function call.

	matches = letterFill( /* pass parameters from game here */ );

	// matches now holds result of letterFill call

	return 0;
}


// Your function outside of main.
int letterFill(char guess, string secretword, string &guessword)
{
	int i;
	int matches = 0;
	int len = secretword.length();
	for (i = 0; i< len; i++)
	{
		// Did we already match this letter in a previous guess?
		if (guess == guessword[i])
			return 0;
		// Is the guess in the secret word?
		if (guess == secretword[i])
		{
			guessword[i] = guess;
			matches++;
		}
	}
	return matches;
}

You should have a read about functions: http://www.cplusplus.com/doc/tutorial/functions/

What also may be helpful to you is a hangman I wrote for another user, this will give you some idea on what I mean regarding calling functions and obtaining their return values.

Hope this helps, take care.

Softrix,
I wrote how you said...
But it's giving an error which says
197 13 [Error] expected primary-expression before ';' token

[Sausage]

This is your issue. First off, you're passing values that don't exist.

int matches;  // to hold result of function call.

		matches = ;int letterFill (char guess, string secretword, string &guessword);

Also you don't really need that many comments, it's lowering your codes readability.

[Ganado]

Little Bobby Tables, glad you saw my mistake, woops, never had a reason to do anything like that so I just assumed.

[Little Bobby Tables]

no problem ganado ;)
