Help with unrecognized input

Reiv63 (13)
This is a function call for my Wheel of Fortune game. And I'm getting a hard time pinpointing where did i go wrong, When i Run the program after:
Line 50 --
1
2
3
 
cout << "Guess a consonant letter or Solve the word" << endl;
getline(cin,guess2);
cin.ignore(256, '\n');

its directing to the:
Line 81 --
1
2
 
else if(copy2.find(guess2) != -1){	
cout << endl << "Correct letter!" << endl;

whatever letter/word i input. sorry, if its confusing, its hard to explain without running it directly.

I would guess that that cin.ignore() call is part of the problem. Remember getline() extracts the end of line character and discards it, so that ignore will sit there and wait until the user enters another entry, which will then be discarded.

You really should stop using all of those goto statements and learn to use one of the other more acceptable loop constructs along with functions. IMO this function is trying to do too much and should be broken up into smaller functions.

thank you for the heads up, i'll try another method and remove getline. and as for goto, im still learning alternatives for something so similar like that, so i used the goto for the time being.
what i dont understand is, in my other function, that is similar to this, it works, but here it doesnt. the first level, this is the second lvl

my function for the first level, very similar to my int lvl2(); but this one works.

thank you for the heads up, i'll try another method and remove getline.

The getline() is probably not the problem, the problem is probably the ignore().

im still learning alternatives for something so similar like that,

I suggest you stop what you're doing and do this learning now. You should forget that you have ever heard about the goto statement.
