C++ weirdness

[YoyotheChameleon]

Hello everyone, I'm making a game of hangman. I got the original code from err0r1212, and wanted to build upon it and change some things. However, I'm not familiar with the bool function. I'd like to remove the "play again" function, but if I delete it errors come up of course. I'm really new to c++, but I know the basics. If someone could help me remove the play again function, I'd really appreciate it :)

It's not clear if you want the game to continue indefinitely, or to only play once.
The simplest solution is to change playAgain() to return a fixed value.

bool playAgain() // function to play again while clearing system
{  return false;   //  Assumes you don't want the game to play indefinitely
}

If you want the game to play indefinitely, then return true.

If you want to get rid of the function altogether, then you will have to get rid of the do/while loop that calls playAgain().

PLEASE ALWAYS USE CODE TAGS (the <> formatting button) when posting code.
It makes it easier to read your code and also easier to respond to your post.

Actually you will see where the function is used much more clearly if you write your code in a better layout (i.e. use indentation).

In fact you only use playAgain in a do...while construct, which reads

do
// play the game
while(playAgain()) // == true).

As stated before, you have to remove the whole cycle if you want to get rid of the function.
