Section 2 Lecture 21 - Here's what I used

[layer8man]

My method was slightly different from the instructors, but it worked perfectly for me and is a little shorter:

int main()
{
do
{
PrintIntro();
PlayGame();
} while (AskToPlayAgain());

return 0;

}

I think coding this way would be more simple and convenient as well.
Is there any reason why we have to create another bool variable(bPlayAgain) to deal with play again or not?

I just found that Bryant gave a clear point of my question at another similar post

Section 2 Lecture 21 - Did it differently, and it worked. Is my solution fine?

This should work, because for all intents and purposes, in an if statement like this, 1 is identical to true. while (AskToPlayAgain()) while (AskToPlayAgain() == true) while (AskToPlayAgain() == 1) These are all essentially identical statements. Before saying anything else, let me condition my response with this: if you're the only one looking at your code, then use whatever method you are most comfortably with. Now, with that said, I myself prefer the first method, because it leaves …

int main()
{
do
{
system(“cls”);
PrintIntro();
PlayGame();
}
while (AskToPlayAgain());

return 0; //Exit the Application
}

I ended up doing the same thing, While it is faster, I assume that once things get more complicated (say, a video game) with lots of variables and bools, it might be a little more clear to use bThis or bThat or bTheOther to check things… It’s good to know both ways probably. I learned a little bit of C++ years ago, so while most of the course so far has been a refresher, I enjoy that he shows so many ways to do things and usually why you shouldn’t do things.

Also, I don’t know if he adds it later, but using the “cls” to clear the console every new game can be really useful to keep things clean, I had to Google it, but I remember using it long ago. Try for yourself if you haven’t!

I used the same approach, it looks cleaner and for this little program so far, it works:

//entry point for the game
void main()
{
    do {                
        PrintIntro();
        PlayGame();            
    } while (AskToPlayAgain());
    return;
}

I guess it will be necessary to create a separate boolean when it will be used by several different functions, like booleans in character controllers which indicate if player is jumping, falling, running, etc.
