I Need C++ Help

[967L1hU5]

So, in a game I'm making, the players have the option to invest their money, using said code:

            if (money >= 200)
            {
                cout << "How much would you like to invest? You have $" << money << "." << endl;
                cin>> invest;
                if (invest > money)
                {
                    cout << "You don't have that much." << endl;
                }
                if (invest <= money)
                {
                    cout << "You're about to invest $" << invest << ". Are you sure?" << endl;
                    string investyn;
                    getline (cin, investyn);
                    if (investyn == "yes")
                    {
                        money = money - invest;
                        cout << "You have invested $" << invest << "." << endl;
                        investyn = 1;
                    }
                    if (investyn == "no")
                    {
                        cout << "Okay than." << endl;
                    }
                }
            }

(Sorry for the long spaces, it's quite a few "if's" in)

The only problem is that at cout << "You're about to invest $" << invest << ". Are you sure?" << endl; , it seems to end the "if" function their, and returning to my "while" loop. It is totally skipping the getline, so there's no chance that I just misspelled my command. Does anyone know what I did wrong? Becuase this is a big project for me (over 2,200 lines of code) and I'd hate to kill it or leave out a good feature because of this.

It's something to do with the state of cin. There are a lot of posts on this site that deals with left-over characters in the input stream. I think one of the options is to call ignore (cin.ignore() ). Try searching this site for those issues.

[967L1hU5]

What would (cin.ignore() do?

[967L1hU5]

So it cuts, for no better words, strings?

[kooth]

Extracts characters from the input sequence and discards them.

The extraction ends when n characters have been extracted and discarded or when the character delim is found, whichever comes first. In the latter case, the delim character itself is also extracted.

Parameters
n 
    Maximum number of characters to extract (and ignore).
    This is an integer value of type streamsize. 
delim 
    Delimiting character.

I owe to you the future of my game. Which if you'd want to check it out... http://dl.dropbox.com/u/17356291/web/downloads/Actual%20Entity.exe That version is slightly outdated thou.

I'm glad I was able to help. Good luck, and keep us all posted on your progress!

[967L1hU5]

Indeed I will. BTW, do you know how to make a linux/ubuntu executable file from Windows? I'm using Windows 7 and code::blocks

[kooth]

I don't know what code::blocks are, but the code you have posted should port just fine. You should have the GNU C++ compiler and GNU make (gmake) on the system, if not, they are free downloads (just Google them!)

[967L1hU5]

Code::blocks is a free and open source IDE for C/C++. I think there's also plugins for python.
