[QUOTE=Werem00se;32273415]So, whenever I tried to convert Fahrenheit to Celsius in a one step line it gave me the wrong answer. No matter what I tried. So, I had to use this confusing line of code.

double FahrenheitToCelsius(double fehrenheit)  
{
   double placeHolder = fehrenheit - 32;
   fehrenheit = placeHolder * (5.0f/9.0f);
   return fehrenheit;

you could have just done

Don't you mean:

fahrenheit -= 32;

Or alternatively,

for(int i = 0; i < 32; i++)
{
  fahrenheit--;
}

If you're having trouble with the 1.6 version (which I don't remember being supporting vs2010), then you should REALLY switch to 2.x-git. It's very much better, than trying your head at something like that old 1.6 version.

I believe with Java you must use the equals methods when comparing strings.

As for your out of bounds issue. Do some bounds checking. If you split an empty line you will end up with an array that has only 1 element.

I'm only using it for OpenGL as well. That's why you decide which "parts" of SFML you use and which parts you compile. You don't need to compile, for example, sfml-audio to get visual feedback.

No, but all the implementation files, or you can compile them into an immediate representation (object files) which can be linked together in another step.
And that's why you use build-systems, fancy editors or IDEs (or a combination).

I'm currently enrolled in a programming class in school and we've just begun to learn visual basic. I decided to dick around in C# a little bit and I've taken on the challenge of creating an incredibly simple game.

[img]http://filesmelt.com/dl/game4.png[/img]

When the 'Attack' button is clicked, a random number will be generated and subtracted from the enemy's health. The same will be done for the player's health. When the player's or enemy's health reaches zero, a message box will display a win/lose message. I am having trouble where the health variables will reset to 100 every time the button is clicked, even though I put the health variables outside of the button's click event.

        int playerHealthInt = 100;
        int enemyHealthInt = 100;

        private void attackButton_Click(object sender, EventArgs e)
        {
            System.Random randnum = new System.Random();

            int playerHealth = playerHealthInt - randnum.Next(100);
            int enemyHealth = enemyHealthInt - randnum.Next(100);

            playerHealthLbl.Text = playerHealth.ToString();
            enemyHealthLbl.Text = enemyHealth.ToString();
        }

Sorry if I sound dumb. I'm new to programming.

[/QUOTE]
You're creating temporary variables here and assigning the new health into them. You want to replace the old variables that you made class-wide:
[csharp] playerHealthInt = playerHealthInt - randnum.Next(100);
enemyHealthInt = enemyHealthInt - randnum.Next(100);[/csharp]
Alternatively:
[csharp] playerHealthInt -= randnum.Next(100);
enemyHealthInt -= randnum.Next(100);[/csharp]

[jalb]

Are you sure scoreupdate_Tick is being called frequently? It may be working just not drawing the next score to the screen. In fact, why not just update the scorelabel in all of the HitAreaX_Click's? Maybe make your scoreupdate_Tick an "UpdateScore" method instead and call it any time you change the score.

Also, it might be worthwhile to look into arrays.

Because he's hardcore like that.

I've been doing some C++ tutorials lately and I have this urge to try something of my own after a few of them. I already have a simple program that has you put in 2 numbers, adds them and prints the answer but I wanna extend this to having the user pick between the big 4 of maths before giving the answer.
Thing is, I don't have the slightest idea on how to progress from what I have now. Anybody who can give me some pointers on how to proceed or improve my coding in general? Besides telling me that, as it stands, my methods are poorly designed?
[csharp]

}

int DoMultiply (int x, int y);

Oh god, I just noticed quite a few other faults.
First, move the using namespace std; to the top of the file.
Also, when you're calling your functions, you're passing (x + y) to them. You should pass x and y by using DoDiv(x, y); and so on.

[gummiwipfel]

by the way:

void operation;
cin >> operation;

you are trying to read something into a variable of type 'void', what won't work
in this situation you should probably use std::string
and in your IFs you are currently comparing 'operation' to (undefined) variables, you should instead write if (operation == "add") and so on

Working on a simple text based RPG.

        int playerHealth = 100;

cout << "Lets start with your name, what is it?: ";
		cin >> playerName;

	if (playerName == "Toby" || "toby")

		else
		{
				cout << "Wrong. You are beaten with a whip. You take ten damage.";
				 playerHealth = playerHealth - 10;
				 cout <<  "Your name is Toby. Got that?";
		}

There's just a bit of it. Basically when you enter your name, unless it's Toby it should make you take ten damage. But no matter what I enter as a name, it outputs 'good choice'. I thought the else clause is supposed to execute if no other statements are true. Can someone help? Here is the entire code. [url]http://www.text-upload.com/read.php?id=138705&c=7070157[/url]
