Did you set it up properly? If you're using Visual Studios 2010, you only need to hit Properties -> VC++ Directories and set both the Include and Lib directories (x86 subfolder in Lib)

Then under Linker -> Input -> Additional Dependencies you add:
SDL.lib
SDLmain.lib

EDIT (the entire process with visual aids): http://lazyfoo.net/SDL_tutorials/lesson01/windows/msvsnet2010e/index.php

Sure 'bout that? I have a 32bit system so I chose x64 NEEEVERMIND I know that I'm an idiot.



Oh hey so it worked.

Weird. Getting a different error now, but at least that one's gone.

[Stargrasper]

Don't worry.  We're all idiots.  Some more often than others...

Anyway, a Linker is the thing that takes code from a library and plugs it into your code.  It kind of helps for using external libraries.

So what error are you getting now?

It's actually a mistake I do all the time :V

Anyway, a Linker is the thing that takes code from a library and plugs it into your code.  It kind of helps for using external libraries.

I already checked wikipedia et al. for an explanation. Comprehension: N/A

So what error are you getting now?

LNK1104. Basically, it cannot find SDL.lib.
The problem with googling for a solution you only get posts on random forums from people who assume that whoever reads their posts knows exactly what to do.

I'm currently checking my settings and stuff.

[Darvi]

Aaaand fixed.

If some other sod googles for a solution, Linker>General>Additional Lybrary Directories = whereverSDLis\SDL\lib\x86

Hey Errol, before I forget, you should change one of your lines to this

Code: [Select]

bi = ImageIO.read(new File(@"./img/tileclose.png"));

Perhaps I'm just too tired to spot my mistake, but is there any reason why this program won't do simple multiplication?

Spoiler (click to show/hide)

Code: [Select]

#include <stdio.h>

int main (void)
{
//Declarations
double num1;
double cents;


//Get number
printf("Enter the amount of money you have: ");
scanf("%f", &num1);


//Calculations!
cents = num1 * 100;


//Result
printf("\n You have %.2f cents. Thank you!\n");
return 0;
}

Eventually, this thing is supposed to figure out exactly how many dollars, quarters, dimes, etc you have, but first I need cents. It won't give me cents, just a 0.00.

You need to put the things you are printing after the format string: printf("\n You have %.2f cents. Thank you!\n"); is very unsafe as not having the right number of arguments in a printf statement is undefined behaviour.

[Sirus]

How the hell did I miss that...
double facepalm;

[Sirus]

Ok, new problem. I made sure that cents was in the printf statement, like this:

Code: [Select]

printf("\n You have %.2f cents. Thank you!\n", cents);But then, I got this:

Code: [Select]

Enter the amount of money you have: 6.54

ents. Thank you!
Press any key to continue . . .

WHAT.

[fergus]

Check what num1 contains after the scanf().

[Sirus]

I'm not sure if there's a specific way to do that, so I just added another printf statement to display num1.
It gave me the same long-ass number, maybe minus a couple of zeros.

Not sure how 5 translated into a number which possibly outnumbers the stars in the universe, but it did. And I was doing so well on Thursday...

[RulerOfNothing]

Well, it turns out that you need to tell scanf that you want to read into a double variable, so you could either change them to floats or change the scanf statement to scanf("%lf",&num1);. (that's a lowercase L before the f btw)

[Realmfighter]

Don't think anyone's posted it yet, the people who did the AI course on the internet are doing an introduction to programming class.

Looks interesting.

[Sirus]

%lf worked. I dunno why, since my book says to use %f for doubles and %lf for long doubles, but it works.

What's worse, the textbook doesn't seem to mention what the difference between the two is.
