/sci/ - Science & Math

Hi /sci/, i'm currently in religious high school (in France) without maths, chemistry and physics, next year i would like to go on computer science faculty, so what do i need to know and to learn for next year about maths ans physics ? Thanks.

So I picked up a C++ book from the library and downloaded Dev C++ as my compiler (bloodshed.net).

I'm into the third chapter, and I found a way around my problem, but it's just becoming too bothersome.

Once I've written the code for the example problems and they've compiled just fine, I go to run them, but the application window only stays open for a split second. I know the code has worked fine because if I hold the key down a bunch of windows pop up quickly and it allows me to see that what is supposed to be printing to the screen is, in fact, showing up. I just can't get it to STAY up (haha).

As an aside, I've been writing a 'quit' sequence into the programs just to keep them up.

The book is old, "C++ From the Ground Up" By Herbert Schildt.

Is it the code? The compiler? I feel like something isn't clicking because no mention of this has been made in the book.

double beltSpeed(double inRotVel, double dw1, double dw2, double dw3)
A function to compute the output (blue) belt speed, s, for the belt driven conveyor system as illustrated. inRotVel is the rotational velocity of the driven wheel (w1) in rpm, dw1, dw2 dw3 are the diameters of the wheels, as illustrated in metres. Your function must call rotationalVelocity to compute the rotational velocity of w2 (and hence w3). Hint: The speed of a point on the edge of a wheel turning at w radians/sec, with radius r is r*w.

I cant really figure out exactly how to do it, i have the function im calling but i dont know how to exactly call it in order to compute the speed

1/10 for the chance that you're really that deluded

I need help with a programming task.

Programming a 3D-model of a teapot by making and filling triangles. Where do I start?

Hey /sci/,

Does anyone know of a good place online to learn some visual basic? In college I started out in C, and missed the whole OOP bandwagon. I specifically ask about VB (2010 to be exact) is because we use it a lot at work and it _should_ be an easy transition to C++ and the like.

Thanks.
