Any C++ Wiz kids here

[SoundFreakk]

You can try me..
I never actually used c++ but study software engineering so I'm familiar with some other program languages.

Also I could ask a teacher if really needed

[BEEKAY]

yeah stack overflow is great.... they tell you that youre wrong and that you need to learn what you are doing. Its extremely helpful

I disagree with that man. That is with anything you ask no matter where it's at. Hell I see it happening on these car audio forums all the time. It's really how you ask it. I've been programming for years and have always used Stackoverflow as a resource. There is always someone there to help out. You just sometimes have to weed out the trolls.

I realize that but my patience is real thin at this point. This class is complete bullshit. It was supposed to be an application security class. They stopped offering it so they threw all the infosec majors into the available programming class and now we are all in way over our heads and have zero ability to get support. The instructor tells us to use peer review. Well when you have a bunch of people with no interest in a subject or any prior knowledge there isnt alot of peer review to do because no one can help you. And the instructor basically goes MIA since its an online course. Just not a good mix.

Maiko will get you through it dude... or he will die trying.

I trust the kid... balls to bones..

I'm currently doing Java right now. My brother is next to me and went to UC Davis and got a BS for computer science engineering and is currently working for a start up at Silicon Valley.

I can ask him?

So you want to make a class and a program that does the area of a square / circle?

[n8ball2013]

thats all im trying to do this week. lol. I realize program guys are probably like umm thats easy but im far from a programmer you want to put in a firewall I got you. You want to do a risk analysis based on anything i got you. this i got nothing.

I made a program last night pretty much doing this except in Java. Ill uplaod it. Same concept except theres a little different command prompts for Java Vs C++. Do youw ant em to upload it to give you an idea?

My program caluclates + returns the surface area of a box (needed = Length, Width, Height) and the volume of a box.

I wrote the class and a program so they directly relate.

[n8ball2013]

You can it might help

[RyanJ]

So you will need to write a class and a program. The class I named is Box.java . The program I named is BoxTest.java

This program might have a little extra as my professor is all about that EXTRA shit But.... here it is. Im just copy and pasting, but I'll explain it after I post it.

If you would liek to RUN it, I can send it to you via e-mail through a zip file, you can save it, and than use CMD to run it.

This is the class

public class Box
{

// declaring instance variables as double
private double length;
private double width;
private double height;

// constructor with three parameters type double
public Box( double l, double w, double h )
{
length = checkValue( l );
width = checkValue( w );
height = checkValue( h );


}

// get method for length
public double getLength()
{
return length;
}

// set method for length
public void setLength( double l )
{
length = checkValue( l );
}

// get method for width
public double getWidth()
{
return width;
}

// set method for width
public void setWidth( double w )
{
width = checkValue( w );
}

// get method for height
public double getHeight()
{
return height;
}

// set method for height
public void setHeight( double h )
{
height = checkValue( h );
}

// checking if there is a 0 or negative number using if..else and if so, replace with 1.0
private double checkValue( double value )
{
if ( value <= 0 )
{
return 1.0;
}
else
{
return value;
}
}

// method toString
public String toString()
{
return String.format( "length = %f, width = %f, height = %f", length, width, height );
}

// method calculateArea to figure out area
public double calculateArea()
{
double area = 2 * length * width + 2 * width * height + 2 * length * height;
return area;
}

// method calculateVolume to figure out volume
public double calculateVolume()
{
double volume = length * width * height;
return volume;
}
}

THIS IS END OF THE CLASS BOX. This is the code that acutally calculates the area + volume.

Now here is the program. This actually uses the class and runs it.

public class BoxTest
{
// main method begins execution of BoxTest
public static void main( String args[] )
{

// creating an array with the size of 4
Box[] boxArray = new Box[4];

// giving each array random values
boxArray[0] = new Box(1.0, 2.0, 3.0);
boxArray[1] = new Box(-1.0, -2.0, -3.0);
boxArray[2] = new Box(4.0, 5.0, 6.0);
boxArray[3] = new Box(7.0, 8.0, 9.0);

// using an enhanced for loop to print out length, width, height, area, and volume
for ( Box i : boxArray )
{
System.out.printf( "\n%s", i.toString());
System.out.printf( "\nThe Surface Area Of The Box Is: %f", i.calculateArea());
System.out.printf( "\nThe Volume Of The Box Is: %f\n", i.calculateVolume());
}
// Programmer
System.out.println( "\nProgrammed By: Ryan Jin" );
// end main
}
// end class
}

Let me know if this rings a bell. hahah

you woudl have to just change calculateVolume to calculateCircle I guess and calculateArea to calculateSquare
