Programming & Design - November 2007

Novice c++ guy here, trying to wrap my head around arrays and functions. This is supposed to be a program that takes the center and radii from 2 3d spheres and determines if they collide.

#include
#include
#include
using namespace std;

struct sphere
{
float center[3];
float radius;
};

bool sphereDist (sphere &s1, sphere &s2)
{
return (pow(s2.center[0] - s1.center[0], 2) +
pow(s2.center[1] - s1.center[1], 2) +
pow(s2.center[2] - s1.center[2], 2)) <
(s1.radius + s2.radius);


}



void main ()
{
cout <<"Sphere collision detection program, by D.R."<< endl;
cout <<"Input the centers of sphere one"<< endl;
cin>>s1.center;
cout <<"input the radius of sphere one"<< endl;
cin>>s1.radius;
cout <<"Now input the centers of sphere two"<< endl;
cin>>s2.center;
cout <<"Please input the radius of sphere two"<< endl;
cin>>s2.radius;

if (sphereDist == true)
{
cout <<"The spheres collide." << endl;
}
else
{
cout << "the spheres do not collide." < }

I am building an html email and I am finished with what I wanted to do but I have a large white space underneath my design and I can't get rid of it.

Please tell me what is causing that space and how to get rid of it.

My goal here is to get rid of the white space, not to redesign the page to make it more compliant, try different css tricks or get the page to work better on firefox or google mail etc. I am only interested in the white space fix.

Can someone look at this code and tell me what it is supposed to do?
for(row=row_index-1; row<=row_index+1; row++)
for(col=col_index-1; col<=col_index+1; col++)

This was the code that was provided to find the number of neighbors of each cell.

I am developing specifications for a client web site. The site will not change very often, however I'd like the ability to modify one or two pages at random. Do I need to worry about what language the site is programmed in? I realize there are a number of new languages, techniques etc. I am wonder how transparent that needs to be for me. I do not have programming or design skills.

I'm receiving the above error, and here's the two parts that are interacting with each other (a page of all switches for controlling the application):

function checked($c1, $c2)
{
switch ($c1) {
case 0:
$c2=='value="OFF"';
break;
case 1:
$c2=='value="ON"';
break;
}
}
?>





$c1==$scheduler
checked($c1, $c2);
echo "";
?>





What's wrong in the code?

i'm trying to make a site where certain pages are tableless. i was to use pure css.. but have a 'table' style apperance. i've designed the page with several divs with fixed widths.. using the float feature. some of these div's are to contain user submitted content.. so.. i'm having an issue with embedded images either exceding the width of the div.. or getting cut off by the right side. is there anyway to have a div stretch to the width of its content.. and default to the fixed width if no content stretches it?

I'm working on a excel program that will allow my Construction business to electronically database our bid system. My idea is to have a main page in excel that will have columns labeled Date, Due Date, and Job Name. Every time a job is going to be bid we add it to this sheet.

From here I need to have the JOB NAME entered manually to be automatically copied(by code or if/than) to another sheet Alphabetically(Other sheets will be A,B,C,D,E,F,G all the way to Z.

Therefore if I enter Trump tower on the Main page it will copy it over to the "T" page automatically.

If I enter Airport on the Main page it will copy it over to the "A" page automatically

If there is a way to do this let me know.

Using an input box (lstInput) and a button (btnCompute) I need to click on the button and enter numbers one at a time in a listbox (lstOutput) it needs to be keeping a running total of the sum

When entering" -1", a grand total will be displayed


Heres my code
Public Class frmPositiveNumbers

Private Sub btnCompute_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCompute.Click

Dim num, total As Double

Total = 0

Do until num = -1

Num = Me.txtInput.Text
Me.lstOutput.Items.Add(num)
total += num

Loop

Me.lstOutput.Items.Add(total)

End Sub
End Class

I keep ending in an infinite loop, I am sure its something stupid I am doing.
