I feel very very stupid now... I seem to have missed the Rdiff - Threshold = 0 part of your post and that equation looks pretty awesome. I would pressume that T = the Threshold for the problem being found? Does it work for varying radii and threshold values? I am gonna plug that into my program tomorrow and probably feel stupid again lol. Would you be willing to send a pm to me of your work from start to finish when working through the problem so that I can add that to my database of knowledge plz?

You can always try GIT, I'm not a big fan of it myself since I find it too easy to screw projects up by a couple misstypes. Other than that there's for example Mercurial.

You'll have that with any similar software. The best way to avoid screwing up, if you're paranoid, is to use a frontend, such as git-cola for Git or TortoiseSVN for SVN.

R(0) = Initial Area
R(1) = sqrt(2A(0) / pi)
R(2) = sqrt(3A(0) / pi)
...
R(n) = sqrt((n-1)A(0) / pi)

And the differences in Radius are calculated simply using the latest R value, let's say R(n), against the previous R value, R(n-1):

Rdiff = R(n) - R(n-1) = [sqrt((n-1)A(0)/pi)] - [sqrt((n-2)A(0)/pi)]

Slight issue with your maths. The radii should be:

Code: [Select]

R(0) = Initial Area
R(1) = sqrt(2A(0))/pi
R(2) = sqrt(3A(0))/pi
...
R(n) = sqrt((n-1)A(0))/pi

Rdiff = R(n) - R(n-1) = [sqrt((n-1)A(0))]/pi - [sqrt((n-2)A(0))]/pi

Or, alternatively,

Rdiff = [sqrt((n-1)A(0)) - sqrt((n-2)A(0))]/pi

A = r*r*pi, so r = sqrt(A)/pi, not sqrt(A/pi).

I'm having a bit of trouble with a do-while loop. I'm working on a text-based adventure game to practice some stuff I learn in class.

Spoiler (click to show/hide)

Code: [Select]

int mainMenu()
{
//Local Declaration
char command[10];

//Command Prompt
printf("\n\n******************\nEnter a command. Type 'help' for a list of commands.\n");

//Main while loop
while (command != "quit")
{
printf("-> ");
scanf("%9s", &command);
if (command == "help")
{
printf("Here is a list of commands in the game:\n");
printf("Check your progress:     'status'\n");
printf("Move to the next room:   'next'\n");
printf("Rest:                    'rest'\n");
printf("Attack (battle only):    'attack'\n\n");
printf("There may be additional, secret commands. Try to find them!\n");
}
}

printf("END OF PROGRAM");

return;
}

There will obviously be code for the rest of the commands, but typing help doesn't show anything and typing quit will not exit the loop. What am I missing?

You have to use strcmp() to compare the contents of strings, == just tests if the strings are stored in the same location in memory.

[Sirus]

Would strcmp() still be required if I changed the loop and variable to use chars instead?

[fergus]

You can compare char's with ==, but you won't be able to use scanf(), because whenever it writes a string to a variable, it adds '\0' to the end, so the space taken up by the string is one char longer then the actual string.

[Sirus]

So...what do you use instead of scanf? That's the only thing we've used in class so far.

[RulerOfNothing]

A = r*r*pi, so r = sqrt(A)/pi, not sqrt(A/pi).

Not so: if A=r*r*pi, then r*r=A/pi therefore r=sqrt(A/pi).

[Skyrunner]

So...what do you use instead of scanf? That's the only thing we've used in class so far.

I use std::cin>> more than anything else.

I'm getting a 'Error: name followed by '::' must be a class or namespace name' for the std.

[Skyrunner]

If you are using namespace std the code is just cin >> <<variable>>.

Also don't forget to #include <iostream>.

[Sirus]

Eh, still getting errors, though at least the squiggle line under std have disappeared. I'm starting to think I should hold off on this project for a year or so, because it's not being as straightforward as I was hoping
