Nice one :P

Hi all got a puzzle for you!

Find the next two lines of the following sequence:

11
21
12-11
11-12-21
31-22-11
13-11-22-21

Well,

char ADD; isnt actually making a string a containing the word ADD, it simply creates a variable called ADD.

Also A[3] is the 4th element in A, i.e if A was "hello", A[3] would be l (the...

Why dont you just show us what you've got and ask us for help??

Worked fine for me...

Is this your site?

http://www.angelfire.com/linux/willc0de4food/programs/basicinput.c

Just incase anyone didnt know, mine isnt red text its a link

Google for "What are factorials used for"

Well if its any help

it simplifies to:

cos(kL/2) = k/b

half angle formulae?

my bad, forgot that was a C++ source code. I've got a C version but its not on the PC, would mean typing it up. If i get time ill post it.

Do you mean having somthing like:

a = 5
b = 6
a+b =...

// GENERIC PARSER

#include <iostream>
#include <cstdlib>
#include <cctype>
#include <cstring>

using namespace std;

enum types { DELIMITER = 1, VARIABLE, NUMBER};

scanf("%s %s", variables);

but then you need to know how many words there are going to be.

use

gets, or fgets

Or you can use strncpy,


strncpy(name,filename,(strlen(filename)-4));

Or

strtok:

So want every part of the array to be sumed with all the other parts, if not can you say it again, i didnt really understand.

I dont know if you can use:

_getch() and _putch();

But look into them.

If you want to learn object oriented C i found a pdf:

http://www.planetpdf.com/codecuts/pdfs/ooc.pdf

I can tell you how to check if 2 lines are perpendicular:

If line 1 is a, and line 2 is b then to check you need to know the eqn:

a.b =|a||b|cos(theta)

where theta is the angle between them,...

That level of C isnt hard, he has simply added error checking by checking to see wether or not an input has been received. And the:


((input % 2) == 0) ? "" : "not ")

Is basicaly an if...

Sorry for interupting this nice little argument, but did you fix your program?

Hey thanks alot :)

I already changed the NUMBER bit, it was the return's that were wrong.

thanks again for your help!

l == "b" ??

Would help if we could see the whole code.

Can you not try using a for(;;) loop, then start with a getkey function, then have a switch statement...

stdin is from the command line.
