As previously noted, no one wants to wade through code like this.
Please provide any specific error messages or things that are happening that you don't want to have happen.
And please, post your code on a Web server:

Reply:One problem i notice is that in your CalcNutCosts function these statements are unreachable:
tax = subTotal * .0675;
totalPrice = subTotal + tax;
because you have your break; statement above them but you have the closing } for the switch statement after them and since you used the parameter modifier out on tax and totalPrice you will get an error because you are unable to set their values. Try moving the closing } of your switch statement after the break; but before where you set the value of tax and totalPrice like this:
case'W':
case'w':
subTotal = pounds * WALNUTS;
nutName = "Walnuts";
break;
}
tax = subTotal * .0675;
totalPrice = subTotal + tax;

Required Code in language C for driving a hardware ckt. connected through serial or parllel port?
can someboday give me programme code in Language C and the ckt. diagram of optocouplar driven realy ckt. that i can run by using C programming?
Actually, i want to operate a relay with the help of C programming language , now the signal through the parllel or serial port will not be enough to drive the relay , so i need an electronic circuit that will accept the signal from the parllel or serial port and them amplify it or process it and make the signal so strong , so that it can further operate the relay. this electronic circuit will contain optocouplar IC in oder to have isolation between relay circuit and Computer,
So can somebody provide me some link or can email me this circuit diagram and programming Language C code for operating this circuit?
Required Code in language C for driving a hardware ckt. connected through serial or parllel port?
The simplest thing is to use simple driving CCT, using Transistor to drive relay, and don't forget to put a diode to kill the magnetic feedback of the relay coil (free wheeling diode).
You may search the internet for such CCT.
The programming is the funniest part, where you play with the logic binary to control the relay(s)
regards,
:)
Reply:Its so simple its not funny
you use a 9 pin comm port
send a DTR signal to it
a single transistor inverts the logic and
provides the current for the relay coil
I did that over 20 years ago when I invented
the cash drawer that opened by program command
on an 8 bit Atari computer . Later modified it so
it would work on Novell Network Stations
so Video stores could use them.
Added a modem port DTR command to the end of the printer routine. after reciept printed drawer opened
Find the Line feed pin in your centronics port and use the
printer line feed command to change state of pin
will go high for a short duration . feed the high into a NPN
transistor with a good voltage supply at collector
coil voltage will appear at emitter until base goes low

Changing Visual C++ code to Visual Basic 2005 Code?
Hi, i found this code but it says for for C++ but i have visual basic 2005 and i need your help to convert it into visual basic 2005.
Can someone please convert it into visual basic 2005 code
here is the code
the website is
http://geekswithblogs.net/kobush/article...
the codes in yellow background are the codes that i need to convert. can someone please convert those codes, put together, and reply over here with the visual basic 205 form of that coding.
thanks bye

C code question (about variable assignment)?
Be given the code below:
#include%26lt;stdio.h%26gt;
struct test{
unsigned a:3, b, c;
};
void main(){
struct test x;
x.a = x.b = x.c = 10;
printf("%d %d %d ", x.a, x.b, x.c);
x.c = x.a = x.b = 10;
printf("%d %d %d", x.a, x.b, x.c);
}
/*
PRINTS:
2 10 10 2 10 2
*/
After laborious Google searches, still couldn't find exactly what the ":" in "a:3" struct declaration does. Anyone have an idea?
C code question (about variable assignment)?
It's for so-called "bit fields".
:: unsigned a:3;
basically means that variable 'a' will be three bits wide.
It's almost as evil as goto (because its completely unportable), so you shouldn't use it for real software.

Urgent..change C++ code to C?
hi,
My friend did this program for me in C++ ,and he doesnt know any thing about C,
then our lecturer told me the whole code should be in C language,so I changed some of it and the rest I couldnt .
I couldn't find library in C instead of
#include %26lt;Conio.h%26gt;
also there are some functions should be manipulate it .Can you help me plz?
i put the whole code in this link:
http://www.freewebs.com/radicalfunction/...
ur help highly appreciated..
Urgent..change C++ code to C?
Here is the source that compiles under C.
I had to write the clrscr function, defined the getch macro, change Stdio.h to stdio.h, deleted the Conio.h line. Then it worked.
http://www.thehansens.com/free/DealMatri...
Reply:conio.h works with c
your code seems almost working in c
save the program with c extension and the run it
it will work i think if not by errors u can see wats wrong and it would be easy for u to change
Reply:First, in order for your functions to follow your main(), you need to include function prototypes. You'll get a compiler error about not knowing what your functions are. Either move all of your functions above main() OR include function prototypes above the main() function as in:
int menu(void);
Next, clrscr(); is not an ansi function and won't be recognized by many compilers. You either need to figure out what the correct escape sequence is to clear the screen and include that in a printf statement, or issue something like system("cls");
Lastly, the exit() call requires stdlib.h

int num3 = num1 = num2;
That line is the culprit. Just before that, you assigned two different values to num1 and num2. Then why are you assigning num1 the same value as num2 now? Looks funny. Hence, there is your problem. To fix this, you need to find out what's the real algorithm. May be
int num3 = num1 - num2
??
or
int num3 = num1 + num2
??
something like that?
Reply:Pretty sure your problem lies in these 3 lines somewhere.
int num3 = num1 = num2;
int num4 = 10 - (num3 % 10);
if (num4 != 10)
the firstline I don't understand why you did some calculation for num1 and then assigned num2 to num3 and num1...you just lost the result from the first calculation and num1, num2, and num3 now all hold the same value.
I would make sure that what is stored in num3 can be evenly divided by 10 (10,20,30, 340, etc)

do an if mod 2 on the string length to figure out if it is even or odd, if it is even generate two strings from the original by going from 0 to length/2 and length/2 to length.
For output cout from within 2 loops, one after the other, the first loop dealing with the first substring, the second loop dealing with the second substring.
The loop will simply start at the length of the substring and decrement to 0, each time printing length number of characters from the substring to the screen.
The second loop will do the same but in reverse, starting at 1 and stoping at length.
Don't understand what you ment for odd numbers but it will be similar to the above.

I have tried using the WHILE for several hours. Unknowing I had to use the FOR all along.
#include %26lt;iostream%26gt;
using std::cout;
using std::cin;
using std::endl;
[code]
int main()
{
//declare variables
const char asterk = '*';
int a = 9;
int b = 0;
while (a %26gt; 0)
{
b = a;
while (b %26gt; 0)
{
cout %26lt;%26lt; asterk;
b = b - 1;
}
a = a - 1;
cout %26lt;%26lt; endl;
}
//end while
return 0;
} //end of main function
..........C++ code?
//Decreasing
int main()
{
//declare variables
const char asterk = '*';
int a = 0;
int b = 0;
For(a = 9;a %26gt; 0 ; a--)
{
For(b=a;b %26gt; 0 ; b--)
{
cout %26lt;%26lt; asterk;
}
cout %26lt;%26lt; endl;

C++ code???
I have to write a program for my class that reads a file that contains words and numbers. Once they are read in I have to use either peek() or putback() to determain weather or not they are words or numbers and then take them and put them in to 2 different files.
With the code that I have attemted to write I cant get the whole word or number to get put in to the file I get something like this
In the file I have hello 543
the output I get for this is
h
e
l
l
o
5
4
3
3
rather then
hello
543
how do I use these to functions to write the code???
Thanks
Nick
C++ code???
Well, your output has a newline or '\n' after each char. That's why the printout looks like that. And you are getting the last char read twice. make sure you read until EOF
You should read the file by char. If you use the peek, you get one char, determine what it is, say a char and then peek at the next, if its a char, get it, if not put it back and get the next char. Loop through till end of file. Close file.
Then open File do the same thing for numbers. Then each will have their own file.
Reply:u must have used line feed dont use line feed
Reply:actually it depends upon your code.. what u r using.. so better to give description of the code.
but it seems to be..that there might be a mistake in declaring variable type.. like int,or float. etc.
also check foe getch(); and clrscr(); library functions
Reply:Question to your question actually, what function are you using to put the characters into the file? I'm sure people could be much more helpful if you are willing to post the code you do have so far.
Reply:peek() returns one integer at a time. That integer represents the ascii character code. If you're using peek to read in a whole line, you'll have to read until you see the newline character '\n'.
