Ok I'm not too sure. But this might have something to do with dependancy. Is there more than 1 makefile in your download?

One of Dev-C++ shortfalls is it can't compile multiple projects all at...

DEV C++ compiles C or C++ just fine. What is the reported error ?

The links you posted give me a 404 page not found error.

It works but it is platform dependant and incurrs a lot more overhead than getchar(). Most C/C++ developers of any ilk will tell you not to use system("pause").

If you search on this site or using...

I'd like to know more about why this is better. I understand the fflush to force the buffered printf output to the screen immediately. But why the cast to void for getchar's return value? Does this...

Read Hamrick's earlier post it's far more elloquent. Where Hamrick talks about the stack pointer moving down to reach the return value of the function. Therefore, all the local variables that were...

Ah thanks Ancient Dragon now we know.

I haven't programmed a lot of C but to the best of my knowledge:


unsigned char ucBufr = NULL;


1. This is not a null pointer, it's a char variable (1 byte set to 0).

If you mean Windows, then you are best searching for C Windows API to find links like this one:

Of course we don't expect you to know all the rules straight off. If you look in my signature there's...

No they are opposite.

I think both goes on the stack both times. Would only go on the heap/free store if you use the 'new' keyword.

Well ok I concede that was perhaps a little strong.

But you are changing tack with the UML arguement. UML is just a method for designing, the field is much narrower you don't 'create' with it. UML...

No no no no no I'm sorry that's completely the wrong way around. (system("pause")/fflush(stdin) getch()/kbhit() are not wood (the language) they are prefabricated table legs/lego bricks made for...

Hmmm...

Yes you should know the language well, but without a compiler (standards compliant or not) it is useless.

The language is just the wood, it is the tool and the "in depth" knowledge of...

But it is clearly defined in the document to which I posted a link. It is important to understand in great depth the tools you work with. It is very possible for a large project to have potentialy...

You are running preprocessor ONLY you said



Did you read the material I posted?

I stated I was guessing and if I have any good material I would quote it.

I came to this conclusion by thinking about it and applying a process of elimination in my mind, by thinking about how a...

I'm guessing here, but I recon they cancel each other out.

All directives run on each instance, so:

Preprocessor finds the first instance of a and runs ALL directives on it
a = b = a
Then...

Doh! ! I can't believe I am soooo thick!

It swaps every instance of a and b so

printf("%d %d", a, b);

becomes

printf("%d %d", b, a);

You havn't done anything with your definitions, try this:

#include <stdio.h>
#define a_b

int main(void)
{
#ifdef a_b
int a = 20, b = 30;
#endif

Strictly that's not true because 1 is divisible by 1 and itself, but 1 isn't prime. I prefer:

A prime number has precisely two positive integer factors.

Drat, just when you think you know something, it turns out you don't know squat.

Take the first item in the array 0x08

we know from the 0x it's a hexidecimal number (base 8) 0x is how you identify a hexidecimal number the 08 represents the number in decimal thats 8 in binary...

I compiled and ran your code and it worked as expected for me no problem. What exaclty are you inputing and what exactly is the response you're getting?

Oops you posted just before me. The code...

Ternary operator perhaps ?


int a = 1;
int b = 2;

int c = ((a > b) ? a : b )

you can't edit a post more than 30 minutes after you posted in this forum.

0 and 1 are not prime. Yes 1 is divisible by 1 and itself, but that's the same thing it's only one factor not two factors...

Actually dud543 I think this is wrong:|| n % 2 == 0)

That would return false for 2 which is prime.

Dude543 yes I like that very much.

Salem good feedback.


So system("PAUSE") then, what gives ? I havn't found anything negative on the internet yet.

Ok I've found it:

Ok whats wrong with system("PAUSE") ?

I

Ah it's just occured to me what Salem meant by square root !

A revised edition:


#include <iostream>
#include <cmath>

using namespace std;

Ok here's my best shot. The key rule for a prime number is:

It has precisely two positive integer factors.

So the neatest solution I can think of counts those and quits the for loop as soon as...

DOH! Salem

Johns' while loop was: less than OR EQUAL to 500.

So change to for i < 501 NOT 500.

This is Johns' future your playing with, pay attention.

Here you go. Added for loop in place of while, and commented out the i++ at end of while loop.

Also added int variable col, to print a newline every ten numbers printed to standard out.
