10001st prime number?

Project euler problem, I think

Ya correct

Francisco

I solved it some months ago

Tokin

Is anyone here topcoder red?

Tokin

Or are they just fairytales

Tokin

Jk

This is the program to find 10001st prime number. I am getting floating point exception error. Please let me know what I have done wrong

I always had problems with prime numbers

StrikeShott

I am thinking of applying greedy approach. Does anyone know how to import vector in c++. ?

StrikeShott

Or do any of you think other approach to get the result. ?

#include<vector>

Dima

Read the rules

Dima

no asking for assignment solutions

StrikeShott

#include<vector>

Already tried that.

Read the rules

He's asking about the idea

Anonymous

Already tried that.

So, it is the only way to import vector

Anonymous

If it doesn't work, you are doing something wrong

Anonymous

#include<vector> ... std::vector<int> vector; // empty vector

StrikeShott

Thanks. Let me try this.

StrikeShott

Or maybe should i just stick with array because the size is defined already in the question. ?

StrikeShott

a[6][6], b[7][6], c[10,6];

correctmaninwrongplace

I would recommend you the occam's razor

correctmaninwrongplace

And i think that maybe other approach would be better, but greedy can work

Anmol

int *arr = new int[100](); Does this initialize the array arr to 0?

Anmol

int *arr = new int[100](); Does this initialize the array arr to 0?

I searched in google for quite a bit cannot find anything concrete

I_Interface

int *arr = new int[100](); Does this initialize the array arr to 0?

{ } probably ?

Anmol

{ } probably ?

No

Anmol

The syntax is perfectly fine

I_Interface

int *arr = new int[100](); Does this initialize the array arr to 0?

this is cpp, use std::vector

I_Interface

int *arr = new int[100](); Does this initialize the array arr to 0?

yes, it is

Anmol

this is cpp, use std::vector

I'm not really familiar with vectors yet so I'd rather not

I_Interface

I'm not really familiar with vectors yet so I'd rather not

but they are more effective than dynamic arrays

I_Interface

int *arr = new int[100](); Does this initialize the array arr to 0?

std::vector<int> my_vector(100,0);

Anonymous

but they are more effective than dynamic arrays

Let him make his own mistakes so he can learn

I_Interface

Let him make his own mistakes so he can learn

even if he will use smart pointers for this ? :D

Mat

int *arr = new int[100](); Does this initialize the array arr to 0?

arr will not be zero

Mat

For the elements inside, you can try yourself

Anmol

For the elements inside, you can try yourself

I did and it always came out to be 0 that's why i asked

Mat

However you should use std::array and std::vector

Anonymous

Best book for C if I know nothing can anybody suggest .

dennis Ritchie

Anmol

I'm not very familiar with templates. I was only taught C and they are now teaching OOPS using C++

Mat

I'm not very familiar with templates. I was only taught C and they are now teaching OOPS using C++

Who talked about templates?

Anmol

Who talked about templates?

Are array and vectors not used as templates?

Anmol

I'm slowly learning the workings of C++

Mat

Just read about them

Anmol

Just read about them

I will as i get there

Is there any possibility to do cgi programming without using any library such as cgicc

Mat

Is there any possibility to do cgi programming without using any library such as cgicc

Writing all you need, yeah

Wim

Is there any possibility to do cgi programming without using any library such as cgicc

Sure, thats not that hard either

Wim

Flat out CGI just sets environment variables which you can read and parse

Anonymous

Ah ok that's great

Thanks

Hi all, please help? I am wondering how to include uuid.h, when I have another header that already has uuid_t defined?

Dima

Welcome

Dima

Try to include it in different implementation files

Timothy

I only have one main file at the moment.

Timothy

I am trying to include this: #include <uuid/uuid.h> And use this function: uuid_parse

Dima

I am trying to include this: #include <uuid/uuid.h> And use this function: uuid_parse

Where’s your second header then?

Timothy

Where’s your second header then?

It's a bluetooth header that I need.

Timothy

#include <bluetooth/sdp.h>

Timothy

Is there a way to only import one function from uuid.h?

Timothy

hmm so I used my common logic and copied the function from the header file into my main file, and renamed the conflicting type..... Probably very evil of me, but I'm keen to hear the "proper" way to do this.

sounds good to me

Drew Diligence

better to steal the relevant code than import bloat // from <uuid.h>

that is the one way to deal with redundant winapi names also

Is there anyone in the group who done with cdac?

Ye kya h

What is this.

Its eeee

Anonymous

It's a demonstration of really cute usage of #include and #define to build a program that looks ridiculous below the region where the pre-processor directives would normally be

Anonymous

Yes

Foxner

Could one use whitespace unicode characters instead?

Foxner

Or would compiler not consider them as valid characters?
