Hello,

I am new to programming but i have done basic input output operation, now i want to go for link list programming starting from single list.

so, before that i am having problem with DEv C++ comipler it is not compiling source file.

code is:->
Code:

#include <iostream>
int main()
{
using namespace std;
cout << "hey";
system("pause");
return 0;
}

Select All
and error listed below are.

i:\gw\lib\crt2.o(.text+0x8) In function `_mingw_CRTStartup':
[Linker error] undefined reference to `__dyn_tls_init_callback'
[Linker error] undefined reference to `__cpu_features_init'
i:\gw\lib\crt2.o(.text+0x8) ld returned 1 exit status

I always thought it was

system("PAUSE")

. Remember that C++ is case-sensitive!

NOW ALSO IT FILE not compiled!!

Hi again,

I am getting you what to do for removing linker error, i have seen that link but not getting what to do of that code??

[DimitriV]

Near the bottom in that page. It highlights a potential cause to the error.

A better solution would be to get rid of Dev-C++ and install CodeBlocks instead.

Dev-C++ version 4 was obsolete 5 or more years ago and version 5 never got out of beta and is obsolete.

[DimitriV]

Really? I never would have thought of it.

[r.stiltskin]

Really. I stopped using Dev-C++ at least 6 years ago. I don't think you'll find many serious programmers recommending it.

Ok, after downloading code block:-
I have written this code from some web.

#include <iostream>

int main()
{
 std::cout << "hello world! << std::endl;
 return 0;
}

showing error
fatal error iostream not found!

[DimitriV]

Maybe look here: http://wiki.codebloc...piling_(errors)
I'm not such an expert on compilers but the wiki for code blocks seems a good place to start.

[RRITESH]

OK, now the code is working fine but i don't understand why we require to add..
std::cout << "hello world\n";

what it is important to add std:: without it shows error..

[DimitriV]

It just means that cout is in the std namespace. If you want, use this inside your code:

#include <iostream>
int main(){
using namespace std;
cout << "hi";
system("PAUSE");
}

Or something like that

[RRITESH]

So, i was writing a code for comparing int number and returning output, it was working fine as i want to do.
but in top i don't understand the use of int main(), as typing void main() shows and error can we write char main()??

#include <iostream>

using namespace std;
 int main() {
     int a;
   cout << "hello world\n";
   cin>>a;
   if (a==2)
   cout<<"right";
   else
   cout<<"wrongh";

 }

but i want to compare char then what to do??

[DimitriV]

Did that code work for you? I hope it did.
Is the issue resolved now?
