std string help!

[pspballer07]

I want to use string in std but I get errors when I do:

using namespace std;

and when I try this too:

std::string blah;

How do I use string?

I think its because i am using C and not c++ but how would you do it in C?

[a_noob]

if you are using namespace of std then why are you calling it as std::string ???

I take it you are wanting to use C++ standard strings.

take a look at this resource C++ Strings

ok, I changed my code to c++, using namespace std works but now it says 'string' undeclared

[a_noob]

Care to post your code?
Hint: #include <string>

[pspballer07]

Actually it was <iostream>

I decided to give up with strings because I got it to work but then I had all these undefined reference errors after it compiled.

So my next question is this: Take a look at the code

void Reader(char str[][])
{
       //do stuff with str
}

int main()
{
     //do stuff
     char data[1][20];
     strcpy(data[0],"Hello");
     Reader(data);
     return 0;
}

ok but I get these errors:
array has incomplete element type

and for the call to Reader() I get the errors:
incompatible types in assignment
type of formal parameter 1 is incomplete


I tried using char** instead but that doesn't work either

help!

You can't use STL strings or namespaces in C because they were introduced in C++...

And you do need to do #include <string> to use STL string in C++.

You should *learn* C++ .
not trying to discover it this way

ok but look at the post right before yours, I have a question
-= Double Post =-
OK, after a ton of trial and error, I solved my problem
I ended up using char *data[] instead of char data[][]

[hallo007]

we have a c/c++ help thread , ask your questions there just like everbody does

The undefined errors are from NOT linking the C++ STL library. Look in the C/C++ help thread to see how.

sorry

As for your code try just passing Reader(char *str) A pointer will work for any type of array you have. And then call it like so Reader(&data);
