C++ Strings

[NuclearFusi0n]

#include <string>

void main()
{
string ohnoesBAND;
}

Visual C++ 6 tells me that "string" is an undeclared identifier. What's wrong here?

 

[Ameesh]

why dont you just use char *'s ? there are a lot of functions that you can use.

 

[scorp00]

i think it's: #include <string.h>

been a while though

you should read the book instead of asking for help on anandtech

i'm doing that already, i'm just curious why strings dont work...

 

[Ameesh]

i forgot to answer your question, sorry.



there is no class in string.h called string, so you cannot create a type that doesnt exist.

string.h contents.

a. string.h gives the same error
b. there is no book

 

[scorp00]

try

string ohnoesBAND = " ";

what are you doing this for?

 

[Ameesh]

heres a more legit source and not some crackhead unix man page

 

[NuclearFusi0n]

Ameesh, while you are here, how do i append one character array to another? stupid question? yes. do i know the answer? no

edit: nevermind, crackhead unix man page helped me out

 

[PrincessGuard]

Try:
std::string ohnoesBAND;

char *strcat(char *restrict, const char *restrict);


it adds one string to another 2nd parameter is a const so you may not change that but the first is the tring that you want to add upon

understand?

Ok, I don't use crackhead crap windows compilers
But you may be having a namespace problem.

Try:
std::string ohnoesBAND;

or add:

using namespace std;

above the function declaration.

And why would you ever use char * if you have the string class!

because if he needs to use some of those c style functions somewhere he should just stick with char *'s everywhere.


it doesnt really matter to me which one he uses he should just be consistent all the time because if he is not it becomes a real hassle to change strings back and forth to different formats.

Why not just try and download string.h and string.cpp? Maybe it wasn't included with your compiler? I don't really know, I'm taking AP Comp Sci, and we use a file called apstring.cpp for our strings.

I don't think I've found anything I haven't been able to do with string class, but for legacy code that expects char *, it's easy enough to pass it .c_str()

wait so wtf should i do to make the class string work?

 

[Alphathree33]

Trying adding

using namespace std;

just after your #include

 

[Ameesh]

just write using namespace std; at the top of your code. it should fix you right up.

Does anyone else hear an echo?

 

[NeoSolo]

I think Alphathree33/Ameesh has the right answer. =)

Actually, PrincessGuard had it first, then ergeorge

[edit]I'm being pedantic because suggesting using a pointer to char isn't an answer to his asking how to use a string in C++[/edit]

No are you aren't being pedantic because Ameesh's so-called right solution originally was recommending C char arrays in C++ code. Only later did he qualify that advice by saying it gets confusing to mix & match C and C++ strings in the same code. It only took him a few hours to repeat what a few others had already said to merely get the simple C++ code to compile.
