Use of string class in c++

[Awantika Singh]

My C++ compiler is not accepting string as a predefined class. No objects of string class could be created.

Do you mean the std::string? Did you add the #include

Hello, some more details would be helpful! Do you mean std::string ? If this is the case did you include ? :

#include

then use std::string :

std::string astring("a string");

I've included the header file but "using namespace std" this line is also not working.

Quote:

not working.

What does that mean? Generally speaking: nothing. Please do not expect us to guess what you are doing. Edit your question, show the code you are using, the exact error message that is produced, and which line of code it occurs on.

[Stephane Capo]

I agree with other messages, we can not guess everything. My best guess is that you are compiling a C file? (not C++)...

Or, he could be using an ancient version of C++, like maybe Borland Turbo C++, that doesn't understand namespaces.

But of course, "not working" could mean anything at all.

The following code should compile (and run) fine in a decent (i.e. reasonable recent) compiler

#include using namespace std;

int main()
{
const string greetings = "Hello world!";
cout << greetings << endl;
}

Try adding #include ;)

GOTOs are a bit like wire coat hangers: they tend to breed in the darkness, such that where there once were few, eventually there are many, and the program's architecture collapses beneath them. (Fran Poretto)

There's no need, actually.
