Undefined Symbol 'String'

[Sandman669]

Using Turbo C++ 4.5, I get the following error when compiling this code:

#include <iostream.h>
#include <string.h>

int main()

{
String Name;
cout<<"Enter Name : ";
cin>> Name;
cout<<"Hello, "<<Name<<"Nice to meet you!";

return(0);

}


Unidentified symbol 'String' in function main().


Can someone please help me identify the problem? I know that's the string library because I looked for it in the compiler's folders.

Much appreciated. Thanks,

Sandman (Tyler)

you should be including <string> not <string.h>, and also <iostream> not <iostream.h>. String name; should be string name;, notice the lower case s.

EDIT - you'll also either need to add using namespace std; beneath your includes, OR instead of string name; put std::string name;

3 problems:

1) You need a newer compiler/IDE. Turbo C++ is ancient. Here are some better options:

2) You should be including <iostream> and <string>, not <iostream.h> and <string.h>.

3) it's 'string' (lowercase), not 'String'. Also, it's in the std namespace, so it's actually 'std::string'

Including <iostream> and <string> causes more errors. It needs to have ".h" at the end in this case. I'll try downloading a newer compiler and rewrite the code.

I'd appreciate it if someone can edit my code and re-post it so I can see it visually :).

Thanks again.

That's because of your old compiler.

This code will work on a modern compiler:

#include <iostream>
#include <string>
using namespace std;

int main()
{
    string Name;
    cout<<"Enter Name : ";
    cin>> Name;
    cout<<"Hello, "<<Name<<".  Nice to meet you!";

    return(0);

}

Got wxDev-C++. Did what you said and it compiles and runs. However it closes right away after execution. Here is my code:


#include <iostream>
#include <string>
using namespace std;

int main()

{
string Name;
cout<<"Enter your name : ";
cin>>Name;
cout<<"Hello, "<<Name;

return(0);

}


My IDE uses Delphi to compile.

There's a sticky on the forum about this very issue:

Many suggestions for fixing the problem lie within.
