String Help!!!

can someone check on this code [error occur]

Code:

---


    cout<<endl<<str.size()<<endl;
    if(str.size() % 2 ==0)
    {
        cout<<str;
    }   
    else
    {
        str.resize((str.size)+1);
    }

---

the error message is

In function `int main()':
invalid use of member (did you forget the `&' ?)

Can you post the whole code or is it too long?

I don't about the error you are showing...you need to give the complete code for that...but there is another error in this code...it should be

Code:

---

(str.size()+1);

---

instead of

Code:

---

((str.size)+1);

---

yeah it is bit long

... and this error would likely make the compiler issue a statement like "invalid use of member", because it's... an invalid use of a member :rolleyes:

But what would & have to do with anything?

Don't know what you exactly want, anyway this is the official syntax:
#include <string>
void resize( size_type num, const TYPE& val = TYPE() );

So, you cannot just add 1 in the resize syntax, as you did here:

Quote:

---

str.resize((str.size)+1);

---

Instead, try something like this:

Code:

---

int newsize = str.size() + ;1
str.resize(newsize);

---

Here's an example:

Code:

---

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

using namespace std;

int main ()
{
        string some_string;
        int new_string_size;
       
        cout << "Enter a string:\n";
        cin >> some_string;
        cout << "string size = " << some_string.size () << endl << endl;
       
        if (some_string.size () % 2 == 0)
        {
                cout << "Your string size is even.\n";
        } else
        {
                new_string_size = some_string.size () + 1;
                some_string.resize (new_string_size);
               
                cout << "Your string size was odd and has now been made even.\n\n";
        }
}
