Problem in <string> class copy function

[abdalimran]

I'm trying to copy a part of a string to an array using copy function.

Why does the following code not giving expected output?
What is the reason and how to solve it?

#include <iostream>
#include <string>

using namespace std;

int main ()
{
    string str = "First Name: Abdullah";
    char fname[255];
    cout << "str is: " << str << endl;

    int n = str.find(':');

    str.copy(fname,9,n+1);   // copy to array fname, how many char to copy, starting position

    fname[n+1] = '/0';

    cout << "fname is: " << fname << endl;

    return 0;
}

On line 16, '/0' should probably be '\0' and I doubt n+1 is the subscript you want to use.

Yes '/0' should be '\0'. And I've rewritten it.
But still it shows some unexpected characters after the output.

How to solve this?

How to solve this?

Given the length of str and the value of n, I imagine the correct index to use on line 16 could be easily calculated.
