Thread: trouble with checking a string..

Code:

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

int main()
{
    string old_name;
    // presumably assign old_name somewhere in here.
       
    if(!old_name.empty()) // easy to read conditional.
    {
        char* new_name = new char[4];
        strncpy(new_name, old_name.c_str(), 4);
        // do what you got to do with a non-empty c-string
        // All the messy c-string work is isolated here.
        
        cout << new_name << endl;
    }
    else
    {
        cout << "empty" << endl;
    }
    
    cin.get();
    return 0;
}
