    5546.cc: In function `int main(int, char**)':
    5546.cc:8: warning: deprecated conversion from string constant to `char*'

A const string (type char*, not string from <string>) can
be overwritten by strcpy

using namespace std;

int main(int, char* [])
{
  cout << "Hello" << endl;
  strcpy("Hello", "World");
  cout << "Hello" << endl;
