secondo esempi vari per c++ (schema base)

// nuovi elementi: strlen()
#include <iostream>

using namespace std;

int main() {
  char s[] = "Hello, World.\n";
  cout << strlen(s) << '\n';
  s[strlen(s)-1] = 0;
  cout << strlen(s) << '\n';
  cout << (int)strlen("Hello, ") << '\n';
  cout << (int)strlen("H") << '\n';
  cout << (int)strlen("") << '\n';
  return 0;
}

/* Output:
14
13
7
1
0
*/
