Question

Let’s say I have an array:

string w[10];

and I have a statement:

if(w.size() > 10)
{
  // How would I print out the 11th character?
  char a = w[11];
  cout << a << endl;
}

How would I print out the 11th character? I tried storing into a character a but it didn’t seem to print anything.

Answer 1

Why do you want to print outside of the bounds of an array? Printing any character past the size of your array is undefined and might cause a crash.

Also w[11] is actually the 12th element. Since the array is 0 based the 11th element is w[10].

Do you actually want the array do be dynamically sized? Because if you are trying to use a string perhaps you want an stl string? That is defined in the header <string> and used via

std::string somestring("string you want");
