Question

I’ve been playing with pointers to better understand them and I came across something I think I should be able to do, but can’t sort out how. The code below works fine – I can output “a”, “dog”, “socks”, and “pants” – but what if I wanted to just output the ‘o’ from “socks”? How would I do that?

char *mars[4] = { "a", "dog", "sock", "pants" };

for ( int counter = 0; counter < 4; counter++ )
{
  cout << mars[ counter ];
}

Please forgive me if the question is answered somewhere – there are 30+ pages of C++ pointer related question, and I spent about 90 minutes looking through them, as well as reading various (very informative) articles, before deciding to ask.

Answer 1

mars[i][j] will print the j‘th character of the i‘th string.

So mars[2][1] is ‘o’.
