... any element in the array like this
printf("Second char is: %c", a[1]);
Index 1 since the array starts with element 0. :-)
Or you could equally do this
printf("Second char is: %c", *(a+1));
The pointer operator (the *) is needed since we are telling printf that we want to print a character. W...
