The problem is your declaration of name as an int. get_string tries to return a string (or char array). It can't store the string ( a char array )in an int. The second error is similar. Since name is an int, it cannot be treated as an array.

Correct the var type of name and it should work.

  • You wouldn't declare name as an array of char (and especially not as a "string array" as you wrote), but as a pointer to char, maybe aliased as string (declared in cs50.h as being char*).

  • I was trying not to give away the actual solution, so that Rahul could figure it out, but the following would work just fine: string name = get_string(); At this point, keep it simple. ;-) But you were right that it should not be a "string array", i.e., an array of strings. I have corrected that. thanks.
