Compilation error from "Serial Input Basics" tutorial code

I tried using the code from example 2 and I’m getting a compilation error from the line below.

if (rc != endMarker) {...}

The error reads:

ISO C++ forbids comparison between pointer and integer [-fpermissive]

Suggestions?

No problems here.

    char endMarker = '>';
    char rc;

maybe there is a typo in you sketch.
