What does this error mean?

[Unregistered]

I'm using Bloodshed Dev-C++ and I just started learning C++, so please dont get mad at me if the answer is obvious:

I just wrote a small program, and it gives me this error:

Line 16 c:\c__sou~1\q.cpp
initialization to `char' from `const char *' lacks a cast

could anyone tell me what this means?

Thanks!
