Let's start with buffer not clearly defined in this code snippet.

This loop either never runs or never stops.

This loop either never runs or never stops.

c is a const pointer to char, buffer[i] is presumably of type char. c
is not an l-value (something that can be reassigned).

This is a loop that either never runs or never halts.

Believe the compiler when it gives you an error. The compiler is either
correct or not standards compliant, but those are about the only two
options.
