Hello members, In a book I found some C++ code I changed to C but then got a compiler error which I don't understand. See the demo listings below, C versus C++. A const variable is not accepted for the definition of an array with constant size, and results in an error "Variable length array is not allowed at file scope" although the variable is defined as const. I tried some CFLAGS, used __const__ instead, and searched the archives without success. It seems that the "const" qualifier for the C-compiler is not really constant. Can this be explained and is it possible to avoid this error with some build options which I'm not aware of?
In C++, 'const int' is an actual compile-time constant. In C, it's just a non-writable variable. Not quite the same thing.
