Answer 2

It depends on the compiler and the architecture. Type sizeof(long); etc etc, which will give you the size of that type in bytes.

Answer 4

yes, it depends on the size and architecture. But usually Signed char is 8 bit (-128 to 127), Unsigned char is 8 bit (0 to 255), double is 64 bit (0 to 64k-1) to long is 32 bit. but there are char like long signed, double Unsigned too.
