Answer to Question #67217 in C++ for Eunsu Kim

Question

#define KB * (0x1 << 10)

I think it's written to show kilobyte as KB. what is * (star) ??

what is difference with this "#define KB (0x1 << 10)" ??

thanks

Answer 1

Firstly, star (*) sign means a pointer (or reference) to a variable.

Secondly, there is impossible to get the address of const value (0x1 << 10), so calculation of expression *(0x1 << 10) will always cause a compilation error.

Also, probably, the task is incomplete to understand what is asked correctly.
