My computer is change from 32 bits to 64 bits, and my operating system is 64 bits Windows 7. I think the pointer in 64 bits operating system should be 64 bits — 8 bytes. However, when I use sizeof(void*) in C++ to get the size of a point, the result is 4.
Why 4??
Your executable is still being compiled as a 32-bit binary. Try compiling it as a 64-bit project.
The operating system makes no difference to the internal size of a pointer if the processor is emulating the program within a 32-bit environment…
In VS2010, head over to the configuration manager, make a new entry under ‘platform’, and select
x64(usually it’s the only other option there)EDIT: Also, make sure you’re passing a
void*to thesizeof()operator.
