sizeof…

Here is a simple way to find the size of an object without using the sizeof operator,

class CTest { … }

CTest oCTest;
CTest* pCTest;
unsigned char* pStart = NULL;
unsigned char* pEnd = NULL;

pCTest = &oCTest;
pStart = (unsigned char*)pCTest;
pEnd = (unsigned char*)(++pCTest);

//size gives the size of the object oCTest.
size_t size =  pEnd – pStart;
