This has been solved in parts. I am not sure if there are
any better method merging it.

case 1. User passes a variable as the parameter.
eg: int n;
sizeof(n);

case 2. User passes a data type as the parameter.
eg: sizeof(int)


Solution
case 1: #define GetSize(x) (char*)(&x + 1) - (char*)&x

case 2:#define GetMySize(x) (char*)((x*)10 + 1) - (char*)10
