Implement Your Own sizeof Now come to implementation of thesizeofoperator. Thesizeofin C is an operator, and all operators have been implemented at compiler level; therefore, you cannot implementsizeofoperator in standard C as a macro or function. You can do a trick to get the size of a...

In C++, sometimes we have to use virtual inheritance for some reasons. (One classic example is the implementation of final class in C++.) When we use virtual inheritance, there will be the overhead of 4 bytes for a virtual base class pointer in that class. class ABase{ int iMem; }; c...
The basic data types in the C language (char, short, int, long, float, and double) may have different sizes depending on the implementation of the language that you are working with, and the size of the data bus in the central processing unit (CPU) of the target machine. The C langua...
I thought of the following implementation: module store integer(8) :: total = 0 contains subroutine get_mem(x) implicit none total = total + sizeof(x) end subroutine get_mem end module store Now my question is what do I declare x as? I have allocate statements in specific places in ...
class C { int int1; int int2; int i; long l; short s; char c; }; Now the size of this class is 20 bytes. In this case, it is storing c, the char, in one of the slots in the hole in the extra four bytes. Byte alignment or byte padding ...
java中的sizeof(Java sizeof) Sizeof in Java Does Java have an operator similar to sizeof () in the C language? The answer is that Java does not provide any sizeof - (C) - like operator. But we should think about why Java programmers need it occasionally. The C language programmer ma...

A: BFGMiner will compile on OS X, but the performance of GPU mining is compromised due to the OpenCL implementation on OS X, there is no temperature or fanspeed monitoring and the cooling design of most Macs, despite having powerful GPUs, will usually not cope with constant usage leading ...
(And certain minimum range constraints) In most platforms that I've dealt with, sizeof(char) is 1, and sizeof(short) is 2. sizeof(char) must be 1 regardless of actual implementation. regards DS James Kanze #5 Jun 16 '07, 11:05 AM Re: Big-endian, little-endian and sizeof(...
