在实际的应用中，我们需要动态库导出特定的符号(有些接口不对外暴露，只内部使用)，下面的例子展示了具体的实现方式。1. code//log.h#pragma once#define BUILDING_DLL#if defined _WIN32 || defined __CYGWIN__#ifdef BUILDING_DLL#ifdef __GNUC__#define DLL_PUBLIC __attribute__ ((dllexport))#else#define DLL_PUBLI

1. win32或者win64_WIN32 Defined as 1 when the compilation target is 32-bit ARM, 64-bit ARM, x86, or x64. Otherwise, undefined._WIN64 Defined as 1 when the compilation target is 64-bit ARM or x64. Otherwise, undefined.#if defined(_WIN32)#define OS_WINDO

1. std vector中添加元素In C++ vectors are dynamic arrays. Unlike arrays, they don’t have a fixed size. They can grow or shrink as required. Vectors are assigned memory in blocks of contiguous locations. When the memory allocated for the vector falls short of

Both C and C++ support function pointers, which provide a way to pass around instructions on how to perform an operation. But function pointers are limited because functions must be fully specified at...

The ‘const’ system is one of the really messy features of C++. It is simple in concept: variables declared with ‘const’ added become constants and cannot be altered by the program. However it is also...

What is constructor?A constructor is a member function of a class which initializes objects of a class. In C++,Constructor is automatically called when object(instance of class) create.It is special...
