Calling C++ from C is a bit harder: we have to manually create non-mangled versions of each function we want to expose. Here we illustrate how to expose C++ function overloads to C. main.c #include <assert.h> #include "cpp.h" int main(void) { assert(f_int(1) == 2); assert(...
NULL is 0(zero) i.e. integer constant zero with C-style typecast to void*, while nullptr is prvalue of type nullptr_t which is integer literal evaluates to zero. For those of you who believe that NULL is same i.e. (void*)0 in C & C++. I wo...
What is the Memory Model in C++11 C++11其实主要就四方面内容,第一个是可变参数模板,第二个是右值引用,第三个是智能指针,第四个是内存模型(Memory Model)。 相对来说,这也是较难理解的几个特性,分别针对于泛型编程,内存优化,内存管理和并发编程。 并发编程是个非常大的模块,而在诸多内容底下有一个基本的概...

現在在套用到複製建構函式被刪除或為私用的類別類型時,std::is_convertable<>::value 會正確設定為 false。 此變更沒有相關聯的編譯器診斷。 範例 C++ 複製 #include <type_traits> class X1 { public: X1(const X1&) = delete; }; class X2 { private: X2(const X2&); }; static_assert(std::...
