和#define的区别 const在C和C++中的区别 constexp C++ static static和const的区别 extern C++ volatile restrict C++ explicit friend 堆和栈 两者都存储在计算机RAM(也就是内存条)上,两种内存分配的两个统称。有多种实现方式,只要符合如下特征就算。 栈(Stack)是为执行线程留出的内存空间,附属于线程。常用后进先...
GCC 编译器通过the __attribute__ ((constructor))关键字支持自定义设计您可能希望在程序启动前完成的例程。注册程序终止后要调用来清理的_fini()和_rtld_fini()函数。通常,_fini()的动作与_init()函数的动作相反。GCC 编译器,通过__attribute__ ((destructor))关键字,支持在程序启动前您可能想要完成的例程的...

comp.lang.c++.moderated 上去看“Guru of the Week #66: Constructor Failures”。)注意function try 可以映射或转换异常:X::X()try{throw 1;}catch (int){throw 1L; // map int exception to long exception}这样看,它们非常象unexpected 异常的处理函数。事实上,我现在怀疑这才是它们的设计目的(至少是对...
