vector<int> ivec {10, 11, 12}用到了c++11的新特性，初始化列表，initialize_list 而vistual studio 2012并不支持c++11这一特性。代码 vector<int> ivec(10,-1);正确，是因为 vector 存在这个版本的构造函数 explicit vector (size_type n, const value_t

第三部分 为已分配的空间填充值 这一步用了vector的一个成员函数_M_fill_initialize(__n, __value)。它的定义如下: 1297 void 1298 _M_fill_initialize(size_type __n, const value_type& __value) 1299 { 1300 this->_M_impl._M_finish = 1301 std::__uninitialized_fill_n_a(this->_M_imp...
// initialize vectors x,y,z and w. for(int i=0; i<N_VECTORS; ++i) { foo[i].x = float(rand() % 10); foo[i].y = float(rand() % 10); foo[i].z = float(rand() % 10); foo[i].w = 1; } 注意上面的元素索引使用容器的'[]'操作符. 这不是最快的方式, 因为操作符函数...
