A 2-dimensional array, also known as a 2D array, is an array that has data spread out in two separate directions. In VBA, a 2D array is declared by specifying the number of rows and columns that it will have, and each element in the array can be accessed using two indices, one fo...
在您的初始化程序{std::array<double,2>{0,0},{0,0}}中,子初始化程序std::array<double,2>{0,0},{0,0}不以左花括号开头,因此可以用于初始化C数组的元素,这是可以的(递归地,{0,0}可以用于初始化std::array<double,2>,因为子初始化程序0,0不以左花括号开头)。 建议:使用这个花括号省略规则,您...

Euclid also allows the programmer to specify finalization code that will be executed at the end of a module's lifetime. This feature is not needed for an array-based stack, but would be useful if elements were allocated from a heap, and needed to be reclaimed. Sign in to download full-...
