size(); ++i) { std::cout << myArray.get(i) << " "; } std::cout << std::endl; return 0; } 这个例子展示了如何使用非类型模板参数N来指定FixedArray的尺寸,使得我们可以创建具有编译时确定大小的静态数组。 从C++11到C++20 所有跟模板相关内容都梳理到以下这篇文章中,恶补一下把; 面试时...

A + sign behind the name indicates this type has a tail. The tail here is mem, which is specified as array with no size. a length function could be implemented with this signature: fnlen(String+t mut * self) {returnt; } again, the + indicates a tail. in this case, the tail size...
