问题 I want to add two arrays by simply writing: int a[4] = {1,2,3,4}; int b[4] = {2,1,3,1}; int sum[4] = a + b; I wrote this function but I got an error int* operator+(const uint32& other) const{ uint32 sum[n]; for(int i=0; i<n; i++){ sum[i] = (*this[i]) + other[i]; } return sum; } Could you help me on this? Thanks in advance. 回答1: This is probably wrong, but it appears to work (C++11): #include <iostream> #include <array> using namespace std; template <class T> T operator+(const T& a1, const T&

问题 I need help with my add method in java. It works with DoublyLinked List. I am implementing a cyclic DoublyLinkedList data structure. Like a singly linked list, nodes in a doubly linked list have a reference to the next node, but unlike a singly linked list, nodes in a doubly linked list also have a reference to the previous node. Additionally, because the list is "cyclic", the "next" reference in the last node in the list points to the first node in the list, and the "prev" reference in the

问题 I'm making a multiplier in a very simple assembly language in which I have BEQ, NAND, and ADD to create a SRL. I also have to keep the multiplier under 50 lines (16 used thus far) so hopefully the solution can be thrown in a loop. EDIT: My question is how can I implement an SRL with just a NAND and an ADD Had an idea although it is very inefficient, maybe someone can improve it: Decrement say, a, by 1. Store that value in b. Add b and b and store in c. Beq c with a, if it's true then b is
