问题 I am trying to declare local variable like: DECLARE @thresholdDate DATETIME = '2014-11-30' And I am getting error: Cannot assign a default value to a local variable.

问题 Take, for example, the following code: #include <iostream> #include <string> int main() { print("Hello!"); } void print(std::string s) { std::cout << s << std::endl; } When trying to build this, I get the following: program.cpp: In function ‘int main()’: program.cpp:6:16: error: ‘print’ was not declared in this scope Which makes sense. So why can I conduct a similar concept in a struct, but not get yelled at for it? struct Snake { ... Snake() { ... addBlock(Block(...)); } void addBlock(Block

问题 I want to declare multiple variables in a function: function foo() { var src_arr = new Array(); var caption_arr = new Array(); var fav_arr = new Array(); var hidden_arr = new Array(); } Is this the correct way to do this? var src_arr = caption_arr = fav_arr = hidden_arr = new Array(); 回答1: Yes, it is if you want them all to point to the same object in memory , but most likely you want them to be individual arrays so that if one mutates, the others are not affected. If you do not want them all
