if-statement

问题 I would love to simplify my code, with better utilisation of for loop indexes. The goal is to change out all UP once for new UP once, which means take down each UP one and bring it up again. There should always be one in UP state while this process takes place, so I need to cover the following scenarios: up - up == delete -> create -> delete -> create down - down == delete -> create -> delete -> create up - down == delete -> create -> delete -> create down - up == delete -> create -> delete -

问题 Can this logic not be simplified more, the code works, but it has become too much of a spaghetti. The requirements are that there should always be one connection if possible in available state, but I need to take all the available states down and re-create them. these paths I have to cover: if both vifs down, call create if both vifs available, take them down and up one-by-one if one down and one available, bring first up the down one, then take down and bring up the available one if only one

问题 I have the following code setup in a form and I'm getting the "Expected Statement" error. My first time doing this and thought I had the syntax correct, what am I missing? <% If Trim(oQuote("shipmeth"))="FREIGHT" Then Response.Write "Freight" ElseIf Trim(oQuote("shipmeth"))="THRSHLD" Then Response.Write "Threshold" End If %> 回答1: When using nested 2-way conditionals, each conditional must be closed by its own End If : If condition_A Then action_A Else If condition_B Then action_B Else If

问题 I have a nested if in Lua. I have a variable inside the second if layer that I want to use in the first layer. The variable is npcSpecimen . if conditions then local npcType = util.pickRandom(self.npcTypes) local npcSpecimen = "" if npcType == "spacebandit" then local npcSpecimen = util.pickRandom(self.npcSpecies) else local npcSpecimen = util.pickRandom(self.npcSpeciesMutant) end local npcId = space.spawnNpc(spawnPosition, npcSpecimen, npcType) end If written this way, npcSpecimen will

问题 I write down a code which find out quotient after dividing two number but without using multiplication,division or mod operator. My code public int divide(int dividend, int divisor) { int diff=0,count=0; int fun_dividend=dividend; int fun_divisor=divisor; int abs_dividend=abs(dividend); int abs_divisor=abs(divisor); while(abs_dividend>=abs_divisor){ diff=abs_dividend-abs_divisor; abs_dividend=diff; count++; } if(fun_dividend<0 && fun_divisor<0){ return count; } else if(fun_divisor<0||fun
