if-statement

问题 The following is part of the code for my college assignment. else if (!codeList.contains(userCode)) { i--; // i is the counter for the for-loop } else if (userQuantity[i]==0) { i--; } The first part makes sure that if the user enters the wrong code, the counter i does not increment 1, or rather, it subtracts 1 from the recently incremented counter. This part works fine. The second part however is what I seem to be having problems with. userQuantity[] is an int array and it has to be an array.

问题 I am sure this question has been asked stacks of time but I couldn't find a solution. I am trying to conditionally replace the value of a second variable based on the value of first variable. Here is the data. MAKE Continent 1 HOLDEN US 2 HOLDEN US 3 FORD US 4 FORD US if(gsample$MAKE == "HOLDEN") gsample$Continent = "AUS" Warning message: In if (gsample$MAKE == "HOLDEN") gsample$Continent = "AUS" : the condition has length > 1 and only the first element will be used 回答1: Based on the logical

问题 I couldn't figure out what's the problem on my code. Basically i'm trying to do a small version of Monte Carlo simulation. This is my input mydata=[1,4,20,23,37] prediction=c(0,0,0,0,0,0,0,0,0,0,0,0) randomvar=runif(12,0,1) and then i have this condition: if i-th value of randomvar is > 0.97, replace i-th value of prediction with 5th data from mydata else if i-th value of randomvar is > 0.93, replace i-th value of prediction with 4th data from mydata else if i-th value of randomvar is > 0.89,

问题 I have one function which is having if elseif conditions and the cyclomatic complexity is approaching 5. How do I reduce it? function testFunc() { var step = getModel('step'); if(step === 1) { this.resetTask(); //calling some function this.updateStep(0); return true; } else if(step === 2) { this.initTask; //some other function return true; } else if(step === 3) { this.name === 'add' ? this.add() : this.edit(); return true; } return false; } tried replacing with switch case but it didn't help.
